Abstract

The descriptive biology of torrent mites (Parasitengona: Torrenticolidae: Torrenticola) of North America (north of Mexico) is investigated using integrative methods. Material examined includes approximately 2,300 specimens from nearly 500 localities across the United States and Canada, and a few collections in Mexico and Central America. Species hypotheses are derived from a phylogenetic analysis of the barcoding region of cytochrome c oxidase subunit 1 (COI) for 476 specimens and supported with morphology and biogeography. Relationships between species are examined with a combined analysis of COI and two expansion regions (D2–3) of the large ribosomal subunit (28S rDNA) for 57 specimens. All previously described species from the US and Canada are examined. Our results indicate the need to synonymize four species: T. mercedensis (Marshall, 1943) is a junior synonym of T. sierrensis (Marshall, 1943); T. rectiforma Habeeb, 1974 is a junior synonym of T. ellipsoidalis (Marshall, 1943); T. neoconnexa Habeeb, 1957 is a junior synonym of T. magnexa Habeeb, 1955; and T. esbelta Cramer, 1992 is a junior synonym of T. boettgeri KO Viets, 1977. We describe 66 new species and re-describe all previously described regional species. Our findings indicate that total diversity of Torrenticola in the United States and Canada comprises 90 species, 57 known from the east and 33 from the west. We organize these species into four species complexes that include 13 identification groups. An additional 13 species do not fit within an identification group. The southern Appalachians are suspected to contain the highest concentration of remaining undescribed diversity. A key is provided to all known species in the US and Canada.

Introduction

Torrenticolidae Piersig, 1902 are known as “torrent mites” due to the typical habitat of most species—fast-flowing, rocky or sandy-bottom streams (Goldschmidt 2007, Smith et al. 2010, Proctor et al. 2015). In fact, in many streams, torrenticolids are among the most abundant of all arthropods. Adults are active predators that crawl through sandy sediment with stout legs and sclerotized bodies and roam interstitial zones in search of micro-crustaceans (Goldschmidt 2007, Smith et al. 2010, Proctor et al. 2015). The dorsal cuticle of adults is often ornamented with colorful patterns that can be useful in differentiating species, especially locally (Figure 1). Larvae are ecto-parasites of chironomids, but cannot yet be identified to the species-level, so questions such as host specificity and loss of parasitism remain open areas of investigation. This difficulty is compounded by the fact that larval and post-larval stages are difficult to link due to disparate morphologies, although future efforts employing molecular techniques may resolve this issue (e.g., Stålstedt et al. 2016).

Figure 1. 

Diversity of Torrenticola in Ouachita National Forest, Arkansas. Species from top-left to bottom-right: T. irapalpa sp. n., T. interiorensis sp. n., T. biscutella sp. n. female, T. biscutella sp. n. male, T. pearsoni sp. n., T. trimaculata Fisher & Dowling 2016, T. unimaculata sp. n., T. larvata Cherri et al. 2016, T. solisorta sp. n. Note that, for a given locality, many characters necessary for identification can be seen under low magnification. For example, species in the bottom row can be readily differentiated using color pattern. In contrast, species in the top row have similar color patterns; however, even they can be readily identified: T. irapalpa have dorsal glandularia (Dgl-4) closer together than the other species and T. biscutella have fused anterio-lateral platelets and strong sexual dimorphism (neither character is present in T. interiorensis). Only the identification of T. interiorensis is tentative based on this image, because T. neoanomala (not pictured), which are also found in this locality, can only be differentiated from T. interiorensis by comparing precise measurements of the anterio-lateral platelets, necessitating examining slide-prepared material under higher magnification. Also, note that some species can appear differently than what is depicted in species descriptions. For example, although T. pearsoni sp. n. has a nearly colorless cuticle, it can appear dark due to gut contents, as shown here. Image is a composite of stacked images from a Samsung GS7 and edited in Adobe Photoshop.

Torrenticolidae comprises two subfamilies (Wiles 1997): Testudacarinae Cook, 1974 and Torrenticolinae Piersig, 1902. Testudacarinae comprises two genera (O’Neill et al. 2016)—Debsacarus Habeeb, 1961 (one species) and Testudacarus Walter, 1928 (20 species)—and Torrenticolinae comprises five genera: Monatractides Viets, 1926 (approximately 100 species); Neoatractides Lundblad, 1941 (11 species); Pseudotorrenticola Walter, 1906 (eight species); Stygotorrenticola Pešić & Gerecke, 2014 (one species); and Torrenticola Piersig, 1896 (approximately 250 species, not including species described herein).

Torrenticola—the focus of this paper—are found worldwide, excepting Antarctica. In North America, 79 species have been described, most of which are known from Central America due to the efforts of Goldschmidt (2007). North of Mexico, only 23 Torrenticola have been described (Marshall 1929, 1930, 1933, 1943; Habeeb 1955, 1957, 1961, 1973, 1974; Crowell 1960; Fisher et al. 2015; and Cherri et al. 2016) and no comprehensive review is available. Most species are known from only one or a few specimens and sampling has been greatly limited.

The present study is the fourth in a series of ongoing taxonomic investigations of North American Torrenticolidae. The first study offered a detailed description of a single species, diagnoses of higher ranks, and a historical review (Fisher et al. 2015); the second investigated the systematics of Testudacarinae (O’Neill etal. 2016); and the third allowed an undergraduate researcher to describe a species endemic to the Ouachita Mountains, USA (Cherri et al. 2016). Herein, we describe 66 new species and re-describe 24 species, totaling 90 species. The ability to efficiently test species boundaries of such a widespread and diverse genus is a feat made possible with molecular data and by the researchers who contributed to the immense holdings of the Canadian National Collection (CNC), especially Ian Smith, who collected fresh material for molecular analyses. These collections were supplemented with local collections in Arkansas and four expeditions (Rocky Mountains, Pacific Northwest, California, and Alaska).

Methods

Curation: Mites were collected and curated using the protocol detailed by Proctor et al. (2015, p. 649–655) and summarized by Fisher et al. (2015). Specimens collected for molecular analyses were preserved in 95% ethanol, whereas others were preserved in GAW (50% glycerol, 10% glacial acetic acid, and 40% water by volume; also referred to as Koenike’s solution). Slide preparations were created after extraction of genomic DNA (see Molecular phylogenetics below) using either glycerin jelly or Hoyer’s medium. Where available, holotypes and allotypes were designated with glycerin jelly slide preparations, rather than Hoyer’s slide preparations. Unlike Hoyer’s, glycerin jelly does not obliterate body coloration, which can be important in identifying many Torrenticola. However, Hoyer’s medium has superior optical properties, which enables investigations at higher magnification (i.e., greater than 400×). Therefore, when available, some paratypes were prepared with Hoyer’s medium.

Geographic coverage: North America, north of Mexico (Figure 2). Importantly, Alaska, which is not represented in Figure 2, was sampled for water mites, but no Torrenticolidae were found. Similarly, the Great Plains region was sampled, but few Torrenticola specimens were found. These regions likely represent areas where Torrenticola, which appear to prefer cool, clean, mountainous streams, are not present or at least not common.

Figure 2. 

Summary of all sampling localities. 327 red dots represent material examined; 14 blue diamonds represent published accounts where material was not available for direct examination. Each of the 341 localities represent a generalized locality, not an individual collection event, as multiple events often occured in close proximity. In total, this map represents nearly 500 collection events. Note the absence of material from the Great Plains (e.g., Oklahoma, Kansas, Nebraska, and the Dakotas) and Alaska; these are areas that were sampled for water mites, but Torrenticola were not found.

Terminology: We follow the terminology of Fisher et al. (2015), who modified Goldschmidt (2007) and Proctor et al. (2015), with the addition of a new term, “anterior venter”, used to describe the distance between the gnathosomal bay to the genital field (Figure 6C). Colorful species generally have dorsal shades that ranges from bluish to orangish, and a medial stripe that ranges from orangish to reddish. We use the following terminology regarding the darker shade: navy blue – bluish-purple – purple – reddish-purple – orange (Figure 3).

Figure 3. 

Terminology for coloration: blue – bluish-purple – purple-pink – reddish-purple – orange. Species depicted from top-left to bottom-right: T. gorti; T. erectirostra; T. biscutella; T. neoanomala; T. nigroalba; T. gorti; T. skvarlai; T. magnexa, and T. delicatexa.

Images: Color micrographs of slide preparations were taken with a Leica DFC 300× camera using Leica Application Suite software and montaged with Helicon Focus 6 to ensure certain structures (e.g., glandularia) were visible. Resulting image stacks were then edited in Adobe Photoshop CS6 to remove debris, repair damaged specimens, and remove structures that are unnecessary for identification. For the latter, legs were removed from the venter and most setae were removed from the pedipalp. In addition to these structures not being useful for identification, they are also not depicted accurately with photographs. Final images were compared with the specimen and edited accordingly to best approximate realistic coloration. In some cases, specimens prepared in glycerin jelly (i.e., coloration preserved) were not available and only the Hoyer’s slide preparations (i.e., coloration destroyed) were available. For these, micrographs were taken of the Hoyer’s slides and coloration was added in Photoshop (Figure 69, 71). Note that color micrographs depict the best representation of specific characters (venter, dorsum, pedipalp, subcapitulum), so a given figure may be a composite of multiple specimens (e.g., dorsum and subcapitulum of specimen A; venter of specimen B).

Descriptions: The descriptions contained herein are streamlined to include information that best diagnoses a given species, so we depart from the standard of previous descriptions in two important ways. First, we depict species with photomicrographs rather than line drawings, which greatly reduces the time necessary for a given description. Although this is not generally possible with mites, torrenticolids lend themselves to such representation because the characters needed to diagnose species, such as color pattern, are viewable from such images—a condition not common in most mite groups. Second, we depart from the suggestion of Goldschmidt (2007) and recent torrenticolid descriptions (e.g., Pešić 2014; Pešić and Gerecke 2014; Pešić and Smit 2014) in that we do not depict the ejaculatory complex or legs as these systems were not useful in differentiating species that were easily distinguished by other systems (e.g., color, various measurements and proportions). In fact, in those cases where two or more species were difficult to differentiate using our methods (e.g., Miniforma Group), we examined the ejaculatory complex and legs for additional characters. However, in no case could species that are difficult to identify be separated by ejaculatory complex or leg character systems. Therefore, although such systems are morphologically interesting, we decline to describe them here.

Species delimitation: An integrative approach to species delimitation was employed, which included a combination of morphological, molecular, and biogeographic characters. The development of species hypotheses was an iterative process. Initial hypotheses were created during the sorting stage with a stereomicroscope by grouping specimens into recognizable units of overall similarity (i.e., morphotypes). These hypotheses were tested with early iterations of phylogenetic analyses, which was the basis for identifying preliminary clades in need of further sampling. For example, distinctive morphotypes recovered as monophyletic, and with low genetic variability across their distribution (i.e., less than one percent difference in COI), were considered as putative species; additional specimens were not added unless found far outside the known geographic range. In contrast, when morphotypes were found to span multiple clades in COI trees, additional specimens from those lineages were included to generate more data in order to test hypotheses for those morphologically cryptic clades.

Measurements (Figure 46): We generally follow Fisher et al. (2015), who modified Goldschmidt (2007), but with the following modifications. Two measurements were added: the distance between Dgl-4 and the height of the rostrum. The following measurements were excluded as they were not found to be important in diagnosing species: distance from genital field to excretory pore; distance from genital field to cauda; dorsal plate length; gnathosomal bend depth; cheliceral height; width of palpomeres, except for the tibia; and all genital skeleton measurements. For each species, when available, a minimum of five individuals of each sex were measured. An effort was made to include members that spanned the range of variability (morphological and molecular) from across the geographic range.

To increase time-efficiency, Fisher et al. (2015) suggested digitally measuring compound light micrographs of specimens. However, we abandon that method herein, as many closely-related species of North American Torrenticola are identifiable only with precisely-measured ratios. Measurements were found to be highly inaccurate if taken from images that were not in crisp focus. High-quality, stacked images of each structure can negate this problem (e.g., Hamilton et al. 2016). However, creating such images of slide-prepared mites greatly increases the time invested per specimen and was beyond the scope of this study. Therefore, our measurements were taken with an objective micrometer on a Leica DM 2500 compound microscope.

Molecular phylogenetics: Samples from most sites were sorted to morphotype. Male and female representatives of each morphotype, per sample locality, were chosen for extraction. This resulted in clades containing members from across the geographic range, regardless of our initial speculations on species hypotheses. However, the high abundance of specimens in samples from the far west (California, Oregon, Washington) necessitated that each sample be scanned for morphotypes rather than sorting the entire sample. This was likely sufficient to find most species, but increased the likelihood of missing species present in low abundance. For example, despite obtaining abundant specimens of the Miniforma Group in nearly every sample, we were unable to re-collect T. miniforma Habeeb, 1974, even within the type locality.

To test species hypotheses and guide the description process, the barcoding region of COI was analyzed. We then used the resulting tree as a guide to increase sampling in certain geographic regions, or within certain morphotypes. The result is that many species are represented by specimens from across their distributions and spanning morphological variation. We also analyzed the D2-3 region of 28S rDNA in combination with COI to resolve relationships between species. This analysis included representatives of every species group. All sequences have been deposited in GenBank and accession numbers are located in Suppl. material 1. We follow the recommendation of Chakrabarty et al. (2013) in using GenSeq nomenclature.

Genomic DNA was extracted using Qiagen DNeasy Tissue Kit (Qiagen Inc., Valencia, Calif.). The target regions of COI (450 bp) and 28S (725 bp) were amplified with LCOI and HCOI (Folmer et al. 1994) and D23F and D6R (Park and Ó Foighill 2000), respectively, and purified with Qiagen QIAquick PCR Purification Kits. Test gels (1.5% agarose) confirmed PCR product quality. Purified PCR products were sequenced by Macrogen USA (Rockville, Maryland). Forward and reverse sequences were reconciled with DNASTAR© Lasergene SeqMan (Madison, Wisconsin). Resulting contigs were checked for contamination with BLASTn searches of NCBI’s nr database. Sequences were assessed for the presence of nuclear mitochondrial DNA segments (NUMT) by scanning for in-frame stop codons and indels (Song et al. 2008). COI sequences were aligned with Clustal X (Thompson et al. 1997) and 28S sequences were aligned with MAFFT Version 7 (Katoh and Standley 2013); both alignments were conservatively edited with BioEdit (Hall 1999). Bayesian analyses were performed with MrBayes (3.2.2) using the Extreme Science and Engineering Discovery Environment (XSEDE) infrastructure on the Cipres Portal (Miller et al. 2010), which submits jobs to the Gordon Compute Cluster, a network of 16 supercomputers sponsored by NSF XSEDE at the University of California, San Diego. Each analysis consisted of four simultaneous runs, each with four chains sampling every 1000 generations for 20 million generations, under a GTR+I+Γ model of molecular evolution; 50,000 trees were discarded as burn-in. The resulting majority-rule consensus trees were viewed with Dendroscope 3 (v. 3.5.7) (Huson and Scornavacca 2012); tree image files were then exported in PDF format and edited for final figures in Adobe Illustrator CS6.

Type designation: Earlier works have suggested that males should be used as holotypes due to the importance of characters of the genital skeleton (e.g., Goldschmidt 2007). At least with North American fauna, this is not the case, as females are often more distinctive than males, especially within difficult-to-identify lineages (e.g., Rusetria Complex). Therefore, we have chosen female specimens for most holotypes. Of all species in the region, only nine have male holotypes. Of these nine, four are only known from males (T. anoplopalpa Fisher & Dowling, sp. n.; T. bittikoferae Crowell, 1960; T. dolichodactyla Fisher & Dowling, sp. n.; and T. longitibia Fisher & Dowling, sp. n.) and four were previously described (T. delicatexa Habeeb, 1955; T. neoanomala Habeeb, 1957; T. rufoalba Habeeb, 1955; T. tricolor Habeeb, 1957). Only one species (T. interiorensis Fisher & Dowling, sp. n.) has been deliberately chosen herein to be represented by a male holotype, which we have done to reflect that this species can only be readily-differentiated from its sister species, T. neoanomala, with male characters.

When possible, allotypes (a paratypic member of the opposite sex as the holotype) that best embody the proposed species hypotheses have been selected from the paratypic series. Allotypes are connected to the holotype based upon sampling location, genetic variation, and character consistency. Allotypes are considered to be the best representatives of the paratypic series that are also connected to the holotype with greater confidence than other paratypes.

When possible, the entire type series is represented in our phylogenetic analyses. However, we have found that coloration is valuable for species identification, yet for some lineages a given sex is represented only by specimens preserved in Hoyer’s medium, which destroys coloration. To resolve this problem, we searched GAW-preserved material for representatives. These specimens lack molecular data, but in each instance, specimens were selected that adhere to our species hypothesis with high confidence. For example, specimens were preferred if from the same sample or region, and especially from collection events that also lacked similar species.

Deposition: Material examined for both newly-described and previously-described species (holotypes, allotypes, most paratypes, and most other material examined) were deposited in the Canadian National Collection of Insects, Arachnids, and Nematodes (CNC) in Ottawa, Canada. An exception is T. bittikoferae Crowell, 1960, for which we examined two paratypes deposited in the Ohio State University Acarology Laboratory (OSAL) collection. For all species, when additional specimens were available, representative paratypes and other material examined were also deposited in the Acari Collection of the University of Arkansas (ACUA) in Fayetteville, Arkansas.

Results and discussion

Summary of material: Approximately 2,300 specimens representing 90 species were examined from nearly 500 localities spanning the United States, Canada, and a few collections in Mexico and Central America (Figure 2). Specimens preserved in ethanol (for morphology and molecular data) and GAW (for morphology alone) were available for most locations across the US and Canada, but only GAW samples were available from Mexico and Central America.

Herein, we discuss 90 species of Torrenticola from North America. Previously, 23 species were known from the United States and Canada. Herein we propose the following four synonymies: T. mercedensis (Marshall, 1943) is a junior synonym of T. sierrensis (Marshall, 1943); T. rectiforma Habeeb, 1974 is a junior synonym of T. ellipsoidalis (Marshall, 1943); T. neoconnexa Habeeb, 1957 is a junior synonym of T. magnexa Habeeb, 1955; T. esbelta Cramer, 1992 is a junior synonym of T. boettgeri KO Viets, 1977. Five species previously known only from Mexico and Central America are reported from the southwestern U.S.: T. boettgeri KO Viets, 1977; T. keesdavidsi Cramer, 1992; T. kurtvietsi Cramer, 1992; T. lamellipalpis Viets, 1997; and T. rala Cook, 1980. This raises the number of previously described species known from North America north of Mexico to 24. We also describe 66 new species, which raises the total number of species known from the U.S. and Canada to 90. All previously described species are re-described with color images and updated information.

Summary of phylogenetic analyses: A combined dataset of 28S (725 bp) and COI (450 bp) of 42 species (Suppl. material 1) recovered four species complexes (described below) (Figure 78). These complexes were determined based upon a combination of monophyly and note-worthy characters (e.g., postero-lateral plate fusion in the Rusetria Complex; short, conical rostrum in the Tricolor Complex). The Rusetria and Raptor Complexes were recovered as closely related with strong support. However, we consider relationships among species complexes tentative, pending worldwide sampling. Within these complexes, 12 species groups are noted that are helpful for identification (an additional group, the Rala Group, does not fit within a complex), although many of these groups are not monophyletic.

Figure 7. 

Bayesian inferred cladogram for combined analysis (28S+COI) of North American Torrenticola: species complexes and identification groups. Four well-supported complexes are organized into 13 groups that are helpful for identification. Note that 1) not all identification groups are monophyletic (in quotation marks); 2) not all species are placed in a complex; and 3) some species are not placed within a group, reflecting their identification difficulty. Numbers are DNA identification numbers. Dots denote posterior probably >95%.

COI sequence data were obtained for 481 individuals from across the United States and Canada (Suppl. material 1), including all specimens from the combined analysis. These 481 individuals group into 57 clades that represent well-supported species hypotheses (Figures 918). Of these 57 species hypotheses, 13 clades are identifiable to previously-described species: T. delicatexa Habeeb, 1955; T. ellipsoidalis (Marshall, 1943); T. larvata Cherri, Fisher, & Dowling, 2016; T. multiforma Habeeb, 1974; T. neoanomala Habeeb, 1957; T. magnexa Habeeb, 1955; T. nigroalba Habeeb, 1955; T. projector Habeeb, 1961; T. rala Cook, 1980; T. sierrensis (Marshall, 1943); T. tahoei (Marshall, 1943), T. tricolor Habeeb, 1957, T. trimaculata Fisher, 2015; T. ventura Habeeb, 1973. Two clades include multiple previously-named species, necessitating the synonymization of three species. Ethanol-preserved specimens of seven previously described species, known from the United States and Canada (T. bittikoferae Crowell, 1960; T. indistincta (Marshall, 1929); T. kittatinniana Habeeb, 1955; T. miniforma Habeeb, 1974; T. occidentalis (Marshall, 1933); and T. rufoalba), were not available, but the type series for each of these were examined morphologically. Of the 57 species in our molecular analysis, 44 represent new species.

Species Complexes and Groups (Table 1): As considered herein, species complexes are monophyletic collections of closely-related species recovered by our combined (COI+28S) phylogenetic analyses (Figure 78). In addition, most species known only from morphology are placed within the tree in suspected complexes. Species complexes proposed herein and their relationships to each other should be considered a first step in need of future exploration that will greatly benefit from worldwide sampling. Our analyses recover four species complexes: Miniforma; Raptor; Rusetria; and Tricolor.

Four western species included in the molecular analysis do not fit into a species complex: T. ventura Habeeb, 1973; T. raptoroides Fisher & Dowling, sp. n.; T. sharkeyi Fisher & Dowling, sp. n.; and T. rala Cook, 1980. Additionally, fresh material for molecular analysis was not available for six other species that are suspected to be closely related to T. rala and therefore included in the Rala Group (below): T. boettgeri KO Viets, 1977; T. kurtvietsi Cramer, 1992; T. lamellipalpis KO Viets, 1977; T. keesdavidsi Cramer, 1992; T. dolichodactyla Fisher & Dowling, sp. n.; and T. anoplopalpa Fisher & Dowling, sp. n. Collectively these species (T. ventura, T. raptoroides, T. sharkeyi and the Rala Group), resemble fauna from south of the US. The phylogenetic affinity of these species can only be determined with the addition of worldwide fauna, especially from Mexico and Central America.

As considered herein, “species groups” represent closely related species that are readily identifiable to the species group level, often even under low magnification (i.e., stereoscope). The function of these species groups is to aid identification, as often species of a group are easier to recognize at the group-level than the species-level. Occasionally, identifying a given specimen to species-level requires merely combining group-level identification with locality. Importantly, four species groups are not monophyletic: Tricolor Group, Raptor Group, Eastern 4-Plates, and Eastern 2-Plates. This is because these species groups serve to ease identification, not to inform relationship. However, despite the utility of learning these species groups, they are meant to merely augment the key. Accurate identification of most species still requires keying slide preparations under higher magnification (i.e., compound microscope) with precise measurements.

Thirteen species do not fit into species groups. Three of these species are among the most recognizable species in the genus, but are single-species and thus not “groups”: T. arktonyx Fisher & Dowling, sp. n.; T. projector Habeeb, 1961; and T. tahoei (Marshall, 1943). Nine of the 13 species are not placed within a species group because they are difficult to identify under lower magnification and have little in common with sister species. The reader is referred to the key and diagnoses for these species: T. oregonensis Fisher & Dowling, sp. n.; T. wiedenmanni Fisher & Dowling, sp. n.; T. bondi Fisher & Dowling, sp. n.; T. occidentalis (Marshall, 1933); T. raptoroides Fisher & Dowling, sp. n.; T. regalis Fisher & Dowling, sp. n.; T. sharkeyi Fisher & Dowling, sp. n.; T. skvarlai Fisher & Dowling, sp. n.; and T. ventura Habeeb, 1973.

The Rala Group (Figure 79, 11) is the only species group that does not fit within a species complex. This group comprises seven species: T. boettgeri; T. kurtvietsi; T. lamellipalpis; T. keesdavidsi; T. rala; T. dolichodactyla; and T. anoplopalpa. These species are colorless and have incomplete or indistinct hind coxal margins. They are southwestern (Arizona, New Mexico, and Texas), with a few extending into Mexico and Guatemala. However, we suspect all seven species extend well into Mexico and perhaps further south, with US populations representing the northern-most extents of their distributions.

Raptor Complex (Figure 711): Molecular analyses recovered 19 species in this complex. One of these species, T. racupalpa Fisher & Dowling, sp. n., could not be included in the combined dataset, but was included in the COI analysis, where it was recovered as sister to T. elusiva Fisher & Dowling, sp. n. Additionally, fresh material for molecular analysis was not available for five other species suspected as being within this complex based upon morphology: T. danielleae Fisher & Dowling, sp. n.; T. daemon Fisher & Dowling, sp. n.; T. ivyae Fisher & Dowling, sp. n.; T. reduncarostra Fisher & Dowling, sp. n.; and T. dentirostra Fisher & Dowling, sp. n. In total, there are 24 species within the Raptor Complex.

All members of the Raptor Complex are eastern. A collection of western species (T. raptoroides Fisher & Dowling, sp. n.; T. sharkeyi Fisher & Dowling, sp. n.; T. ventura Habeeb, 1973; and the Rala Group) that do not form a monophyletic group, are often recovered as sister to the Raptor Complex. This suggests that the Raptor Complex may have originated from a Neotropical ancestor that dispersed into the eastern US and subsequently diversified. However, this speculation requires worldwide sampling for support.

Basal lineages within the Raptor Complex remain unsupported/unresolved, but a few relationships within the complex were recovered with high support. First, the Erectirostra Group was not recovered as monophyletic in the COI analysis, but is well-supported in the combined analysis. Second, the Neoanomala and Erectirostra Groups are closest relatives; indeed, apart from the apomorphic subcapitulum of the Erectirostra Group, the two groups are otherwise similar. Third, a sister relationship between the Erectirostra + Neoanomala lineage and the Nigroalba Group was recovered with high support. Finally, both analyses support a sister relationship between T. bondi Fisher & Dowling, sp. n. and the Elongata Group.

22 of the 24 species of the Raptor Complex are organized into five species groups: Raptor Group, Elongata Group, Nigroalba Group, Erectirostra Group, and Neoanomala Group. Two species do not fit within an identification group: T. bondi Fisher & Dowling, sp. n. and T. skvarlai Fisher & Dowling, sp. n.

The Raptor Group (Figure 10) comprises ten eastern species: T. danielleae Fisher & Dowling, sp. n.; T. daemon Fisher & Dowling, sp. n.; T. ivyae Fisher & Dowling, sp. n.; T. gnoma Fisher & Dowling, sp. n.; T. irapalpa Fisher & Dowling, sp. n.; T. longitibia Fisher & Dowling, sp. n.; T. mjolniri Fisher & Dowling, sp. n.; T. elusiva Fisher & Dowling, sp. n.; T. racupalpa Fisher & Dowling, sp. n.; and T. raptor Fisher & Dowling, sp. n. These closely related species are readily identifiable with the following combination of characters: round bodies; Dgl-4 close to muscles scars; long thin subcapitular rostra; and long, thin pedipalp tibiae. This group was not recovered as monophyletic in our analyses; however, relationships within this group are also not well-supported, so neither monophyly nor non-monophyly can be rejected.

The Elongata Group (Figure 10) comprises three eastern species: T. elongata Fisher & Dowling, sp. n.; T. reduncarostra Fisher & Dowling, sp. n.; and T. gorti Fisher & Dowling, sp. n. Members of this distinctive group are readily identifiable by the combination of characters: small body size; bold, distinctive coloration; and elongate, ovoid body shape. No other species share this combination of characters. Furthermore, no other Torrenticola have similar coloration to the dark morph of T. gorti and no other Torrenticola are as elongate as T. elongata.

The Nigroalba Group (Figure 11) comprises four eastern species: T. flangipalpa Fisher & Dowling, sp. n.; T. dentirostra Fisher & Dowling, sp. n.; T. nigroalba Habeeb, 1955; and T. solisorta Fisher & Dowling, sp. n. These closely related species are readily identifiable with the following combination of characters: small body size; long, thin subcapitular rostra and pedipalp tibiae; dorsal purple coloration restricted to posterior half; somewhat elongate bodies; and hind coxal margins that are distinctly present, but the margins of are poorly defined. Several western species can superficially resemble members of the Nigroalba Group under low magnification (e.g., T. tahoei and T. regalis).

The Erectirostra Group (Figure 11) comprises three eastern species: T. erectirostra Fisher & Dowling, sp. n.; T. karambita Fisher & Dowling, sp. n.; and T. robisoni Fisher & Dowling, sp. n. These closely related species are readily identifiable with the following combination of characters: thick subcapitular rostra (when viewed ventrally) that is strongly upturned and dentate and Cxgl-4 nearly halfway down gnathosomal bay. No other Torrenticola in North America have similar subcapitular rostra and members of the Erectirostra Group can be readily sorted under low magnification. In terms of body shape and coloration, they superficially resemble Neoanomala Group, to which they are closely related.

The Neoanomala Group (Figure 11) comprises two eastern species: T. interiorensis Fisher & Dowling, sp. n. and T. neoanomala Habeeb, 1957. These closely related species are readily identifiable with the following combination of characters: dorsal coloration often purplish, separated into anterior and posterior portions; hind coxal apodemes distinct; and other characters relatively unmodified. Members of the Neoanomala Group are readily differentiated from the superficially similar Rusetria Group by having distinct hind coxal apodemes, whereas all members of the Rusetria Group have indistinct hind coxal apodemes. Another species—T. bondi Fisher & Dowling, sp. n.—resembles members of this group, but is not closely related. T. bondi have a shorter medial suture (10–15 µm in female T. bondi, 22–40 µm in female Neoanomala Group; 55–70 µm in male T. bondi, 75–110 µm in male Neoanomala Group). Also, T. bondi is currently known only from Haywood County (North Carolina), which implies that this species is either rare, or has a restricted distribution.

Miniforma Complex (Figure 79, 1213): Molecular analyses recovered eight western species in this complex. Additionally, fresh material for molecular analysis was not available for five other species (T. occidentalis (Marshall, 1933); T. miniforma Habeeb, 1974; T. oliveri Fisher & Dowling, sp. n.; T. leviathan Fisher & Dowling, sp. n.; and T. pinocchio Fisher & Dowling, sp. n.) that are suspected to be within this complex based upon morphology. Another species, T. oregonensis Fisher & Dowling, sp. n., superficially resembles members of this complex, but is divergent enough that we avoid placing this species pending molecular support. Therefore, in total, we propose 13 species in this complex.

These species are organized into two monophyletic species groups: Ellipsoidalis Group and Miniforma Group. The two members of this complex that are not placed within a species group include T. tahoei (Marshall, 1943), which is among the most recognizable species of the genus, and T. regalis Fisher & Dowling, sp. n., which can only be confidently identified by keying slide-mounted specimens. Torrenticola tahoei is consistently recovered as sister to the rest of the species in this complex and T. regalis is consistently recovered sister to Ellipsoidalis Group.

The Miniforma Group (Figure 12) comprises seven western species: T. manni Fisher & Dowling, sp. n.; T. oliveri Fisher & Dowling, sp. n.; T. pinocchio Fisher & Dowling, sp. n.; T. miniforma Habeeb, 1974; T. pacificensis Fisher & Dowling, sp. n.; T. rockyensis Fisher & Dowling, sp. n.; and T. copipalpa Fisher & Dowling, sp. n. Members of this group are often readily identified by their smaller body size than other Torrenticola within their range except for Wester 2-Plates (T. mulleni Fisher & Dowling, sp. n.; T. nortoni Fisher & Dowling, sp. n.; T. walteri Fisher & Dowling, sp. n.; and T. welbourni Fisher & Dowling, sp. n.). Members of the Miniforma Group are easily distinguished from Western 2-Plates, which have dorso-lateral platelets fused to the dorsal plate. The Miniforma Group can be further differentiated from all other Torrenticola by their distinctive pedipalp genual extensions. Females of this group have a relatively large genital field, which we suspect coincides with loss of larval parasitism.

The Ellipsoidalis Group (Figure 13) comprises four western species: T. occidentalis (Marshall, 1933); T. ellipsoidalis (Marshall, 1943); T. leviathan Fisher & Dowling, sp. n.; and T. multiforma Habeeb, 1974. Members of this group are readily identified from co-occurring Torrenticola via their larger body size than other species in a given sample. Torrenticola occidentalis may fit within this species group based upon overall similarity and by having a short, conical rostrum, but we were not able to obtain fresh material to confirm this hypothesis.

Rusetria Complex (Figure 79, 1416): Molecular analyses recovered 17 species in this complex. Additionally, fresh material for molecular analysis was not available for nine other species that are included here based upon morphology: T. rufoalba Habeeb, 1955; T. kittatinniana Habeeb, 1955; T. indistincta (Marshall, 1929); T. whitneyae Fisher & Dowling, sp. n.; T. microbiscutella Fisher & Dowling, sp. n.; T. feminellai Fisher & Dowling, sp. n.; T. priapus Fisher & Dowling, sp. n.; T. folkertsae Fisher & Dowling, sp. n.; and T. pulchra Fisher & Dowling, sp. n. In total, there are 26 species in this complex.

Unlike other species complexes, the Rusetria Complex corresponds to a previously recognized subgenus—“Rusetria”—that occurs worldwide and is identified by the fusion of the lateral platelets. Goldschmidt (2007) called species with fused lateral platelets “Rusetria-like species” and we continue that terminology here. However, our analyses indicate that a reversal to free lateral platelets occurred twice: once in a clade sister to the Eastern 2-Plates and once within the Eastern 2-Plates (T. glomerabilis). Members of the Rusetria Complex can also be differentiated from superficially similar species by having indistinct hind coxae (distinct in most similar species, such as the Neoanomala and Raptor Groups). Only a few other species have indistinct hind coxal margins (T. dolichodactyla, T. skvarlai, and occasionally T. flangipalpa) or partial hind coxal margins (T. regalis, T. sharkeyi, and membes of the Nigroalba and Rala Groups,). This character is particularly useful when differentiating Eastern 4-Plates from similar species.

Two interesting evolutionary stories are suggested by the combined molecular analysis. The first involves the fusion of the lateral platelets, which seems to have a complex evolutionary history. For example, if this character is synapomorphic for the Rusetria Complex, then there have been multiple reversals. Furthermore, the position of the Partial 2-Plates suggests that the partial fusion of their lateral platelets represents a transitional step to complete fusion. But this story is even more complicated by T. glomerabilis, which has regained free lateral platelets separately from the rest of the Eastern 4-Plates. Ultimately, understanding the evolution of lateral platelet fusion, even within the eastern U.S., will depend on a much greater sampling of this worldwide species complex. Second, significant sexual size dimorphism (i.e., males 20–30% smaller than females), which is found in most members of this complex worldwide, likely arose once within the complex basally, but was subsequently and independently lost (i.e., males 5–15% smaller than females) three times: twice within the Eastern 4-Plates (once with the sister species T. dunni Fisher & Dowling, sp. n. and T. pollani Fisher & Dowling, sp. n., and once with T. glomerabilis Fisher & Dowling, sp. n.) and once with T. ululata Fisher & Dowling, sp. n.

The 23 species of the Rusetria Complex are organized into four species groups: Eastern 4-Plates, Eastern 2-Plates, Partial 2-Plates, and Western 2-Plates.

The Eastern 2-Plate Group (Figure 1415) comprises 12 eastern species: T. biscutella Fisher & Dowling, sp. n.; T. whitneyae Fisher & Dowling, sp. n.; T. microbiscutella Fisher & Dowling, sp. n.; T. feminellai Fisher & Dowling, sp. n.; T. caerulea Fisher & Dowling, sp. n.; T. delicatexa Habeeb, 1955; T. indistincta (Marshall, 1929); T. malarkeyorum Fisher & Dowling, sp. n.; T. pendula Fisher & Dowling, sp. n.; T. sellersorum Fisher & Dowling, sp. n.; T. tysoni Fisher & Dowling, sp. n.; and T. ululata Fisher & Dowling, sp. n. This group is not monophyletic because of the exclusion of T. glomerabilis Fisher & Dowling, sp. n., which is considered an Eastern 4-Plate based on morphology. Members of this group are readily identifiable by having dorso-lateral platelets fused with the dorsal plate, thus giving the appearance of having only two plates, the anterio-medial platelets. Most members of this group are colorful (except for T. indistincta, which resembles Western 2-Plates) and nearly all have similar dorsal patterns that are separated into anterior and posterior portions, which are occasionally connected medially (except T. ululata, Figures 262263). Members of the Eastern 2-Plate group are similar to the western counterpart (below) in having fused lateral platelets. However, the majority of eastern species are distinctly more colorful than most western species, which are either colorless or only faintly colored, and the groups exhibit non-overlapping ranges.

The Western 2-Plate Group (Figure 16) comprises four western species: T. mulleni Fisher & Dowling, sp. n.; T. nortoni Fisher & Dowling, sp. n.; T. walteri Fisher & Dowling, sp. n.; and T. welbourni Fisher & Dowling, sp. n. Members of this group are readily identifiable by having dorso-lateral platelets fused with the dorsal plate, thus giving the appearance of having only two plates. Although resembling Eastern 2-Plates, ranges are non-overlapping and western species are immediately identifiable by being colorless or nearly so, whereas most eastern species (except T. indistincta) are colorful. Besides range information, Torrenticola indistincta can be differentiated from Western 2-Plates by having coxal apodemes I-II not meeting posteriorly (meeting in western-two plates, usually with an accompanying medial suture).

The Partial 2-Plate Group (Figure 15) comprises four eastern species: T. priapus Fisher & Dowling, sp. n.; T. folkertsae Fisher & Dowling, sp. n.; T. pulchra Fisher & Dowling, sp. n.; and T. magnexa Habeeb, 1955. These species are readily distinguished from all other Torrenticola by having dorso-lateral platelets only partially fused to the dorsal plate. In practice, when sorting under low magnification (i.e., stereoscope), this group appears to be Eastern 2-Plates, but closer inspection will show that the lateral platelet borders are distinct, even under low magnification. This group will likely not be confused with members of the Rusetria 4-Plates (below), as the latter do not appear to have lateral plate fusion, even under low magnification.

The Eastern 4-Plate Group (Figure 15) comprises six eastern species: T. dunni Fisher & Dowling, sp. n.; T. glomerabilis Fisher & Dowling, sp. n.; T. kittatinniana Habeeb,1955; T. pollani Fisher & Dowling, sp. n.; T. rufoalba Habeeb, 1955; and T. shubini Fisher & Dowling, sp. n. This group is not monophyletic because T. glomerabilis is more closely related to Eastern 2-Plates. Members of this group can be readily differentiated from all other species of the Rusetria Complex by having anterio-lateral platelets completely free from the dorsal plate, hence “4-Plates”. All members of this group are colorful and have similar dorsal patterns that are separated into anterior and posterior portions and occasionally connected medially. Members of this group resemble the Neoanomala Group in overall appearance and coloration; however, they can be readily differentiated by having indistinct hind coxal margins (distinct in Neoanomala Group). Members of this group also resemble T. skvarlai in terms of overall appearance and coloration, and in having indistinct hind coxal margins; however, they can be readily differentiated by having conical, tuberculate pedipalp femoral extensions (broadly tuberculate in T. skvarlai).

Tricolor Complex (Figure 79, 1718): Molecular analyses recovered 10 species in this complex. Fresh material for molecular analysis was not available for four other species (T. bittikoferae Crowell, 1960; T. cardia Fisher & Dowling, sp. n.; T. kringi Fisher & Dowling, sp. n.; and T. mohawk Fisher & Dowling, sp. n.) that are grouped within this complex based upon morphology. In total, there are 14 species within the Tricolor Complex.

Figure 17. 

Tricolor Complex (part I). All species are eastern. These are some of the most recognizable of all Torrenticola, namely the elongate T. projector and a clade of species with diagnostic color patterns (T. trimaculata, T. unimaculata, and T. tricolor). Note that three species (T. pearsoni, T. hoosieri, and T. projector) are repeated in Figure 18.

This complex is divided into eastern and western lineages. The eastern lineage contains species that are among the most distinctive of all Torrenticola (e.g., T. trimaculata Fisher, 2015; T. dimorpha Fisher & Dowling, sp. n.; and T. projector Habeeb, 1961). This complex contains one species group, the Tricolor Group, which is paraphyletic with respect to T. projector. This species has an elongate morphology that is unique among species of the Tricolor Complex.

The Tricolor Group (Figure 1718) comprises 13 species: T. bittikoferae Crowell, 1960; T. cardia Fisher & Dowling, sp. n.; T. kringi Fisher & Dowling, sp. n.; T. dimorpha Fisher & Dowling, sp. n.; T. mohawk Fisher & Dowling, sp. n.; T. hoosieri Fisher & Dowling, sp. n.; T. larvata Cherri, Fisher, & Dowling, 2016; T. olliei Fisher & Dowling, sp. n.; T. pearsoni Fisher & Dowling, sp. n.; T. projector Habeeb, 1961; T. sierrensis (Marshall, 1943); T. tricolor Habeeb, 1957; T. trimaculata Fisher, 2015; and T. unimaculata Fisher & Dowling, sp. n. Most species are distributed in eastern North America, except for T. sierrensis and T. olliei, which are western. The most distinguishing characteristic of this group is a short, conical rostrum, which is noticeably downturned in males. The only exception is T. kringi, which has a conical rostrum that is longer than other members of the group. Five members of the Tricolor Group form a monophyletic subgroup and can be readily recognized by having dorsal coloration composed of one or more spots (T. kringi, T. mohawk, T. tricolor, T. trimaculata, T. unimaculata). The Tricolor Group also contains a morphologically enigmatic species that has strong sexual dimorphism: T. dimorpha. Finally, T. bittikoferae likely fits within this complex, but fresh material was not available to test this hypothesis.

Biogeography

Of the 90 species discussed herein, 57 are primarily eastern (east of the 100th Meridian) and 33 are western (west of the 100th Meridian). Only a few species are distributed on either side of this barrier: T. irapalpa is widespread in the east and has populations in Saskatchewan; T. rala is widespread from Costa Rica to Arizona and is also found in south-central Texas; and T. sellersorum has a widespread, but sporadic, distribution spanning Arizona to Manitoba and Ohio to Pennsylvania. Aside from these few species, the Great Plains acts as a biogeographic barrier for most species and Torrenticola are not common within this region.

Much of the discrepancy between the eastern and western diversity is due to increased diversity in the Appalachians, particularly due to increased speciation within the Raptor and Rusetria Complexes, which have 17 (14 endemic) and 15 (12 endemic) species found in the Appalachians, respectively. The Southern Appalachian region is particularly diverse, with 14 endemics (T. arktonyx, T. bondi, T. karambita, T. longitibia, T. danielleae, T. daemon, T. dentirostra, T. racupalpa, T. dunni, T. glomerabilis, T. whitneyae, T. microbiscutella, T. feminellai, and T. pollani). The Northern Appalachian region contains six species known only from that area (T. elusiva, T. kittatinniana, T. folkertsae, T. pendula, T. rufoalba, and T. mohawk); however, two of these are known only from their type localities in northern New Jersey (T. kittatinniana and T. rufoalba). Eight species are restricted to the Appalachians, but range throughout both northern and southern regions (T. erectirostra, T. gorti, T. reduncarostra, T. skvarlai, T. delicatexa, T. shubini, T. cardia, T. projector). Three species appear to be widespread in the northeast (i.e., extending into the Great Lakes region in Ottawa), but also extend southward throughout the Appalachians (T. nigroalba, T. raptor, and T. tricolor). The remaining eastern diversity includes seven widespread species (T. malarkeyorum, T. trimaculata, T. irapalpa, T. neoanomala, T. magnexa, T. priapus, and T. sellersorum); seven species endemic to the Interior Highlands (T. biscutella, T. interiorensis, T. robisoni, T. solisorta, T. larvata, T. pearsoni, and T. unimaculata); six species from the non-mountainous southeast (T. caerulea, T. elongata, T. flangipalpa, T. gnoma, T. tysoni, and T. ululata); four species known only from the Midwest (T. bittikoferae, T. indistincta, T. hoosieri, and T. pulchra); one species from Florida (T. ivyae); and one species from eastern Texas (T. kringi).

Our results point to two eastern regions that have high diversity and an increased proportion of endemic species: the southern Appalachians (including southern Pennsylvania) and the Interior Highlands (Ozarks and Ouachitas of Missouri, Arkansas, and Oklahoma). Of the 31 species known from the southern Appalachians, 14 are endemic. Of the 13 species known from the Interior Highlands, seven are endemic. Each of these regions is well-known for its diversity and endemism of aquatic taxa, due to a complex biogeographic history where they have acted as refugia (Robison & Allen 1995; Radwell et al. 2011; Skvarla et al. 2015).

By contrast, western Torrenticola are less diverse, with 32 species known from the region. Four species are widespread (T. ellipsoidalis, T. multiforma, T. sierrensis, and T. tahoei), although only one of these, T. multiforma, is also found in the southwest. Two species are found throughout much of California (T. nortoni and T. ventura) with only T. ventura extending northward into southwestern Oregon. One species is known from south-central Texas (T. dimorpha). The remaining western diversity is distributed into patterns that roughly correspond to three major ecoregions: Rocky Mountains, Pacific Ranges, and the arid southwest. The Rockies contain three endemics (T. occidentalis, T. rockyensis, and T. mulleni). The Pacific Ranges of British Columbia, Washington, Oregon, and northern California contain nine endemics (T. miniforma, T. oregonensis, T. oliveri, T. leviathan, T. pinocchio, T. pacificensis, T. regalis, T. welbourni, and T. olliei), and two species that also range into the Sierra Nevada (T. copipalpa and T. walteri), although the latter (T. walteri) is also known from one locality in the Rockies of southern British Columbia. The arid southwest (southern California, Arizona, and New Mexico) contains eleven species restricted to that region in the US (T. boettgeri, T. keesdavidsi, T. kurtvietsi, T. lamellipalpis, T. dolichodactyla, T. anoplopalpa, T. raptoroides, T. sharkeyi, T. wiedenmanni, and T. rala), although five of these extend southward into Mexico and Central America (T. boettgeri, T. keesdavidsi, T. kurtvietsi, T. lamellipalpis, and T. rala) and one is also found in southern Texas (T. rala).

Our results suggest the diversity of Torrenticola in eastern North America can be explained by as few as three dispersal events, followed by subsequent radiations (Figure 8). Western diversity is more complex and was likely influenced from southern species extending northward and also by northern species that crossed Beringia and extended southward. However, even these results are speculative, pending worldwide sampling.

The distributions described above show the variable dispersal capabilities of different species within the genus. For instance, some species are wide-ranging, with distributions that span multiple topographic barriers (e.g., T. irapalpa, T. multiforma, and T. ellipsoidalis), whereas other groups are endemic to specific geographic areas and so are not able to cross such barriers (e.g., T. pacificensis, T. rockyensis, T. arktonyx, and T. solisorta). To explain this variation, adequate knowledge of the dispersal capabilities of both the adult and larval stages is required.

It seems well-understood that water mite larvae utilize the dispersal capabilities of their winged insect hosts. Indeed, it is normally inferred that dispersal is the primary function of the parasitic larvae, as is exemplified by the following passage from Proctor et al. (2015, pg. 639):

“The dominant strategic role of the larval instar in the life history of most Hydryphantoidea, Lebertioidea, Hygrobatoidea, and Arrenuroidea appears to be dispersal rather than growth. Species that have the parasitic larval stage suppressed illustrate that development of large eggs can obviate the need for larval feeding. However, the relative rarity of this phenomenon attests to the crucial role of larval dispersal in more derived water mite species.”

Consistent with this view, many lentic water mites utilize far-flying hosts such as dragonflies (e.g., Arrenurus), various true bugs (e.g., Hydrachna), and beetles (e.g., Eylais) (Proctor et al. 2015). However, if Torrenticola were utilizing such hosts, we would expect fewer instances of endemism, as well as more dispersal events across the east-west divide. Instead, all eastern Torrenticola diversity could be explained by as little as three dispersal events. We speculate that this pattern can be explained by Torrenticola larval ecology. Torrenticola, like most lotic water mites, parasitize nematocerous flies, especially Chironomidae. Torrenticola are reported from the thoraces (rarely abdomen) of three chironomid subfamilies and ten genera: Tanypodinae (1 genus), Orthocladiinae (6 genera), and Chironominae (3 genera) (Smith & Oliver 1976, 1986). In the proper habitat (clean fast-flowing streams and riffles), Torrenticola adults are typically far more abundant than other water mites and larvae are easily identified by possessing fused coxal plates (unlike all other Lebertioidea [Smith 1982]), which should increase both the likelihood of larvae being sampled on a host and being identified by researchers. However, larval Torrenticola are rarely reported. Unfortunately, Torrenticola larvae are not currently correlated with adults, so there is no way to link species to hosts and we can only conclude that at least some unidentified species parasitize chironomids.

This lack of knowledge has important ramifications because chironomids appear to have different inter- and intra-species natal fidelity. Although only a few studies have addressed adult chironomid dispersal (e.g., Delettre and Morvan 2000, Krosch et al. 2011), they suggest that the propensity for adult chironomids to disperse decreases when the natal stream is bordered by dense vegetation, which appears to confine them to the stream from which they emerged. This trend is not restricted to chironomids as other aquatic insects that inhabit flowing water are also unable to disperse through dense riparian vegetation (Titmus 1980, Jackson and Resh 1989, Peterson et al. 1999, Delettre and Morvan 2000). Conversely, in areas with low vegetation, chironomids have been shown to disperse further (Delettre and Morvan 2000), and under such conditions can even cross into nearby catchments (Krosch et al. 2011).

We speculate that broadly distributed water mite species (e.g., T. ellipsoidalis, T. multiforma, T. sierrensis, T. tahoei, T. malarkeyorum, T. trimaculata, T. irapalpa, T. neoanomala, T. magnexa, T. priapus, and T. sellersorum) disperse primarily during the larval stage by utilizing chironomids with low natal fidelity, whereas species that are confined to a smaller geographic region (e.g., T. solisorta, T. larvata, T. pacificensis, T. rockyensis, T. arktonyx) either utilize chironomids that have high natal fidelity, or they have lost parasitism altogether. As discussed previously, loss of parasitism is especially likely with members of the Miniforma Group, which in addition to high endemism, also possess characters that have been proposed for species that have lost parasitism, such as smaller body size and a larger female genital opening (Smith 1998). In either case (host natal fidelity or loss of parasitism), the result is that species confined to a smaller geographic region may be more dependent on the adult stage for dispersal. A sound understanding of Torrenticola larval ecology, including host associations, is critical to understanding the biology of the genus. Unfortunately, this area of inquiry is inhibited by our limited understanding, not only of water mites, but also chironomids, which are also understudied in North America, leaving most aspects of the biology of nearly all species involved a mystery.

To fully understand the evolution of Torrenticola within North America, analyses are needed that include worldwide taxon sampling and robust analyses of multiple genes, as well as a comprehensive understanding of larval ecology. To this end, we recommend the following areas of study for future investigation in North America: 1) surveys that correlate larval and adult chironomids; 2) dispersal studies on lotic chironomids; 3) surveys that correlate larval and adult water mites; and 4) surveys that investigate host specificity (i.e., identify both water mite larvae on hosts as well as the species of the hosts).

Diagnosis

Torrenticola anoplopalpa are similar to other members of the Rala Group (T. boettgeri, T. dolichodactyla, T. kurtvietsi, T. keesdavidsi, T. lamellipalpis, and T. rala) by being colorless, having incomplete hind coxal margins and being distributed in the southwest. Torrenticola anoplopalpa can be differentiated from all other Rala Group by having a more elongate subcapitulum (ventral length/width ♂ = 4.16 in T. anoplopalpa, 2.04–3.56 in others). Additionally, T. anoplopalpa can be differentiated from all other Rala Group by femur/genu (♂ 1.94 in T. anoplopalpa, 0.98–1.86 in others), except T. keesdavidsi (1.84–1.96).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola anoplopalpa and so this species is not included in our phylogenetic analyses. However, we were able to examine material preserved in GAW for morphology.

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 1 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola biscutella are similar to other members of the Rusetria “Eastern 2-Plates” group (T. caerulea, T. delicatexa, T. feminellai, T. indistincta, T. malarkeyorum, T. microbiscutella, T. pendula, T. sellersorum, T. tysoni, T. ululata, and T. whitneyae) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. indistincta and T. ululata), and being distributed in the east. It is one of only four Eastern 2-Plates that have dark, bold, bluish-purple coloration (also T. pendula, T. sellersorum, and T. tysoni). Torrenticola biscutella can be differentiated from T. caerulea, T. ululata, T. indistincta, and T. feminellai by dorsal coloration and pattern. T. biscutella can be differentiated from T. tysoni by having a stockier rostrum (length/width = 2.55–2.83 in T. biscutella, 3.06–3.50 in T. tysoni). Female T. biscutella can be differentiated from female T. malarkeyorum by having a shorter subcapitulum (ventral length = 290–315 in T. biscutella, 317.5–335 in T. malarkeyorum). Male T. biscutella can be differentiated from male T. malarkeyorum by having a slightly rounder dorsum (length/width 1.37–1.42 in T. biscutella, 1.42–1.56 in T. malarkeyorum). Additionally, although T. biscutella and T. malarkeyorum have the same dorsal coloration and pattern, often the coloration is bold in T. biscutella and faint in T. malarkeyorum. Female T. biscutella can be differentiated from female T. delicatexa by having a shorter genital field (152.5–167.5 in T. biscutella, 175–198 in T. delicatexa) and male T. biscutella can be differentiated from male T. delicatexa by having a slightly rounder dorsum (length/width = 1.37–1.42 in T. biscutella, 1.44–1.56 in T. delicatexa). Female T. biscutella can be differentiated from female T. sellersorum by anterior venter/genital field length (0.82–0.88 in T. biscutella, 0.69–0.77 in T. sellersorum). Male T. biscutella can be differentiated from male T. sellersorum by having slightly stockier anterio-lateral platelets (length/width = 2.58–2.74 in T. biscutella, 2.76–3.00 in T. sellersorum). T. biscutella can be differentiated from T. pendula by having a stockier gnathosomal bay (1.55–1.85 in T. biscutella, 2.42–2.9 in T. pendula); more elongate tibiae (3.11–3.45 in T. biscutella, 2.78–3.05 in T. biscutella); and by dorsal pattern. T. biscutella can be differentiated from T. microbiscutella by having a more ovoid dorsum (length/width = 1.33–1.42 in T. biscutella, 1.63–1.75 in T. microbiscutella) and by anterior venter/genital field width (♀ = 0.84–0.91 in T. biscutella, 1.25–1.33 in T. microbiscutella; ♂ = 1.68–1.80 in T. biscutella and 1.95–2.29 in T. microbiscutella). T. biscutella can be differentiated from T. whitneyae by having more elongate pedipalpal tibiae (3.11–3.45 in T. biscutella, 2.42–2.95 in T. whitneyae) and by anterior venter/genital field length (♀ = 0.82–0.88 in T. biscutella, 0.59–0.75 in T. whitneyae; ♂ = 1.55–1.76 in T. biscutella and 1.37–1.43 in T. whitneyae).

Etymology

Specific epithet (biscutella) refers to the appearance of only two anterio-dorsal platelets due to the fusion of lateral platelets with the dorsal shield (bi-, L. two; scutella, L. little plate).

Distribution

Interior Highlands (both Ozarks and Ouachitas), likely endemic (Figure 24).

Remarks

Torrenticola biscutella groups with other members of the Rusetria Complex with high support and specimens of this species were less than 2% different in COI sequence from each other. In all analyses, T. biscutella groups with two other morphologically similar species: T. malarkeyorum and T. caerulea. These three species are 3–5% different from each other in COI sequence. The three of these species are morphologically similar to the more distantly-related T. delicatexa. Of these four species, the range of T. biscutella only overlaps with T. malarkeyorum in the Ozark Mountains and these species are easily differentiated by color. T. biscutella is the only one of these four species known from the Ouachita Mountains, and it is not known from east of the Mississippi River, where the other three species are distributed (only T. malarkeyorum is known from west of the Mississippi River).

Based upon overall similarity, dorso-lateral platelet fusion, and distribution, we were able to place this species within the Eastern 2-Plate Identification Group.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by morphological characters outlined in the diagnoses.

Torrenticola bittikoferae Crowell, 1960

T. bittikoferae : Crowell 1960: 36; 1961: 330 • Johnston 1965: 44 • Modlin and Gannon 1973: 219, 221 • Viets 1987: 756.

Material examined

PARATYPES (0 ♀; 2 ♂): Ohio, USA: 2 ♂ from Ottawa County, Middle Bass Island, rubble beach, 29 June 1954, by R Crowell.

Type deposition

Holotype (♀) and some paratypes (unspecified number) deposited in the Chicago Natural History Museum (unexamined; types not located); other paratypes (2 ♂) deposited in the OSUAC.

Diagnosis

Torrenticola bittikoferae are similar to other members of the Tricolor Group (T. cardia, T. dimorpha, T. hoosieri, T. kringi, T. larvata, T. mohawk, T. olliei, T. pearsoni, T. sierrensis, T. tricolor, T. trimaculata, and T. unimaculata) in having a short, conical rostrum. Torrenticola bittikoferae can be differentiated from most other Tricolor Complex (except T. hoosieri, T. pearsoni, and T. dimorpha) by being colorless, whereas most other members have bold patterning. T. bittikoferae can be differentiated from T. hoosieri by having ventral extensions on the pedipalp femora and genua (lacking in T. hoosieri) and having stockier pedipalp tibiae (length/width = 2.7–2.8 in T. bittikoferae, 3.6–4.4 in T. hoosieri). T. bittikoferae can be differentiated from T. pearsoni by having Dgl-4 further from the dorsal edge (dorsal width/distance between Dgl-4 = 1.6–1.7 in T. bittikoferae, 1.2–1.3 in T. pearsoni); stockier pedipalp tibiae (length/width = 2.7–2.8 in T. bittikoferae, 3.0–3.3 in T. pearsoni); and a more elongate rostrum (length/width = 1.8–1.9 in T. bittikoferae, 2.0–2.4 in T. pearsoni). Torrenticola bittikoferae can be differentiated from T. dimorpha by having an unmodified dorsal plate (T. dimorpha has a dorsal plate medial extension covering nearly half the length of the anterio-medial platelets) and by males having unmodified pedipalps (male T. dimorpha have large, highly modified pedipalps which are expanded vertically and laterally).

Etymology

Robert Crowell (1960) named the specific epithet (bittikoferae) after Lelia Bittikofer, his high school biology teacher.

Distribution

Known only from type locality: Lake Erie, Ohio (Figure 27).

Remarks

Unfortunately, we were unable to acquire fresh specimens of Torrenticola bittikoferae and therefore this species was not included in our phylogenetic analyses. We were able to examine paratypes of two males, neither of which were dissected during slide preparation, making precise examination difficult. These specimens were remounted, but proper dissection risked fully damaging the specimen and was therefore avoided. The images in Figure 28A–B that appear to display a properly dissected specimen, were created by photographing each section (dorsum and venter) of the fully intact specimen and digitally editing the photographs so that the dorsum and venter could be easily compared with other species.

The overall appearance, short conical rostrum, and distribution of this species allows us to places it within the Tricolor Complex and Tricolor Identification Group.

T. boettgeri can be differentiated from all other Rala Group by having a more elongate dorsum (length/width ♀ = 1.74–1.82 in T. boettgeri, 1.21–1.60 in others) and a stockier subcapitulum (ventral length/width = 1.96 in T. boettgeri, 2.06–3.52 in others; ♂ = 2.04–2.07 in T. boettgeri, 2.14–4.16 in others).

Etymology

Viets (1977a) named the specific epithet (boettgeri) in honor of Klaus Böttger of the University of Kiel, Germany, who collected the type specimen in Rio Chilax near Cobán, Guatemala.

Distribution

New Mexico (probably also Arizona) and extending southward into Mexico and Guatemala (Figure 29).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola boettgeri and therefore this species is not included in our phylogenetic analyses. We were also unable to examine types, but were able to examine new material from New Mexico. The overall appearance, incomplete hind coxal margins, distribution, and lack of coloration are consistent with placing this species in the Rala Identification Group.

Viets (1977a) described T. boettgeri from a single female collected in Guatemala. Cramer (1992) described T. esbelta from three females collected in one stream (Peña Blanca) in San Francisco Oxtotilpan, State of Mexico, Mexico. Cramer (1992) differentiated T. esbelta from T. boettgeri by pedipalpal tibia length: 36 µm in T. esbelta; 26-27 µm (right, left, respectively). Given our experience with the variability of tibial length across species, which often range well over 10 µm, and especially considering the very few number of specimens examined, we do not consider slight variations in pedipalp tibial length to be good evidence for separate species. Furthermore, our material from New Mexico includes specimens with tibiae in between the previously recorded specimens (32.5 µm in our single female specimen; 32.5–37.7 µm in males). Therefore, we consider T. esbelta as a junior synonym of T. boettgeri.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola bondi are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba, and T. shubini), Elongata Group (T. elongata, T. gorti, and T. reduncarostra), Neoanomala Group (T. interiorensis and T. neoanomala), and T. erectirostra, T. robisoni, T. irapalpa, T. racupalpa, T. skvarlai, and T. arktonyx. They can be differentiated from Rusetria 4-Plates and T. skvarlai by having distinct hind coxal margins. T. bondi can be differentiated from T. erectirostra and T. robisoni by having a straight, anteriorly-directed rostrum (upturned in others). T. bondi can be differentiated from T. arktonyx by having an unmodified dorsal plate (T. arktonyx has distinctive longitudinal dark markings on the anterior portion of the dorsal plate that fade posteriorly). T. bondi can be differentiated from T. racupalpa and T. irapalpa by having a more ovoid dorsum (dorsum length/width ♀ = 1.35–1.41 in T. bondi, 1.17–1.28 in others; ♂ = 1.32–1.45 in T. bondi, 1.20–1.30 in others) and shorter pedipalpal tibiae (♀ = 90–98 in T. bondi, 100–125 in others, ♂ = 77–83 in T. bondi, 87–110 in others). T. bondi can be differentiated from the Elongata Group by having a less elongate dorsum (length/width ♀ = 1.35–1.41 in T. bondi, 1.45–2.08 in Elongata Group; ♂ = 1.32–1.45 in T. bondi, 1.51–1.70 in Elongata Group) and having a stockier rostrum (length/width = 2.76–3.13 in T. bondi, 3.24–4.00 in Elongata Group). T. bondi can be differentiated from the Neoanomala Group by having a shorter medial suture (♀ = 10–15 in T. bondi, 22–40 in Neoanomala Group; ♂ = 55–70 in T. bondi, 75–108 in Neoanomala Group) and anterior venter/genital field width (♀ = 1.15–1.25 in T. bondi, 1.31–1.45 in Neoanomala Group; ♂ = 1.95–2.05 in T. bondi, 2.09–2.66 in Neoanomala Group).

Etymology

Specific epithet (bondi) named in honor of arachnologist Jason Bond, for his research on species delimitation and integrative taxonomy, which has been an inspiration to JRF, and for his thoughtful career advice, which was greatly appreciated.

Distribution

Known only from Great Smoky Mountains National Park, Haywood County, North Carolina (Figure 32).

Remarks

Torrenticola bondi groups with other members of the Raptor Complex in all analyses with high support. Only one specimen could be acquired for use in our analyses, so differences in COI sequence across specimens could not be investigated, but this single specimen was greater than 5% different in COI sequence from sister species. In all analyses, T. bondi grouped with members of the Elongata Identification Group (T. elongata and T. gorti). However, the position of this clade varied with analysis.

This species hypothesis is supported by high divergence between species (3–15%) and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (3 ♀; 1 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola caerulea are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. delicatexa, T. feminellai, T. indistincta, T. malarkeyorum, T. microbiscutella, T. pendula, T. sellersorum, T. tysoni, T. ululata, and T. whitneyae) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. T. caerulea can be differentiated from all other Eastern 2-Plates by having faint blue coloration. T. caerulea can be differentiated from T. ululata and T. feminellai by dorsal coloration and pattern. T. caerulea can be differentiated from T. tysoni by having a less elongate rostrum (length/width = 2.67–2.96 in T. caerulea, 3.06–3.50 in T. tysoni). T. caerulea can be differentiated from T. pendula by having a more elongate gnathosomal bay (1.40–2.09 in T. caerulea, 2.42–2.90 in T. pendula) and more elongate pedipalpal tibiae (3.11–3.83 in T. caerulea, 2.78–3.05 in T. pendula). T. caerulea can be differentiated from T. microbiscutella by having a less elongate dorsum (length/width = 1.32–1.56 in T. caerulea, 1.63–1.75 in T. microbiscutella). T. caerulea can be differentiated from T. whitneyae by having more elongate pedipalpal tibiae (length/width = 3.11–3.83 in T. caerulea, 2.42–2.95 in T. whitneyae) and by anterior venter/genital field width (♀ = 0.9–1.04 in T. caerulea, 0.67–0.80 in T. whitneyae; ♂ = 1.71–1.83 in T. caerulea, 1.5–1.54 in T. whitneyae). Female T. caerulea can be differentiated from female T. biscutella by having slightly more elongate pedipalpal tibae (length/width = 3.5–3.83 in T. caerulea, 3.35–3.45 in T. biscutella). Male T. caerulea can be differentiated from male T. biscutella by anterior venter/medial suture (2.4–2.57 in T. caerulea, 2.68–2.83 in T. biscutella). Female T. caerulea can be differentiated from female T. malarkeyorum, T. sellersorum, T. delicatexa, and T. indistincta by having a thinner genital field (120–145 in T. caerulea, 150–205 in others). Male T. caerulea can be differentiated from male T. indistincta by having a smaller dorsum (length = 405–460 in T. caerulea, 480–645 in T. indistincta; width = 260–305 in T. caerulea, 315–470 in T. indistincta). Body proportions of male T. caerulea do not differ from male T. malarkeyorum, T. sellersorum, and T. delicatexa, but can be differentiated by dorsal coloration.

Etymology

Specific epithet (caerulea) refers to the overall and diagnostic bluish appearance of this species (caeruleus, L. sky-blue).

Distribution

Known only from Wayne County, Tennessee (Figure 35). T. caerulea has been collected so rarely that comments about distribution are speculative, but given our collection efforts, it is reasonable to speculate that this species is at least restricted to the southern Appalachians.

Remarks

Torrenticola caerulea groups with other members of the Rusetria Complex with high support and specimens of this species were less than 1% different in COI sequence from each other. In all analyses, T. caerulea groups with two other morphologically similar species: T. biscutella and T. malarkeyorum. These three species are 3–5% different from each other in COI sequence. The three of these species are morphologically similar to the more distantly-related T. delicatexa, but T. caerulea can be differentiated from all of these by color. The range of T. caerulea overlaps with each of these except for T. biscutella, which is not known from east of the Mississippi River.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (5 ♀; 4 ♂) deposited in the CNC; other paratypes (4 ♀; 3 ♂) deposited in the ACUA.

Diagnosis

Torrenticola cardia are similar to other members of the Tricolor Complex (T. bittikoferae, T. dimorpha, T. hoosieri, T. kringi, T. larvata, T. mohawk, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, and T. unimaculata,) in having a short, conical rostrum. T. cardia can be differentiated from most Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern. T. cardia are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. tricolor, T. unimaculata, T. trimaculata, T. kringi, and T. mohawk). T. cardia can be differentiated from T. tricolor, T. trimaculata, T. kringi, and T. mohawk by having a more ovoid dorsum (length/width ♀ = 1.39–1.47 in T. cardia, 1.15–1.35 in others; ♂ = 1.43–1.54 in T. cardia, 1.19–1.39 in others). T. cardia can be differentiated from T. unimaculata by dorsal pattern. Female T. cardia can be differentiated from female T. larvata by having a shorter subcapitulum (♀ = 265–273 in T. cardia, 275–288 in T. larvata) and a larger genital field (length ♀ = 190–198 in T. cardia, 182–188 in T. larvata; width ♀ = 160–175 in T. cardia, 145–153 in T. larvata). Male T. cardia can be differentiated from male T. larvata by having less elongate pedipalpal tibiae (length/width ♂ = 2.82–3.05 in T. cardia, 3.10–3.20 in T. larvata) and a larger dorsum (length ♂ = 625–670 in T. cardia, 550–610 in T. larvata; width ♂ = 405–445 in T. cardia, 350–400 in T. larvata).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola cardia and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, short conical rostrum that is downturned in the male, and distribution, are consistent with placing this species in the Tricolor Complex and Tricolor Identification Group.

Type deposition

Holotype (♀), allotype (♂), and other paratypes (15 ♀; 20 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola copipalpa are similar to members of the Miniforma group (T. manni, T. miniforma, T. oliveri, T. pacificensis, T. pinocchio, and T. rockyensis) in having short, stocky pedipalps (except T. oliveri and T. pinocchio); similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. copipalpa are best differentiated from all other Miniforma group (except T. pinocchio) by having broad, flat pedipalp femoral tubercles (conical/tuberculate in all others). T. copipalpa can be differentiated from T. pinocchio by having a less elongate rostrum (length/width = 2.5–3.0 in T. copipalpa, 4.5–4.9 in T. pinocchio) and less elongate pedipalpal tibiae (length/width = 2.4–2.9 in T. copipalpa, 3.1–3.5 in T. pinocchio).

Etymology

Specific epithet (copipalpa) refers to the blade-like pedipalp femoral tubercles (copis, L. small knife; palpus, L. hand, feeler), which distinguish them from similar, co-occurring species.

Distribution

Northern California and western Oregon (Figure 41).

Remarks

Torrenticola copipalpa groups with other members of the Miniforma Complex with high support and specimens of this species are less than 1% different in COI sequence from each other. In all analyses, T. copipalpa groups with three other morphologically similar species: T. pacificensis, T. manni, and T. rockyensis. These three species are greater than 4% different from each other. This species overlaps with T. miniforma in California and with T. pacificensis in west-central Oregon.

Based upon overall similarity, the pedipalp genu extensions, and western distribution, we were able to place this species in the Miniforma Identification Group.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola daemon are similar to other members of the Raptor Group (T. danielleae, T. elusiva, T. gnoma, T. irapalpa, T. ivyae, T. longitibia, T. mjolniri, T. racupalpa, and T. raptor) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. daemon can be differentiated from all other Raptor Group by having Dgl-4 closer to the edge of the dorsum (dorsum width/distance between Dgl-4 ♀ = 1.59–1.67 in T. daemon, 1.80–3.29 in others; ♂ = 1.45–1.65 in T. daemon, 1.66–2.73 in others), except T. irapalpa (♀ = 1.81–2.09, ♂ = 1.58–1.86) and T. danielleae (♀ = 1.57–1.70, ♂ = 1.42–1.52). T. daemon can be differentiated from T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, T. raptor, T. danielleae, and T. ivyae by having a less elongate rostrum (length/width = 2.91–3.31 in T. daemon, 3.43–4.40 in others). Female T. daemon can be differentiated from female T. irapalpa by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 ♀ = 1.59–1.67 in T. daemon, 1.81–2.09 in T. irapalpa) and a more elongate gnathosomal bay (length/width ♀ = 1.95–2.42 in T. daemon, 1.35–1.86 in T. irapalpa). Additionally, T. daemon can be differentiated from T. irapalpa by dorsal coloration and pattern.

Etymology

Specific epithet (daemon) refers to the diagnostic red coloration on the anterio-medial platelets, which resemble the red eyes of an evil demon (daemon, L. originally benevolent or benign nature spirits, but were characterized as dangerous or evil by the writings of Plato and later used in Christian literature, popularizing the idea of demons as evil; noun in apposition).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola daemon and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, elongate subcapitular rostra, elongate pedipalpal tibiae, and Dgl-4 close to the muscle scars, are consistent with placing this species in the Raptor Complex and Raptor Identification Group.

Diagnosis

Torrenticola danielleae are similar to other members of the Raptor Group (T. daemon, T. elusiva, T. gnoma, T. irapalpa, T. ivyae, T. longitibia, T. mjolniri, T. racupalpa, and T. raptor) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. danielleae can be differentiated from all other Raptor Group by having Dgl-4 closer to the edge of the dorsum (dorsum width/distance between Dgl-4 ♀ = 1.57–1.70 in T. danielleae, 1.80–3.29 in others; ♂ = 1.42–1.52 in T. danielleae, 1.58–2.73 in others), except T. daemon (♀ = 1.59–1.67 ♂ = 1.45–1.65). T. danielleae can be differentiated from T. daemon by having a more elongate rostrum (length/width = 3.43–3.75 in T. danielleae, 2.91–3.31 in T. daemon) and dorsal pattern.

Diagnosis

Torrenticola delicatexa are similar to other members of Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. feminellai, T. indistincta, T. malarkeyorum, T. microbiscutella, T. pendula, T. sellersorum, T. tysoni, T. ululata, andT. whitneyae) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. indistincta and T. ululata), and being distributed in the east. T. delicatexa can be differentiated from T. ululata, T. indistincta, and T. feminellai by dorsal coloration and pattern. T. delicatexa can be differentiated from T. tysoni by having a stockier rostrum (length/width = 2.33–3.00 in T. delicatexa, 3.06–3.50 in A34). T. delicatexa can be differentiated from T. pendula by having a stockier gnathosomal bay (length/width = 1.28–2.22 in T. delicatexa, 2.42–2.90 in T. pendula), and a longer dorsum (♀ = 560–620 in T. delicatexa, 630–650 in T. pendula; ♂ = 420–465 in T. delicatexa, 500 in T. pendula). T. delicatexa can be differentiated from T. microbiscutella by having a less elongate dorsum (length/width = 1.38–1.56 in T. delicatexa, 1.63–1.75 in T. microbiscutella). Female T. delicatexa can be differentiated from female T. malarkeyorum, T. biscutella, and T. caerulea by having a longer genital field (175–185 in T. delicatexa, 153–170 in others). Male T. delicatexa can be differentiated from male T. biscutella by having a more ovoid dorsum (length/width = 1.44–1.56 in T. delicatexa; 1.37–1.42 in T. biscutella). Female T. delicatexa can be differentiated from female T. sellersorum by having a slightly more ovoid dorsum (length/width = 1.38–1.44 in T. delicatexa, 1.23–1.37 in T. sellersorum). Male T. delicatexa do not have any measurement differences with male T. malarkeyorum, T. caerulea, and T. sellersorum; however, they can be differentiated by dorsal coloration. T. delicatexa can be differentiated from T. whitneyae by having a slightly more ovoid dorsum (length/width ♀ = 1.38–1.44 in T. delicatexa, 1.26–1.38 in T. whitneyae; ♂ = 1.44–1.56 in T. delicatexa, 1.35–1.37 in T. whitneyae) and by dorsal coloration. Additionally, male T. delicatexa can be differentiated from male T. whitneyae by having more elongate pedipalpal tibiae (length/width = 2.89–3.63 in T. delicatexa, 2.48–2.70 in T. whitneyae).

Etymology

Habeeb (1955) did not offer an explanation for the specific epithet (delicatexa) and we are unable to offer helpful speculation.

Remarks

In all analyses, Torrenticola delicatexa groups with members of the Rusetria Complex with high support and specimens of this species were less than 2% different in COI sequence from each other. However, one specimen from Tennessee (DNA#1839) was 5% different; this specimen was collected from the same river as the other specimens and was indistinguishable morphologically. We refrain from speculating on this COI variation, but consider this specimen as an outlier, and thus within our hypothesis for T. delicatexa. The position of this species was only strongly supported in our combined analysis, where it is recovered as sister to two other species: T. ululata and T. glomerabilis. However, T. delicatexa does not resemble these species morphologically, and instead is quite similar to three more distantly-related species (T. biscutella, T. malarkeyorum, and T. caerulea).

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola dentirostra are similar to other members of the Nigroalba Group (T. flangipalpa, T. nigroalba, and T. solisorta) in being small, slightly elongate, and having purple dorsal coloration restricted posteriorly. T. dentirostra can be differentiated from most Torrenticola (except T. erectirostra, T. karambita, and T. robisoni) by having a dentate bump midway on the dorsal edge of the rostrum. T. dentirostra can be differentiated from T. karambita, T. erectirostra, and T. robisoni by having a straight rostrum (others have upturned rostra) and by dorsal pattern.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola dentirostra and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, small size, elongate subcapitular rostra, elongate pedipalpal tibiae, and dorsal purple coloration restricted to posterior half, place this species in the Raptor Complex and the Nigroalba Identification Group.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (5 ♀; 2 ♂) deposited in the CNC; other paratypes (3 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola dimorpha are similar to other members of the Tricolor Complex (T. bittikoferae, T. cardia, T. hoosieri, T. kringi, T. larvata, T. mohawk, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, and T. unimaculata) in having a short, conical rostrum. T. dimorpha can be differentiated from all other Torrenticola by having a dorsal plate with a medial extension covering nearly half the length of the anterio-medial platelets and by males having large, highly modified pedipalps, which are expanded vertically and laterally. Additionally, T. dimorpha can be differentiated from most other Tricolor Complex (except T. bittikoferae, T. hoosieri, and T. pearsoni) by being colorless, whereas most other members have bold patterning.

Etymology

Specific epithet (dimorpha) refers to the sexual dimorphism in terms of size and morphology (di, G. two; morphḗ, G. form), the resulting morphology is so unlike all other Torrenticolidae that upon first glance specimens appear to be a different family altogether.

Distribution

Texas (probably also extending southward into Mexico) (Figure 56).

Remarks

Torrenticola dimorpha groups with other members of the Tricolor Complex with high support and specimens of this species were less than 1% different in COI sequence from each other. In the combined analysis, T. dimorpha groups with T. larvata and these species are greater than 16% different in COI sequence from each other. This clade (T. dimorpha + T. larvata) is sister to all other eastern members of the Tricolor Complex.

This species is so unique that upon initial observation, specimens appear to be members of a different genus, especially the males. However, the short conical rostrum that is downturned in males is characteristic of other members of the Tricolor Identification Group.

This species hypothesis is supported by biogeography, high divergence between species, and by highly distinctive morphological characteristics outlined in the diagnosis. The high degree of sexual size dimorphism (males are 15–30% smaller than females) is only matched by most members of the Rusetria Complex, where males are usually 20–30% smaller than females.

Diagnosis

Torrenticola dolichodactyla are similar to other members of the Rala Group (T. rala, T. lamellipalpis, T. boettgeri, T. kurtvietsi, T. keesdavidsi, and T. anoplopalpa) by being colorless, having incomplete hind coxal margins and being distributed in the southwest. T. dolichodactyla can be differentiated from all other Rala Group by having longer pedipalpal tarsi (♂ = 52.5 in T. dolichodactyla, 10–20 in others) and Dgl-4 closer to the muscle scars (dorsum width/distance between Dgl-4 ♂ = 1.74 in T. dolichodactyla, 1.16–1.48 in others).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola dolichodactyla and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, incomplete hind coxal margins, distribution, and lack of color are consistent with placing this species in the Rala Identification Group.

Holotype (♀), allotype (♂), and most paratypes (4 ♀; 2 ♂) deposited in the CNC; other paratypes (5 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola dunni are similar to other members of the Rusetria “4-Plates” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. T. dunni can be differentiated from T. pollani by having a larger dorsum (length ♀ = 605–680 in T. dunni, 535–560 in T. pollani; ♂ = 500–540 in T. dunni, 440–492 in T. pollani; width ♀ = 440–490 in T. dunni, 410–420 in T. pollani; ♂ = 350–370 in T. dunni, 310–340 in T. pollani) ; and a stockier rostrum (length/width = 2.80–3.14 in T. dunni, 3.27–3.82 in T. pollani). Female T. dunni can be differentiated from female T. shubini by having a thinner rostrum (length/width = 2.8–3.0 in T. dunni, 2.5–2.7 in T. shubini). Male T. dunni can be differentiated from male T. shubini by having a longer anterior venter (277–285 in T. dunni, 215–238 in T. shubini). T. dunni can be differentiated from T. glomerabilis by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.2–1.4 in T. dunni, 1.5–1.7 in T. glomerabilis) and stockier tibiae (length/width ♀ = 3.27–3.50 in T. dunni, 4.11–4.50 in T. glomerabilis, ♂ = 3.25–3.44 in T. dunni, 3.55–4.38 in T. glomerabilis). Female T. dunni can be differentiated from female T. kittatinniana by having a longer pedipalp genu (70–75 in T. dunni, 64 in T. kittatinniana); a longer subcapitulum (ventral length = 330–355 in T. dunni, 310 in T. kittatinniana); and anterio-medial platelets more elongate (length/width = 2.33–2.54 in T. dunni, 2.83 in T. kittatinniana). Male T. dunni can be differentiated from male T. kittatinniana by having a longer anterior venter (277–285 in T. dunni, 235 in T. kittatinniana) and wider dorsum (350–370 in T. dunni, 340 in T. kittatinniana). T. dunni can be differentiated from T. rufoalba by having a larger dorsum (length ♀ = 605–680 in T. dunni, 550 in T. rufoalba; ♂ = 500–540 in T. dunni, 440 in T. rufoalba; width ♀ = 440–490 in T. dunni, 400 in T. rufoalba; ♂ = 350–370 in T. dunni; 320 in T. rufoalba). T. dunni can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle, and by having a longer anterior venter (♀ = 160–190 in T. dunni, 140–152.5 in T. skvarlai; ♂ = 277.5–285 in T. dunni, 177.5–205 in T. skvarlai).

Etymology

Specific epithet (dunni) named in honor of Rob Dunn of North Carolina State University, for his exceptional writings and research that personalize ecology by bringing nature indoors; and particularly for his storytelling ability, in which he wonderfully conveys that we humans, rather than being separate from nature, are indeed just as wild as what we perceive outdoors—a sentiment exemplified by his book, Wild Life of Our Bodies: Predators, Parasites, and Partners That Shape Who We Are Today (2011).

Remarks

In all analyses, Torrenticola dunni groups with two other members of the Rusetria Complex with high support and specimens are less than 1% different in COI sequence from each other. In all analyses, T. dunni groups with two other species: T. pollani and T. shubini. These species are greater than 5% different from each other in COI sequence and the ranges of T. T. dunni overlaps with T. shubini, but the ranges of these species do not overlap with T. pollani. Given our collection efforts across the Appalachians, it is reasonable to speculate that T. dunni is restricted to the southern Appalachians.

Based upon overall similarity, dorso-lateral platelet fusion, and distribution, we were able to place this species within the Eastern 2-Plate Identification Group

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola ellipsoidalis are similar to other members of the Ellipsoidalis Group (T. multiforma, T. occidentalis, and T. leviathan), in being among the largest Torrenticola in the west (dorsum length ♀ = 700–885; ♂ = 665–850), although T. sierrensis are also large (dorsum length ♀ = 700–880; ♂ = 590–735) but can easily be distinguished from the Ellipsoidalis Group by being circular instead of ellipsoid or rectangular (dorsum length/width = 1.17–1.28 in T. sierrensis, 1.30–1.67 in Ellipsoidalis Group). T. ellipsoidalis can be differentiated from T. multiforma by having stockier subcapitular rostra (length/width = 1.8–2.1 in T. ellipsoidalis, 2.5–2.8 in T. multiforma). T. ellipsoidalis can be differentiated from T. occidentalis (only known from females) by having a longer medial suture (40–57.5 in T. ellipsoidalis, 20 in T. occidentalis) and by having stockier anterio-lateral platelets (length/width = 2.00–2.39 in T. ellipsoidalis, 2.54 in T. occidentalis). T. ellipsoidalis can be differentiated from T. leviathan by having less elongate pedipalpal tibiae (length/width = 2.6–3.3 in T. ellipsoidalis, 3.4–4.2 in T. leviathan) and stockier anterio-medial platelets (length/width ♀ = 1.43–1.72 in T. ellipsoidalis, 1.94–2.14 in T. leviathan; ♂ = 1.53–2.00 in T. ellipsoidalis, 2.15 in T. leviathan).

Etymology

Marshall (1943) presumably named the specific epithet (ellipsoidalis) after the elongate body of this species, as she wrote, “the body is an ellipse.”

Distribution

Western (Figure 64). T. ellipsoidalis was previously recorded from Martis Creek and Gibbon River, Wyoming (Marshall 1943); and from Torch River, Saskatchewan (Quaglia & Conroy 1984). We expand the range into most of western North America. However, T. ellipsoidalis is not known from the southwest.

Remarks

Torrenticola ellipsoidalis groups other members of the Miniforma Complex with high support and most specimens are 0–3% different in COI sequence. This is higher sequence variability than in many species hypotheses presented herein. However, given the topology in the COI tree (Figure 10, 16) and morphological similarity, it seems apparent that the variability represents a continuum across a large distribution, rather than isolated species. An exception is that a single specimen (DNA#1930) is 2.9–3.6% different from the rest. This specimen is indistinguishable from other specimens and is collected from the same location. We do not find evidence to propose it as a separate species and therefore include it within T. ellipsoidalis.

In all analyses, T. ellipsoidalis groups with T. multiforma and T. regalis, which are greater than 10% different from each other. Based upon overall similarity, body size, and distribution, we place this species within the Ellipsoidalis Identification Group.

Upon examining the types of T. ellipsoidalis and T. rectiforma, all characters for both species overlap with members of only one clade in our analyses. Furthermore, the main character Habeeb (1974) used to differentiate T. rectiforma from T. ellipsoidalis was body size, which is known to be a highly variable character. Therefore, we synonymize T. rectiforma as the junior synonym of T. ellipsoidalis.

Type deposition

Holotype (♀), allotype (♂) deposited in the CNC; other paratypes (1 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola elongata are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini), Neoanomala Group (T. interiorensis and T. neoanomala), and T. bondi, T. erectirostra, T. robisoni, T. gorti, T. reduncarostra, T. irapalpa, T. racupalpa, T. skvarlai, and T. arktonyx. T. elongata can be differentiated from all other Torrenticola with similar dorsal patterning by having a more elongate dorsum (length/width ♀ = 1.92–2.08 in T. elongata, 1.17–1.58 in others; ♂ = 1.70–1.70 in T. elongata, 1.20–1.68 in others). Additionally, they can be differentiated from Rusetria 4-Plates and T. skvarlai by having distinct hind coxal margins, they can be differentiated from T. erectirostra and T. robisoni by having a straight, anteriorly-directed rostrum (upturned in others), and they can be differentiated from T. arktonyx by having an unmodified dorsal plate (T. arktonyx has distinctive longitudinal dark markings on the anterior portion of the dorsal plate that fade posteriorly).

Etymology

Specific epithet (elongata) refers to elongated bodies of this species, which is more pronounced than in all other North American Torrenticola (elongatus, L. prolonged).

Distribution

Known only from Tishomingo County, Mississippi (Figure 67).

Remarks

Torrenticola elongata groups with other members of the Raptor Complex with high support and specimens are less than 1% different in COI sequence from each other. In all analyses, T. elongata groups with two other species (T. gorti and T. bondi) which are 4% different from each other and have non-overlapping ranges.

Based upon overall similarity, an elongate body, and distribution, we place this species in the Elongata Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Torrenticola elusiva Fisher & Dowling, sp. n.

Material examined

HOLOTYPE (♀): from Canada, New Brunswick, Charlotte County, Rollingham, Whittier Ridge, Highway 770, 6.6 km east of covered bridge, 3 Oct 2011, by IM Smith, IMS110120, DNA 1857.

Type deposition

Holotype (♀) deposited in the CNC.

Diagnosis

Torrenticola elusiva are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. longitibia, T. mjolniri, T. racupalpa, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. elusiva can be differentiated from T. racupalpa by having a stockier subcapitulum (ventral length/height = 2.39 in T. elusiva, 2.48–2.73 in T. racupalpa); and by dorsal pattern. T. elusiva can be differentiated from T. irapalpa and T. daemon by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.5 in T. elusiva, 1.59–2.09 in others); a more elongate rostrum (length/width = 3.65 in T. elusiva, 2.66–3.39 in others); and by dorsal coloration and pattern. T. elusiva can be differentiated from T. gnoma by being larger (dorsum length = 645 in T. elusiva, 540–595 in T. gnoma); having a more elongate rostrum (length/width = 3.65 in T. elusiva, 2.74–3.13 in T. gnoma); and dorsal coloration. T. elusiva can be differentiated from T. mjolniri and T. ivyae by having stockier pedipalp tibiae (length/width = 4.42 in T. elusiva, 5.00–6.00 in others); and a stockier rostrum (length/width = 3.65 in T. elusiva, 3.81–4.32 in others). T. elusiva can be differentiated from T. raptor by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.50 in T. elusiva, 1.8–2.02 in T. raptor); shorter anterior venter (163.75 in T. elusiva, 205–240 in T. raptor); and stockier pedipalp tibiae (length/width = 4.42 in T. elusiva, 6–7.54 in T. raptor). T. elusiva can be differentiated from T. danielleae by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.5 in T. elusiva, 1.57–1.70 in T. danielleae) and by dorsal coloration. T. elusiva cannot be confidently differentiated from T. longitibia because T. elusiva is only known from a single female and T. longitibia is only known from two males; however, T. elusiva is only known from Charlotte County, New Brunswick, whereas T. longitibia is only known from Monroe County, Tennessee. Additionally, two character systems that vary minimally between sexes are rostrum and pedipalp tibiae proportions, which do differ between T. elusiva and T. longitibia as follows: pedipalp tibia stockier (4.42 in T. elusiva, 5.5–5.5 in T. longitibia) and rostrum stockier (3.65 in T. elusiva, 4.15–4.23 in T. longitibia).

Etymology

Specific epithet (elusiva) refers to the fact that we were only able to find a single specimen of this species, despite extensive searching among the abundant samples taken from the type locality in New Brunswick.

Distribution

Known only from Charlotte County, New Brunswick (Figure 70).

Remarks

Torrenticola elusiva groups with other members of the Raptor Complex in all analyses with high support. Only one specimen could be acquired for use in our analyses, so differences in COI sequence across specimens could not be investigated, but this single specimen was greater than 4% different in COI sequence from sister species. Furthermore, this species is known from only a single female, so morphological variation could not be investigated. However, this specimen was different enough in terms of morphology and sequence to warrant a separate description. We place this species within the Raptor Identification group based upon similarity with those species.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (6 ♀; 4 ♂) deposited in the CNC; other paratypes (3 ♀; 4 ♂) deposited in the ACUA.

Diagnosis

Torrenticola erectirostra are similar to other members of the Erectirostra Group (T. karambita and T. robisoni), species with similar dorsal patterning, such as Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini), Elongata Group (T. gorti and T. elongata), Neoanomala Group (T. interiorensis and T. neoanomala), T. bondi, T. irapalpa, T. racupalpa, and T. skvarlai. They can be differentiated from all other Torrenticola, except T. karambita and T. robisoni, by having a dentate, upturned rostrum that is wide when viewed ventrally. T. erectirostra can be differentiated from T. karambita by having dorsal coloration (T. karambita is colorless) and a slightly more elongate rostrum (length/width ♀ = 1.72–1.91 in T. erectirostra, 1.57–1.62 in T. karambita; ♂ = 2.0–2.2 in T. erectirostra, 1.6–1.95 in T. karambita). T. erectirostra can be differentiated from T. robisoni by having less elongate anterio-lateral platelets (length/width ♀ = 2.52–2.69 in T. erectirostra, 2.96–3.00 in T. robisoni) and by being distributed in the Appalachians, while T. robisoni is in the Interior Highlands.

Remarks

Torrenticola erectirostra groups with other members of the Raptor Complex with high support and specimens are 2.7% different from each other in COI sequence. This variation in COI is higher than in most species hypotheses proposed herein, especially since those specimens were form the same region (New Brunswick). However, we could not find morphological differences that corresponded to clades in our analysis, and we were only able to examine four sequence, therefore, we consider these specimens to represent a single species hypothesis.

This species groups with T. karambita and T. robisoni to form the Erectirostra Identification Group, which can be readily identified by the shape of the rostrum.

This species hypothesis is supported by biogeography, molecular divergence (although COI variation is greater than most hypotheses herein), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 3 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola feminellai are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. sellersorum, T. tysoni, T. ululata, T. whitneyae, and T. microbiscutella) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. T. feminellai can be differentiated from all other Eastern 2-Plates by having a more elongate rostrum (length/width ♀ = 3.05–3.38 in T. feminellai, 2.33–3.00 in others; ♂ = 3.14–3.38 in T. feminellai, 2.50–3.05 in others), except T. tysoni (3.06–3.50). Additionally, T. feminellai can be differentiated from all other Eastern 2-Plates by having a distinct dorsal pattern.

Etymology

Specific epithet (feminellai) named in honor of Jack Feminella, professor of biology at Auburn University, who believed in me (JRF) enough to employ me as a lab technician in stream ecology, write a winning recommendation letter for graduate school, and was the first to teach me how to conduct self-directed research.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola feminellai and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution in the east, and fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and the Eastern 2-Plate Identification Group.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (3 ♀; 4 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola flangipalpa are similar to other members of the Nigroalba Group (T. nigroalba, T. solisorta, and T. dentirostra) in being small, slightly elongate, having purple dorsal coloration restricted posteriorly, and having distinct yet poorly-defined hind coxal margins (can be indistinct, at least in males). T. flangipalpa are best differentiated from other members of the Nigroalba Group by having a flange-like, anteriorly-directed pedipalp femoral extension (this extension is tuberculate in other members of the Nigroalba Group). Additionally, T. flangipalpa can be differentiated from T. nigroalba and T. solisorta by having a longer anterior venter (235–265 in T. flangipalpa; 192–225 in others) and stockier pedipalpal tibiae (length/width ♀ = 4.79–5.0 in T. flangipalpa, 5.38–5.83 in others; length/width ♂ = 4.4–4.86 in T. flangipalpa, 5.08–5.33 in others). T. flangipalpa can be differentiated from T. dentirostra by having a smooth rostrum (T. dentirostra has a dentate bump midway on the dorsal edge of the rostrum).

Etymology

Specific epithet (flangipalpa) refers the expanded (i.e., flanged) pedipalp femoral tubercle (flange, English; palpus, L. hand, feeler), which distinguishes this species from other members of the Nigroalba Group.

Distribution

Remarks

Torrenticola flangipalpa groups with other members of the Raptor Complex with high support in all analyses and specimens are less than 1% different in COI sequence from each other. In all analyses, T. flangipalpa groups with two other morphologically similar species: T. nigroalba and T. solisorta. These three species are greater than 12% different from each other in COI sequence.

That clade of three species corresponds to an identification group, Nigroalba Group, the members of which are easily differentiated by their size, coloration, long medial suture in females, and overall appearance.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola folkertsae are similar to other members of the Partial 2-Plate Group (T. magnexa, T. priapus, and T. pulchra) in having anterio-lateral platelets partially fused to the dorsal plate and being distributed in the east. T. folkertsae can be differentiated from T. magnexa and T. pulchra by having more elongate pedipalpal tibiae (length/width = 4.05–4.83 in T. folkertsae, 2.61–4.00 in others) and by dorsal coloration and pattern. T. folkertsae can be differentiated from T. priapus by having more elongate pedipalpal tibiae (length/width ♀ = 4.5–4.83 in T. folkertsae, 3.9–4.22 in T. priapus ♂ = 4.05–4.33 in T. folkertsae, 3.5–3.78 in T. priapus) and a less elongate rostrum (length/width = 2.55–3.00 in T. folkertsae, 3.17–3.39 in T. priapus).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola folkertsae and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution, and partial fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and the Partial 2-Plate Identification Group.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (18 ♀; 19 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in the ACUA.

Diagnosis

Torrenticola glomerabilis are similar to other members of the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. T. glomerabilis can be differentiated from T. dunni, T. shubini, T. kittatinniana, by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.53–1.66 in T. glomerabilis, 1.20–1.42 in others) and stockier tibiae (length/width ♀ = 4.11–4.50 in T. glomerabilis, 3.27–3.60 in others; ♂ = 3.55–4.38 in T. glomerabilis, 2.80–3.45 in others). T. glomerabilis can be differentiated from T. pollani and T. rufoalba by having stockier anterio-medial platelets (length/width ♀ = 1.9–2.3 in T. glomerabilis, 2.5–3.0 in others; ♂ = 1.9–2.2 in T. glomerabilis, 2.3–2.9 in others) and wider dorsum (♀ = 460–490 in T. glomerabilis, 400–420 in others; ♂ = 395–430 in T. glomerabilis, 310–340 in others). T. glomerabilis can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle, and by having a longer anterior venter (♀ = 202–213 in T. glomerabilis, 140–153 in T. skvarlai; ♂ = 240–280 in T. glomerabilis, 177–205 in T. skvarlai).

Remarks

Torrenticola glomerabilis groups with other members of the Rusetria Complex with high support and specimens are less than 1% different in COI sequence from each other. In all analyses, T. glomerabilis groups with two other species, T. delicatexa and T. ululata, which are 10–13% different from each other. Of these species, T. glomerabilis is the only one with the lateral platelets free from the dorsal plate. Because of this, we place T. glomerabilis within the Eastern 4-Plate Identification Group, which can be differentiated by having rounder bodies than any other species in the Rusetria Complex.

Torrenticola glomerabilis occupy an interesting position phylogenetically by being nested between the Eastern 2-Plate and Eastern 4-Plate Identification Groups (Figure 6, 12). Their unique shape and interesting phylogenetic affinity flag this species as important to future studies on the evolution of eastern members of the Rusetria Complex.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola gnoma are similar to other members of the Raptor Group (T. irapalpa, T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. gnoma can be differentiated from T. elusiva by being smaller (dorsum length = 540–595 in T. gnoma, 645 in T. elusiva); having a stockier rostrum (length/width = 2.74–3.13 in T. gnoma, 3.65 in T. elusiva); and by dorsal coloration. T. gnoma can be differentiated from T. racupalpa by having a stockier rostrum (length/width = 2.74–3.13 in T. gnoma, 3.56–3.88 in T. racupalpa) and by dorsal coloration and pattern. T. gnoma can be differentiated from T. irapalpa, T. danielleae, and T. daemon by dorsal coloration and pattern. Additionally, female T. gnoma can be differentiated from female T. irapalpa, T. danielleae, and T. daemon by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 ♀ = 2.65–3.29 in T. gnoma, 1.57–2.09 in others). T. gnoma can be differentiated from T. mjolniri, T. longitibia, T. raptor, and T. ivyae by having stockier pedipalp tibiae (length/width = 3.88–4.67 in T. gnoma, 4.75–7.54 in others) and a stockier rostrum (length/width = 2.56–3.23 in T. gnoma, 3.44–4.4 in others).

Remarks

Torrenticola gnoma groups with other members of the Raptor Complex with high support and specimens of this species were less than 1% different in COI sequence from each other. In the combined analysis, T. gnoma groups with T. irapalpa with high support, but the position of this clade was not recovered. These species are greater than 9% from each other. Based upon overall similarity, distribution, and phylogenetic position, this species is placed within the Raptor Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola gorti specimens from Tellico River system in Monroe County (Tennessee) can be differentiated from all other Torrenticola by the distinctively dark coloration with a red spot dorsally. Other color morphs are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini), Neoanomala Group (T. interiorensis and T. neoanomala), and T. bondi, T. elongata, T. reduncarostra, T. erectirostra, T. robisoni, T. irapalpa, T. racupalpa, T. skvarlai, and T. arktonyx. They can be differentiated from Rusetria 4-Plates and T. skvarlai by having distinct hind coxal margins. T. gorti can be differentiated from T. erectirostra, T. robisoni, and T. reduncarostra by having a straight, anteriorly-directed rostrum (upturned in others). T. gorti can be differentiated from T. arktonyx by having an unmodified dorsal plate (T. arktonyx has distinctive longitudinal dark markings on the anterior portion of the dorsal plate that fade posteriorly). T. gorti can be differentiated from T. racupalpa and T. irapalpa by being more elongate (dorsum length/width = 1.47–1.6 in T. gorti, 1.15–1.3 in others) and tibia/femur (0.65–0.73 in T. gorti, 0.77–0.91 in others). T. gorti can be differentiated from T. elongata by having a more ovoid dorsum (length/width = 1.47–1.58 in T. gorti, 1.7–2.1 in T. elongata) and larger dorsum (length ♀ = 570–600 in T. gorti, 540–565 in T. elongata; ♂ = 500–525 in T. gorti, 450–460 in T. elongata). T. gorti can be differentiated from the Neoanomala Group by having a more elongate dorsum (length/width ♀ = 1.47–1.58 in T. gorti, 1.29–1.43 in Neoanomala Group; ♂ = 1.54–1.58 in T. gorti, 1.34–1.50 in Neoanomala Group) and having a more elongate rostrum (length/width = 3.29–3.73 in T. gorti, 2.59–2.90 in Neoanomala Group). T. gorti can be differentiated from T. bondi by having a more elongate dorsum (length/width = 1.47–1.58 in T. gorti, 1.32–1.45 in T. bondi) and having a more elongate rostrum (length/width = 3.32–3.73 in T. gorti, 2.76–3.13 in T. bondi).

Etymology

Specific epithet (gorti) refers to Gort, the fictional giant robot of The Day the Earth Stood Still. In the 2008 film, Gort was depicted with a dark body and a single red eye that shot a destructive beam. This species is named for the resemblance that the distinctive specimens from Tennessee have to Gort’s red eye.

Distribution

Remarks

Torrenticola gorti groups with other members of the Raptor Complex with high support and specimens of this species were less than 1% different in COI sequence from each other. In all analyses, T. elongata groups with two other species (T. elongata and T. bondi) which are 4% different from each other and have non-overlapping ranges.

T. elongata to form the Elongata Group in all analyses with high support.

Based upon overall similarity, an elongate body, and distribution, we place this species in the Elongata Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Members of this species can be highly variable in color. Some members have reddish-purple or purple dorsal coloration that is separated into anterior and posterior portions. Ventral coloration can be bold, faint, or absent. Members from Tellico River, Monroe County (Tennessee), can be readily differentiated from all other Torrenticola by being dark navy blue with a red dorsal oval.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (3 ♂) deposited in the CNC; other paratypes (1 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola hoosieri are similar to other members of the Tricolor Complex (T. bittikoferae, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, and T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. hoosieri can be differentiated from all other Tricolor Complex, and nearly all other Torrenticola, by lacking pedipalp ventral extensions on femora and genua. Additionally, T. hoosieri can be differentiated from all other Tricolor Complex by having more elongate pedipalp tibiae (3.67–4.33 in T. hoosieri, 2.65–3.55 in others) and by being colorless (rarely with diffuse pink dorsal coloration), except T. bittikoferae, T. pearsoni, and T. dimorpha.

Diagnosis

Torrenticola indistincta are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. malarkeyorum, T. pendula, T. sellersorum, T. tysoni, T. ululata, T. whitneyae, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, and being distributed in the east. T. indistincta can be differentiated from other Eastern 2-Plates by having faint coloration separated into anterior and posterior portions connected medially. Female T. indistincta can be differentiated from female T. caerulea by having a larger genital field (length = 185–225 in T. indistincta, 155–165 in T. caerulea; width = 185–205 in T. indistincta, 120–145 in T. caerulea). Male T. indistincta can be differentiated from male T. caerulea by having a larger dorsum (length = 480–645 in T. indistincta, 405–460 in T. caerulea; width = 315–470 in T. indistincta, 260–305 in T. caerulea). T. indistincta can be differentiated from T. microbiscutella by having a less elongate dorsum (length/width = 1.21–1.52 in T. indistincta; 1.63–1.75 in T. microbiscutella).

Etymology

Marshall (1929) named the specific epithet (indistincta) in reference to the Rusetria Complex character of fused (“indistinct”) lateral platelets.

Distribution

Midwest and into Manitoba (Figure 96). Young (1969) reported this species from Colorado, but this likely represents T. mulleni rather than T. indistincta.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola indistincta and therefore this species was not included in our phylogenetic analyses. However, we were able to examine type material and additional material preserved in GAW. The fusion of the lateral platelets to the dorsal plate clearly places this species among the Rusetria Complex and its distribution is consistent with placement within the Eastern 2-Plate Identification Group.

Although Young (1969) reported this species in Colorado, we suspect that record represents the superficially similar T. mulleni based upon distribution.

Diagnosis

Torrenticola interiorensis are similar to species with similar dorsal patterning, such as the Rusetria 4-Plate Group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini), Elongata Group (T. gorti, T. elongata, and T. reduncarostra), and T. bondi, T. erectirostra, T. robisoni, T. irapalpa, T. neoanomala, T. racupalpa, T. skvarlai, and T. arktonyx. They can be differentiated from Rusetria 4-Plates and T. skvarlai by having distinct hind coxal margins. T. interiorensis can be differentiated from T. erectirostra, T. robisoni and T. reduncarostra by having a straight, anteriorly-directed rostrum (upturned in T. erectirostra and T. reduncarostra). T. interiorensis can be differentiated from T. arktonyx by having an unmodified dorsal plate (T. arktonyx has distinctive longitudinal dark markings on the anterior portion of the dorsal plate). T. interiorensis can be differentiated from T. racupalpa by having less elongate pedipalpal tibiae (length/width = 3.76–4.22 in T. interiorensis; 4.44–5.50 in T. racupalpa) and less elongate rostrum (length/width = 2.63–2.88 in T. interiorensis; 3.56–3.88 in T. racupalpa). T. interiorensis can be differentiated from T. irapalpa by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 ♀ = 1.48–1.61 in T. interiorensis, 1.81–2.09 in T. irapalpa; ♂ = 1.42–1.45 in T. interiorensis, 1.58–1.86 in T. irapalpa) and more ovoid dorsum (length/width ♀ = 1.29–1.38 in T. interiorensis, 1.20–1.28 in T. irapalpa; ♂ = 1.34–1.47 in T. interiorensis, 1.26–1.30 in T. irapalpa). T. interiorensis can be differentiated from Elongata Group by being slightly more ovoid (dorsum length/width ♀ = 1.29–1.38 in T. interiorensis, 1.45–2.08 in Elongata Group; ♂ = 1.34–1.47 in T. interiorensis, 1.51–1.7 in Elongata Group) and having a stockier rostrum (length/width = 2.63–2.88 in T. interiorensis, 3.24–4.00 in Elongata Group). T. interiorensis can be differentiated from T. bondi by having a longer medial suture (♀ = 25–30 in T. interiorensis, 10–15 in T. bondi; ♂ = 75–83 in T. interiorensis, 55–70 in T. bondi), anterior venter/genital field width (♀ = 1.31–1.38 in T. interiorensis, 1.15–1.25 in T. bondi; ♂ = 2.09–2.27 in T. interiorensis, 1.95–2.05 in T. bondi), and Dgl-4 closer to edge of dorsum (dorsum width/distance between Dgl-4 ♀ = 1.48–1.61 in T. interiorensis, 1.63–1.72 in T. bondi; ♂ = 1.42–1.45 in T. interiorensis, 1.48–1.62 in T. bondi). Female T. interiorensis can be differentiated from female T. neoanomala by having stockier anterio-lateral platelets (length/width = 2.62–2.67 in T. interiorensis, 2.86–3.09 in T. neoanomala). Male T. interiorensis can be differentiated from male T. neoanomala by having a shorter anterior venter (220–240 in T. interiorensis, 267.5–290 in T. neoanomala) and a shorter genital field (132–138 in T. interiorensis, 145–160 in T. neoanomala).

Etymology

Specific epithet (interiorensis) refers to the Interior Highlands, where this species was found within both major regions (Ozarks and Ouachitas), but not found outside these regions, which suggests it is endemic to the region.

Distribution

Interior Highlands (Ozarks and Ouachitas), likely endemic (Figure 99).

Remarks

Torrenticola interiorensis groups with other members of the Raptor Complex with high support and specimens are less than 2% different in COI sequence from each other. In the combined analysis, T. interiorensis groups with the superficially similar T. neoanomala, and specimens from these species are greater than 9% different in COI sequence from each other. Based upon this relationship and their similarity, we place these species in the Neoanomala Identification Group. The Neoanomala Group shares a phylogenetic affinity for members of the similar-looking Erectirostra Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (34 ♀; 20 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola irapalpa are similar to other members of the Raptor Group (T. gnoma, T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. irapalpa can be differentiated from T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, and T. ivyae by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.81–2.09 in T. irapalpa, 2.19–2.77 in others) and a less elongate rostrum (length/width = 2.66–3.39 in T. irapalpa; 3.56–4.32 in others). T. irapalpa can be differentiated from T. gnoma by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 ♀ = 1.81–2.09 in T. irapalpa, 2.65–3.29 in T. gnoma; ♂ = 1.58–1.86 in T. irapalpa, 2.06–2.73 in T. gnoma) and by dorsal coloration and pattern. T. irapalpa can be differentiated from T. raptor by having less elongate tibiae (length/width ♀ = 4.09–5.67 in T. irapalpa, 6.00–7.54 in T. raptor; ♂ = 4.25–4.75 in T. irapalpa, 5.29–5.63 in T. raptor); less elongate subcapitulum (ventral length/height = 2.52–2.90 in T. irapalpa, 2.98–3.27 in T. raptor); and by dorsal pattern. T. irapalpa can be differentiated from T. danielleae by having Dgl-4 further from the dorsal edge (dorsal width/distance between Dgl-4 = ♀ = 1.81–2.09 in T. irapalpa, 1.57–1.70 in T. danielleae; ♂ = 1.58–1.86 in T. irapalpa, 1.42–1.52 in T. danielleae); a less elongate rostrum (length/width = 2.66–3.39 in T. irapalpa, 3.43–3.75 in T. danielleae); and by dorsal coloration and pattern. Female T. irapalpa can be differentiated from female T. daemon by having Dgl-4 further from the dorsal edge (dorsal width/distance between Dgl-4 ♀ = 1.81–2.09 in T. irapalpa, 1.59–1.67 in T. daemon) and a less elongate gnathosomal bay (length/width ♀ = 1.35–1.86 in T. irapalpa, 1.95–2.42 in T. daemon). Male T. irapalpa can be differentiated from male T. daemon by dorsal coloration and pattern.

Etymology

Specific epithet (irapalpa) refers to the pedipalps of this species, which resemble ferocious weapons of wrath (ira, L. fury, rage, wrath; palpus, L. hand, feeler).

Distribution

Primarily eastern (Figure 102), but note that T. irapalpa is one of few Torrenticola found in the Great Plains, at least in the south (Texas) and north (Saskatchewan).

Remarks

Torrenticola irapalpa groups with other members of the Raptor Complex with high support and specimens of this species are less than 2% different in COI sequence from each other. In the combined analysis, T. irapalpa groups with T. gnoma with high support, but the position of this clade was not recovered. These species are greater than 9% from each other. Based upon overall similarity, distribution, and phylogenetic position, this species is placed within the Raptor Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (3 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola ivyae are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, T. raptor, T. danielleae, and T. daemon) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. ivyae can be differentiated from T. gnoma, T. elusiva, T. danielleae, and T. daemon by having a more elongate rostrum (length/width ♀ = 4.00–4.15 in T. ivyae, 2.74-3.75 in others; ♂ = 3.85–4.08 in T. ivyae, 2.56–3.57 in others) and more elongate pedipalpal tibiae (length/width ♀ = 5.07–5.64 in T. ivyae, 4.05–5.00 in others, ♂ = 4.75–5.20 in T. ivyae, 3.88–4.44 in others). T. ivyae can be differentiated from T. irapalpa, T. raptor, T. danielleae, and T. daemon by having Dgl-4 closer to the muscle scars (dorsum width/distance between Dgl-4 = 2.20–2.75 in T. ivyae, 1.42–2.09 in others). T. ivyae can be differentiated from T. longitibia (known only from males) by femur/genu (1.83–1.88 in T. ivyae, 2.1–2.17 in T. longitibia) and having less elongate tibiae (length/width = 4.75–5.20 in T. ivyae, 5.50–5.50 in T. longitibia). Female T. ivyae can be differentiated from female T. racupalpa by having a more elongate rostrum (length/width = 4.00–4.15 in T. ivyae, 3.56–3.82 in T. racupalpa) and more elongate pedipalpal tibiae (length/width = 5.07–5.64 in T. ivyae, 4.44–5.00 in T. racupalpa). Male T. ivyae can be differentiated from male T. racupalpa by having a longer anterior venter (♂ 220–230 in T. ivyae, 200–205 in T. racupalpa) and a shorter genital field (♂ 142–148 in T. ivyae, 160–165 in T. racupalpa). Female T. ivyae can be differentiated from female T. mjolniri by having a smaller dorsum (length ♀ = 550–590 in T. ivyae, 605–640 in T. mjolniri; width ♀ = 460–500 in T. ivyae, 510–545 in T. mjolniri) and a shorter anterior venter (♀ 155–170 in T. ivyae, 180–195 in T. mjolniri). Male T. ivyae can be differentiated from male T. mjolniri by having a less elongate subcapitulum (ventral length/width = 2.57–2.75 in T. ivyae, 2.82–3.00 in T. mjolniri). Additionally, T. ivyae can be differentiated from T. mjolniri by being found in Florida (T. ivyae is known from the northeast).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola ivyae and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, elongate subcapitular rostra, elongate pedipalpal tibiae, and Dgl-4 close to the muscle scars, are consistent with placing this species in the Raptor Complex and Raptor Identification Group.

Etymology

Specific epithet (karambita) refers to the upturned rostrum that has dentation on both sides in females, which resembles a karambit—small, recurved knives used in the Filipino martial arts practiced by JRF. The karambit is thought to have originated with the Minangkabau people of West Sumatra based upon a similarity to a tiger’s claws.

Distribution

Known only from Great Smokey Mountains National Park, Sevier County, Tennessee (Figure 108).

Remarks

Torrenticola karambita groups with other members of the Raptor Complex with high support in all analyses and specimens are less than 2% different in COI sequence from each other. In the combined analysis, T. karambita groups with two other species that share the modified subcapitulum with upturned rostrum: T. erectirostra and T. robisoni. These species are greater than 9% different from each other. Based upon overall similarity, distribution, and phylogenetic position, these species are placed within the Erectirostra Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%), high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola keesdavidsi are similar to other members of the Rala Group (T. rala, T. lamellipalpis, T. boettgeri, T. kurtvietsi, T. dolichodactyla, and T. anoplopalpa) by being colorless, having incomplete hind coxal margins and being distributed in the southwest. T. keesdavidsi can be differentiated from all other Rala Group by having a shorter dorsum (length ♀ = 555–605 in T. keesdavidsi, 630–800 in others; ♂ = 500–590 in T. keesdavidsi, 600–780 in others) and dentate, flanged ventral extensions on the femora (others are lacking extensions, have tuberculate extensions, or flat, wide lamellate extensions). Additionally, T. keesdavidsi can be differentiated from all other Rala Group by having more elongate pedipalpal tibiae (length/width = 4.50–5.20 in T. keesdavidsi, 1.75–3.38 in others), except T. lamellipalpis (4.32–4.94).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola keesdavidsi and therefore this species is not included in our phylogenetic analyses. We were also unable to examine type material. However, we were able to examine new material from Arizona and New Mexico that fits well within the species hypothesis proposed by Cramer (1992). The overall appearance, incomplete hind coxal margins, distribution, and lack of color place this species in the Rala Group.

Diagnosis

Torrenticola kittatinniana are similar to other members of the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. pollani, T. rufoalba and T. shubini) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. Female T. kittatinniana can be differentiated from female T. dunni by having shorter pedipalpal genua (64 in T. kittatinniana, 70–75 in T. dunni); a shorter subcapitulum (ventral length = 310 in T. kittatinniana, 330–355 in T. dunni); and stockier anterio-medial platelets (length/width = 2.83 in T. kittatinniana, 2.33–2.54 in T. dunni). Male T. kittatinniana can be differentiated from male T. dunni by having a shorter anterior venter (235 in T. kittatinniana, 277–285 in T. dunni) and thinner dorsum (340 in T. kittatinniana, 350–370 in T. dunni). T. kittatinniana can be differentiated from T. pollani by having a stockier rostrum (length/width = 2.71–3.16 in T. kittatinniana, 3.27–3.82 in T. pollani) and stockier tibiae (length/width ♀ = 3.3 in T. kittatinniana, 3.8–4.2 in T. pollani; ♂ = 2.80 in T. kittatinniana, 3.4–3.8 in T. pollani). Female T. kittatinniana can be differentiated from female T. shubini by having a more elongate rostrum (length/width = 3.16 in T. kittatinniana, 2.5–2.7 in T. shubini) and a shorter subcapitulum (125 in T. kittatinniana, 140–145 in T. shubini). Male T. kittatinniana can be differentiated from male T. shubini by having a longer dorsum (500 in T. kittatinniana, 400–465 in T. shubini) and a longer genital field (115 in T. kittatinniana, 90–108 in T. shubini). T. kittatinniana can be differentiated from T. glomerabilis by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.2–1.4 in T. kittatinniana, 1.5–1.7 in T. glomerabilis) and stockier tibiae (length/width ♀ = 3.3 in T. kittatinniana, 4.11–4.5 in T. glomerabilis; ♂ = 2.8 in T. kittatinniana, 3.5–4.4 in T. glomerabilis). T. kittatinniana can be differentiated from T. rufoalba by having a longer dorsum (♀ = 640 in T. kittatinniana, 550 in T. rufoalba; ♂ = 500 in T. kittatinniana, 440 in T. rufoalba) and more elongate anterio-medial platelets (length/width = 2.83–2.88 in T. kittatinniana, 2.45–2.61 in T. rufoalba). Additionally, male T. kittatinniana have a longer anterior venter (235 in T. kittatinniana, 195 in T. rufoalba). T. kittatinniana can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle, and by having a longer anterior venter (♀ = 165 in T. kittatinniana, 140–152.5 in T. skvarlai; ♂ = 235 in T. kittatinniana, 177.5–205 in T. skvarlai).

Etymology

Habeeb (1955) did not specify an explanation for the specific epithet (kittatinniana). However, we suspect it refers to the type locality, which is located in the Great Kittatinny Valley, which is named for Kittatinny Mountain in northwestern New Jersey, a northern extension of the Appalachian Ridge and Valley province.

Distribution

Northern New Jersey (Figure 114).

Remarks

Unfortunately, we were unable to acquire more specimens of Torrenticola kittatinniana and therefore this species is not included in our phylogenetic analyses. We were able to examine the type specimens. Based upon overall similarity, fusion of the posterio-lateral platelets with the dorsal plate, and distribution, this species clearly groups with other members of the Rusetria Complex and we are able to place it within the Eastern 4-Plate Identification Group.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola kringi are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. kringi can be differentiated from most Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern of a large anterior dorsal spot. The only other species with this pattern is T. ululata, which, like all Rusetria 2-Plates, have anterio-lateral platelets fused to the dorsal plate and T. unimaculata, which has a stockier rostrum (length/width = 2.6–3.2 in T. kringi, 1.9–2.2 in T. unimaculata). T. kringi are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, and T. mohawk). T. kringi can be further differentiated from all other members of the Tricolor Complex by having a more elongate rostrum (length/width = 2.67–3.13 in T. kringi, 1.29–2.59).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola kringi and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, conical rostrum that is downturned in males, and distribution, are consistent with placing this species in the Tricolor Complex and among eastern members of the Tricolor Identification Group.

Diagnosis

Torrenticola kurtvietsi are similar to other members of the Rala Group (T. rala, T. keesdavidsi, T. boettgeri, T. lamellipalpis, T. dolichodactyla, and T. anoplopalpa) by being colorless, having incomplete hind coxal margins and being distributed in the southwest. T. kurtvietsi can be differentiated from all other Rala Group by having a more elongate gnathosomal bay (length/width = 4.47–5.43 in T. kurtvietsi, 1.48–2.73 in others), except T. boettgeri (3.85–5.00); and stockier pedipalpal tibiae (length/width = 1.75–2.00 in T. kurtvietsi, 2.71–5.20 in others), except T. boettgeri (1.86–2.14). T. kurtvietsi can be differentiated from T. boettgeri by having a less elongate dorsum (length/width = 1.29–1.42 in T. kurtvietsi, 1.74–1.82 in T. boettgeri) and a more elongate subcapitulum (ventral length/width = 2.51–2.70 in T. kurtvietsi, 1.96–2.07 in T. boettgeri).

Diagnosis

Torrenticola larvata are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. larvata can be differentiated from all other Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern. T. larvata can be further differentiated from T. bittikoferae, T. sierrensis, T. tricolor, T. trimaculata, T. kringi, and T. mohawk by being more elongate (length/width = 1.41–1.57 in T. larvata; 1.17–1.39 in others); and from T. bittikoferae, T. olliei, T. sierrensis, T. trimaculata, T. unimaculata, T. dimorpha, and T. mohawk by having a more elongate rostrum (length/width = 2.32–2.53 in T. larvata, 1.56–2.27 in others).

Etymology

Cherri et al. (2016) named the specific epithet (larvata) for the anterior coloration that gives adults a masked appearance (larvat, L. masked).

Remarks

Torrenticola larvata groups with other members of the Tricolor Complex with high support in all analyses and specimens are less than 1% different in COI sequence from each other. In the combined analysis, T. larvata groups with T. dimorpha to form a clade sister to all other eastern members of this complex. These species are greater than 11% from each other. Based upon overall similarity, short conical rostrum, long pedipalp tibiae, phylogenetic position, and distribution, we were able to place this species in the Tricolor Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%), high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (1 ♀) deposited in the CNC; other paratypes (1 ♀) deposited in the ACUA.

Diagnosis

Torrenticola leviathan are similar to other members of the Ellipsoidalis Group (T. multiforma, T. occidentalis, and T. ellipsoidalis), in being among the largest Torrenticola in the west (dorsum length ♀ = 700–885; ♂ = 665–850), although T. sierrensis are also large (dorsum length ♀ = 700–880; ♂ = 590–735) but can easily be distinguished from the Ellipsoidalis Group by being circular instead of ellipsoid or rectangular (dorsum length/width = 1.17–1.28 in T. sierrensis, 1.30–1.67 in Ellipsoidalis Group). T. leviathan can be differentiated from all other Ellipsoidalis Group by having more elongate pedipalpal tibiae (length/width = 3.43–4.20 in T. leviathan, 2.64–3.33 in others).

Etymology

Specific epithet (leviathan) refers to the large body size of this species, surpassed by few other Torrenticola (liwyātān, Hebrew, a large aquatic animal; noun in apposition). The Leviathan (modern spelling) is depicted in Jewish mythology (as written in the Tanakh) as one of two huge beasts—the Leviathan in the ocean and the Behemoth on land.

Distribution

Northwestern California (Figure 129).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola leviathan and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, large size, and western distribution, places this species in the Miniforma Complex and the Ellipsoidalis Identification Group.

Diagnosis

Torrenticola longitibia are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. mjolniri, T. elusiva, T. racupalpa, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. longitibia can be differentiated from all other members of the Raptor Group (both males and females) by having a longer femur with respect to the genu (femur/genu = 2.1–2.17 in T. longitibia, 1.66–2.00 in others).

Remarks

Torrenticola longitibia is known only from two males, only one of which was available for molecular data and that specimen groups with other members of the Raptor Complex with high support. In all analyses, T. longitibia groups with T. mjolniri, and these species are more than 4% different in COI sequence from each other. The position of that clade varies with dataset. Based upon overall similarity, phylogenetic position, shape of the pedipalps, and distribution, we were able to place this species within the Raptor Identification Group.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola magnexa are similar to other members of the Partial 2-Plate Group (T. folkertsae, T. pulchra, and T. priapus) in having anterio-lateral platelets partially fused to the dorsal plate and being distributed in the east. T. magnexa can be differentiated from other Partial 2-Plate Group by dorsal coloration and pattern. T. magnexa can be further differentiated from T. New 23A by having a less elongate rostrum (length/width = 2.25–3.00 in T. magnexa, 3.17–3.39 in T. priapus). T. magnexa can be further differentiated from T. folkertsae by having less elongate pedipalpal tibiae (length/width = 3.21–4.00 in T. magnexa, 4.05–4.83 in T. folkertsae). Male T. magnexa can be further differentiated from male T. pulchra by having a larger genital field (length ♂ = 125–148 in T. magnexa, 110–123 in T. pulchra; width ♂ = 115–125 in T. magnexa, 87–95 in T. pulchra) and more elongate pedipalpal tibiae (length/width ♂ = 3.78–4.00 in T. magnexa, 3.00–3.35 in T. pulchra). Female T. magnexa can be differentiated from female T. pulchra by having a wider genital field (♀ 170–188 in T. magnexa, 147–160 in T. pulchra) and longer pedipalpal tibiae (♀ 102–113 in T. magnexa, 82–93 in T. pulchra).

Etymology

Habeeb (1957) did not specify an etymology for the specific epithet (magnexa). However, surely this name refers to the similarity of this species to the Palaearctic T. connexa (Koenike, 1908) (néos, G. new).

Distribution

Remarks

Upon examining the types of T. magnexa and T. neoconnexa Habeeb, 1957, all characters for both species overlap with members of only one clade in our analyses. Furthermore, the primary character Habeeb (1955, 1957, 1961) used to differentiate T. magnexa from T. neoconnexa was body size, which is known to be a highly variable character. Therefore, it is apparent that these represent the same species hypothesis and must be synonymized. We therefore synonymize T. neoconnexa as the junior synonym of T. magnexa.

In all analyses, Torrenticola magnexa groups with other members of the Rusetria Complex with high support, all specimens were less than 1% different in COI sequence from each other, and these specimens were 11–13% different from sister species. In the combined analysis, all eastern members of Rusetria Complex are monophyletic, and T. magnexa was recovered at the base of that eastern clade. Interestingly, most of the species within the more basal lineages of this eastern clade have lateral platelets that are free from the dorsal plate; whereas western species and most eastern species have lateral platelets fused to the dorsal plate. This is interesting because T. magnexa, which have lateral platelets partially fused to the dorsal plate, is recovered in an intermediate position between western species that have fused platelets and eastern species with unfused platelets.

Based upon the partially fused posterio-lateral platelets and the distribution, we place this species within the Partial 2-Plate Identification Group.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola malarkeyorum are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. pendula, T. sellersorum, T. tysoni, T. ululata, T. whitneyae, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. T. malarkeyorum can have variable coloration, including light bluish purple and reddish purple. Although several other species are purplish, some T. malarkeyorum are easily recognizable because they have bluish-purple coloration similar to T. tysoni and T. biscutella, albeit much fainter than these species. T. malarkeyorum can be differentiated from T. ululata, T. indistincta, and T. feminellai by dorsal coloration and pattern. T. malarkeyorum can be differentiated from T. tysoni by having a stockier rostrum (length/width = 2.57–2.89 in T. malarkeyorum, 3.06–3.5 in T. tysoni). Female T. malarkeyorum can be differentiated from female T. biscutella by having a longer subcapitulum (ventral length = 317.5–335 in T. malarkeyorum, 290–315 in T. biscutella). Male T. malarkeyorum can be differentiated from male T. biscutella by having a slightly more ovoid dorsum (length/width = 1.42–1.56 in T. malarkeyorum; 1.37–1.42 in T. biscutella. Additionally, although T. malarkeyorum and T. biscutella have the same dorsal coloration and pattern, often the coloration is faint in T. malarkeyorum and bold in T. biscutella. Female T. malarkeyorum can be differentiated from female T. caerulea by having a wider genital field (152.5–165 in T. malarkeyorum, 120–145 in T. caerulea). Additionally, T. malarkeyorum can be differentiated from T. caerulea by dorsal coloration and pattern. T. malarkeyorum can be differentiated from T. pendula by having a stockier gnathosomal bay (length/width = 1.62–2.26 in T. malarkeyorum, 2.42–2.90 in T. pendula); more elongate pedipalp tibiae (length/width = 3.22–3.60 in T. malarkeyorum, 2.78–3.05 in T. pendula); and by dorsal pattern. T. malarkeyorum can be differentiated from T. whitneyae by having more elongate pedipalpal tibiae (length/width = 3.22–3.60 in T. malarkeyorum, 2.42–2.95 in T. whitneyae) and by anterior venter/genital field length (♀ = 0.85–0.89 in T. malarkeyorum, 0.59–0.75 in T. whitneyae; ♂ = 1.52–1.88 in T. malarkeyorum, 1.37–1.43 in T. whitneyae). T. malarkeyorum can be differentiated from T. microbiscutella by having a less elongate dorsum (length/width = 1.33–1.56 in T. malarkeyorum, 1.63–1.75 in T. microbiscutella). Female T. malarkeyorum can be differentiated from female T. delicatexa by having a shorter genital field (162.5–170 in T. malarkeyorum, 175–198 in T. delicatexa). Female T. malarkeyorum can be differentiated from female T. sellersorum by anterior venter/genital field length (0.85–0.89 in T. malarkeyorum, 0.69–0.77 in T. sellersorum). Male T. malarkeyorum do not have any measurement differences with male T. delicatexa, and T. sellersorum; however, they can be differentiated by dorsal coloration.

Remarks

Torrenticola malarkeyorum groups with other members of the Rusetria Complex with high support and all specimens are less than 2% different in COI sequence from each other. In all analyses, T. malarkeyorum groups with two other morphologically similar species: T. biscutella and T. caerulea. These three species are 3–5% different from each other in COI sequence. The three of these species are morphologically similar to the more distantly-related T. delicatexa.

Based upon overall similarity, dorso-lateral platelet fusion, and distribution, we were able to place this species within the Eastern 2-Plate Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola manni are similar to members of the Miniforma group (T. copipalpa, T. miniforma, T. pacificensis, T. rockyensis, T. oliveri, and T. pinocchio) in having short, stocky pedipalps (except T. oliveri and T. pinocchio); similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. manni can be differentiated from all other Miniforma group by being from the southwest (all others are from the northwest or Rocky Mountains). T. manni are best differentiated from T. rockyensis by having more elongate pedipalp tibiae (length/width = 3.13–3.38 in T. manni, 2.47–3.11 in T. rockyensis). T. manni are best differentiated from T. copipalpa by having tuberculate pedipalp femoral extensions (broad and flat in T. copipalpa). T. manni are best differentiated from T. pacificensis by having more elongate tibiae (length/width = 3.24–3.38 in T. manni, 2.67–3.00 in T. pacificensis); having more elongate subcapitular rostra (length/width ♀ = 3.00–3.13 in T. manni, 2.59–2.68 in T. pacificensis; ♂ = 3.13–3.20 in T. manni, 2.76–3.07 in T. pacificensis).

Etymology

Specific epithet (manni) named in honor of author Charles Mann, whose books about the peopling of North America (e.g., 1491, 1493) breach history and venture into human ecology. They are an inspiration to confronting misconceptions and a reminder that even seemingly well-known history, whether archeological or evolutionary, is in fact usually not well-known. His books are a battle cry to never cease learning and to always question.

Remarks

Torrenticola manni groups with other members of the Miniforma Complex with high support and specimens of this species are less than 1% different in COI sequence from each other. In all analyses, T. manni groups with three other morphologically-similar species with high support: T. pacificensis, T. copipalpa, and T. rockyensis. These species are greater than 4% different from each other in COI sequence. These four species show a higher degree of biogeographic partitioning than most Torrenticola.

Based upon overall similarity, the pedipalp genu extensions, and western distribution, we were able to place this species in the Miniforma Identification Group.

This species hypothesis is supported by non-overlapping distribution, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola microbiscutella are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. sellersorum, T. tysoni, T. ululata, T. whitneyae, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. T. microbiscutella can be differentiated from all other Eastern 2-Plates by having an elongate dorsum (length/width = 1.63–1.75 in T. microbiscutella, 1.21–1.56 in others). T. microbiscutella can be differentiated from most other Eastern 2-Plates by having faint dorsal coloration (most other Eastern 2-Plates have bold coloration).

Etymology

Specific epithet (microbiscutella) is named because this species is the smallest (at least in females) and most elongate of all members of the Rusetria Complex (mikrós, G. small; bi, L. two; scutella, L. little plate).

Distribution

Southern Appalachians (Figure 143).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola microbiscutella and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution in the east, and fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and Eastern 2-Plate Identification Group.

Diagnosis

Torrenticola miniforma are similar to members of the Miniforma group (T. copipalpa, T. manni, T. pacificensis, T. rockyensis, T. oliveri, and T. pinocchio) in having short, stocky pedipalps (except T. oliveri and T. pinocchio); similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. miniforma are best differentiated from T. rockyensis by being smaller (dorsum length ♀ = 545 in T. miniforma, 570–620 in T. rockyensis; ♂ = 485 in T. miniforma, 525–545 in T. rockyensis); having more elongate subcapitular rostra (length/width ♀ = 3.13 in T. miniforma, 2.72–2.91 in T. rockyensis; ♂ = 3.19 in T. miniforma, 2.83–3.00 in T. rockyensis); and by being only known from Humboldt County, California, whereas T. rockyensis is distributed in the Rocky Mountains (Idaho & Montana). T. miniforma are best differentiated from T. copipalpa by having tuberculate pedipalp femoral extensions (broad and flat in T. copipalpa). T. miniforma are best differentiated from T. pacificensis by having more elongate anterio-medial platelets (length/width = 2.44–2.65 in T. miniforma, 2.00–2.16 in T. pacificensis); more elongate subcapitular rostra (length/width = 3.13–3.19 in T. miniforma, 2.59–3.07 in T. pacificensis); and by being only known from Humboldt County, California, whereas T. pacificensis is distributed in the Pacific Coast Ranges of Washington and Oregon. T. miniforma are best differentiated from T. manni by being smaller (dorsum length ♀ = 545 in T. miniforma, 565–620 in T. manni; ♂ = 485 in T. miniforma, 535–550 in T. manni); having stockier pedipalp tibiae (length/width = 2.38–2.88 in T. miniforma, 3.13–3.38 in T. manni); and by being only known from Humboldt County, California, whereas T. manni is only known from Catron County, New Mexico. T. miniforma can be differentiated from T. oliveri by having a shorter anterior venter (172–200 in T. miniforma, 250–310 in T. oliveri) and having less elongate pedipalpal tibiae (length/width = 2.3–2.9 in T. miniforma, 3.6–4.2 in T. oliveri). T. miniforma can be differentiated from T. pinocchio by having a less elongate rostrum (length/width = 3.1–3.2 in T. miniforma, 4.5–4.9 in T. pinocchio) and a more ovoid dorsum (length/width = 1.43–1.43 in T. miniforma, 1.53–1.64 in T. pinocchio).

Etymology

Habeeb (1974) did not specify an etymology for the specific epithet (miniforma). However, we suspect the specific epithet refers to the small body size of this species, as with others of the Miniforma Group (minor, L. small; forma, L. form), as Habeeb (1974) notes this species is “the smallest species that has come to the attention of the writer from the pacific area.”

Distribution

Known only from Prairie Creek, Humboldt County, California (Habeeb 1974) (Figure 146).

Remarks

Unfortunately, we were unable to acquire more specimens of Torrenticola miniforma and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with the type material. Based upon overall similarity, the pedipalp genu extensions, and western distribution, we were able to place this species in the Miniforma Complex and the Miniforma Identification Group.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (7 ♀; 7 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in the ACUA.

Diagnosis

Torrenticola mjolniri are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. longitibia, T. elusiva, T. racupalpa, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. mjolniri can be differentiated from T. elusiva, T. gnoma, and T. daemon by having more elongate pedipalp tibiae (length/width = 5.00–6.00 in T. mjolniri, 3.88–4.67 in others) and a more elongate rostrum (length/width = 3.81–4.32 in T. mjolniri, 2.56–3.65 in others). T. mjolniri can be differentiated from T. racupalpa by having a longer anterior venter (♀ = 180–195 in T. mjolniri, 152.5–165 in T. racupalpa; ♂ = 230–255 in T. mjolniri, 200–205 in T. racupalpa) and by dorsal pattern. T. mjolniri can be differentiated from T. irapalpa and T. danielleae by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.2–2.48 in T. mjolniri, 1.42–2.09 in others); having a more elongate rostrum (3.81–4.32 in T. mjolniri, 2.66–3.75 in others); and by dorsal pattern. Male T. mjolniri can be differentiated from T. longitibia (only males) by having Dgl-4 closer to the edge of dorsum (dorsal width/distance between Dgl-4 = 2.2–2.32 in T. mjolniri, 2.46–2.71 in T. longitibia); stockier pedipalp tibiae (length/width = 5.0–5.33 in T. mjolniri, 5.5–5.5 in T. longitibia); and a more elongate subcapitulum (ventral length/height = 2.82–3.0 in T. mjolniri, 2.68–2.73 in T. longitibia). T. mjolniri can be differentiated from T. raptor by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.2–2.48 in T. mjolniri, 1.68–2.02 in T. raptor) and a stockier subcapitulum (ventral length/width ♀ = 2.68–2.9 in T. mjolniri, 2.98–3.18 in T. raptor; ♂ = 2.82–3.0 in T. mjolniri, 3.13–3.27 in T. raptor). Additionally, female T. mjolniri have a shorter anterior venter (180–195 in ♀ T. mjolniri, 205–240 in ♀ T. raptor). Female T. mjolniri can be differentiated from female T. ivyae by having a larger dorsum (length ♀ = 605–640 in T. mjolniri, 550–590 in T. ivyae; width ♀ = 510–545 in T. mjolniri, 460–500 in T. ivyae) and a longer anterior venter (♀ 180–195 in T. mjolniri, 155–170 in T. ivyae). Male T. mjolniri can be differentiated from male T. ivyae by having a more elongate subcapitulum (ventral length/width = 2.82–3.00 in T. mjolniri, 2.57–2.75 in T. ivyae). Additionally, T. mjolniri can be differentiated from T. ivyae by being distributed in the northeast (T. ivyae is known from Florida).

Remarks

Torrenticola mjolniri groups with other members of the Raptor Complex with high support and all specimens are less than 2% different in COI sequence from each other. In all analyses, T. mjolniri groups with T. longitibia, and these species are more than 4% different in COI sequence from each other. The position of that clade varies with dataset. Based upon overall similarity, phylogenetic position, shape of the pedipalps, and distribution, we were able to place this species within the Raptor Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in the ACUA.

Diagnosis

Torrenticola mohawk are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. kringi, and T. dimorpha) in having a short, conical rostrum. T. mohawk are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, and T. kringi). T. mohawk can be differentiated from T. larvata, T. tricolor, T. cardia, and T. kringi by having a stockier rostrum (length/width ♀ = 1.80–2.00 in T. mohawk, 2.14–3.13 in others; ♂ = 2.00–2.13 in T. mohawk, 2.27–2.93 in others).

Etymology

Specific epithet (mohawk) named in honor of the Mohawk people (Kanien’kehá:ka), in reference to the dorsal coloration of this species, which resembles the hair-style by the same name (as a noun in apposition). The modern hairstyle does not exactly match traditional Mohawk styles, which resembled that of other tribes of the Iroquois Confederacy. Nevertheless, mohawks the hairstyle, which were originally associated with the Mohawk people in the historically problematic film Drums Along the Mohawk (1939), remains a symbol of the Mohawk people.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola mohawk and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution in the east, and short conical rostrum that is downturned in males, are consistent with placing this species in the Tricolor Complex and within the eastern clade of the Tricolor Identification Group.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (4 ♀; 3 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in ACUA.

Diagnosis

Torrenticola mulleni are similar to other members of the Rusetria “Western 2-Plates” group (T. nortoni, T. walteri, and T. welbourni) in having anterio-lateral platelets fused to the dorsal plate, having faint dorsal coloration, and being distributed in the west. Female T. mulleni can be differentiated from other female Western 2-Plates by having a longer medial suture (20–22.5 in T. mulleni, 10–12.5 in others). Male T. mulleni can be differentiated from other male Western 2-Plates by having a longer genital field (130–140 in T. mulleni, 112–125 in others). Additionally, T. mulleni can be differentiated from other Western 2-Plates by being distributed in the Rocky Mountains (Idaho, Montana, Utah and Wyoming) instead of California, Oregon and British Columbia.

Etymology

Specific epithet (mulleni) named in honor of Gary Mullen of Auburn University, who boldly devoted the entire second half of his Arachnology course to mites, and thus, in 2001, first introduced JRF to these creatures, sparking a life-long fascination.

Distribution

Rocky Mountain region (Figure 155).

Remarks

Torrenticola mulleni groups with other members of the Rusetria Complex with high support and specimens are less than 2% different in COI sequence from each other. In the all analyses, T. mulleni groups with the three other members of the Rusetria Complex that are found in western North America: T. nortoni, T. walteri, and T. welbourni. These species are 5–7% different in COI sequence from each other. T. mulleni is the only member of the Rusetria Complex that occurs throughout Rocky Mountains. Only T. walteri may overlap with this species in the northern Rockies of British Columbia; however, this overlap is speculative as T. mulleni was not found in any of our British Columbia samples. Young (1969) reported T. indistincta from Colorado, but we suspect this record represents T. mulleni.

Based upon overall similarity, the fusion of the posterio-lateral platelets to the dorsal shield, phylogenetic position, and distribution, we place this species within the Western 2-Plate Identification Group.

This species hypothesis is supported by non-overlapping distribution, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola multiforma are similar to other members of the Ellipsoidalis Group (T. ellipsoidalis, T. occidentalis, and T. leviathan), in being among the largest Torrenticola in the west (dorsum length ♀ = 700–885; ♂ = 665–850), although T. sierrensis are also large (dorsum length ♀ = 700–880; ♂ = 590–735) but can easily be distinguished from the Ellipsoidalis Group by being circular instead of ellipsoid or rectangular (dorsum length/width = 1.17–1.28 in T. sierrensis, 1.30–1.67 in Ellipsoidalis Group). T. multiforma are best differentiated from other members of the Ellipsoidalis Group by having more elongate subcapitular rostra (length/width = 2.5–2.8 in T. multiforma, 1.84–2.27 in other Ellipsoidalis Group).

Etymology

Habeeb (1974) did not specify an etymology for the specific epithet (multiforma). However, he notes that the males “vary a lot in size.” Thus, we suspect the specific epithet refers to the variable body size males of this species (multus, L. many; forma, L. form).

Distribution

Western (Figure 158). T. multiforma was previously known only from Prairie Creek, California (Habeeb 1974), but we expand its range to include most of western North America.

Remarks

Torrenticola multiforma groups other members of the Miniforma Complex with high support and specimens are 0–3% different in COI sequence. This is higher sequence variability than in many species hypotheses presented herein. However, given the topology in the COI tree (Figure 10) and morphological similarity, it seems apparent that the variability represents a continuum across a large distribution, rather than isolated species.

In all analyses, T. multiforma groups with T. ellipsoidalis and T. regalis, which are greater than 10% different from each other. Based upon overall similarity, body size, and distribution, we place this species within the Ellipsoidalis Identification Group.

This species hypothesis is supported by phylogenetic affinity, biogeography, high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola neoanomala are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba, and T. shubini), Elongata Group (T. elongata, T. gorti, and T. reduncarostra) and T. interiorensis, T. bondi, T. erectirostra, T. robisoni, T. irapalpa, T. racupalpa, T. skvarlai, and T. arktonyx. They can be differentiated from Rusetria 4-Plates and T. skvarlai by having distinct hind coxal margins. T. neoanomala can be differentiated from T. erectirostra and T. robisoni by having a straight, anteriorly-directed rostrum (upturned in T. erectirostra and T. robisoni). T. neoanomala can be differentiated from T. arktonyx by having an unmodified dorsal plate (T. arktonyx has distinctive longitudinal dark markings on the anterior portion of the dorsal plate that fade posteriorly). T. neoanomala can be differentiated from T. racupalpa and T. irapalpa by having more elongate anterio-lateral platelets (length/width = 2.79–3.23 in T. neoanomala, 2.17–2.67 in others) and Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.37–1.5 in T. neoanomala, 1.58–2.77 in others). T. neoanomala can be differentiated from Elongata Group by being slightly more ovoid (dorsum length/width ♀ = 1.35–1.43 in T. neoanomala, 1.45–2.08 in Elongata Group; ♂ = 1.43–1.50 in T. neoanomala, 1.51–1.7 in Elongata Group) and having a stockier rostrum (length/width = 2.59–2.90 in T. neoanomala, 3.24–4.00 in Elongata Group). T. neoanomala can be differentiated from T. bondi by having a longer medial suture (♀ = 22–40 in T. neoanomala, 10–15 in T. bondi; ♂ = 95–108 in T. neoanomala, 55–70 in T. bondi) and by anterior venter/genital field width (♀ = 1.39–1.45 in T. neoanomala, 1.15–1.25 in T. bondi; ♂ = 2.42–2.66 in T. neoanomala, 1.95–2.05 in T. bondi). Female T. neoanomala can be differentiated from female T. interiorensis by having more elongate anterio-lateral platelets (length/width = 2.86–3.09 in T. neoanomala, 2.62–2.67 in T. interiorensis). Male T. neoanomala can be differentiated from male T. interiorensis by having a longer anterior venter (267.5–290 in T. neoanomala, 220–240 in T. interiorensis) and a longer genital field (145–160 in T. neoanomala, 132–138 in T. interiorensis).

Etymology

Habeeb (1957) did not specify an etymology for the specific epithet (neoanomala). In fact, Habeeb (1955) initially identified the specimens as the Palaearctic T. anomala, but later (1957) writes, “The mite I reported as Torrenticola anomala (Koch) is now seen to be distinct from this European form.” So, this name surely refers to the similarity of this species to the T. anomala (Koch, 1837) (néos, G. new).

Distribution

T. neoanomala was previously known only from Albert County, New Brunswick, but we extend its range throughout eastern North America (Figure 161). Records from Shackelford County, Texas, make T. neoanomala one of the few eastern Torrenticola that are found in the Great Plains.

Remarks

Torrenticola neoanomala groups with other members of the Raptor Complex with high support and specimens are less than 2.5% different in COI sequence from each other. In the combined analysis, T. neoanomala groups with the superficially similar T. interiorensis, and specimens from these species are greater than 9% different in COI sequence from each other.

Based upon this relationship and their similarity, we place these species in the Neoanomala Identification Group. The Neoanomala Group shares a phylogenetic affinity for members of the similar-looking Erectirostra Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola nigroalba are similar to other members of the Nigroalba Group (T. flangipalpa, T. solisorta, T. dentirostra) in being small, slightly elongate, having purple dorsal coloration restricted posteriorly, and having distinct yet poorly-defined hind coxal margins. T. nigroalba can be differentiated from T. flangipalpa in having tuberculate pedipalp femoral extension (flange-like and anteriorly-directed in T. flangipalpa); a shorter anterior venter (200–223 in T. nigroalba, 235–265 in T. flangipalpa); and more elongate pedipalpal tibiae (length/ width ♀ = 5.38–5.83 in T. nigroalba, 4.79–5.00 in T. flangipalpa; ♂ = 5.08–5.33 in T. nigroalba, 4.40–4.86 in T. flangipalpa). T. nigroalba can be differentiated from T. dentirostra by having a smooth rostrum (T. dentirostra has a dentate bump midway on the dorsal edge of the rostrum) and by having more elongate pedipalpal tibiae (length/width ♀ = 5.3–5.9 in T. nigroalba, 4.5–5.0 in T. dentirostra; ♂ = 5.0–5.4 in T. nigroalba, 4.5–4.7 in T. dentirostra). T. nigroalba can be differentiated from T. solisorta by lacking orangish coloration immediately anterior to the purple dorsal coloration, although rarely specimens have been found with this coloration. Female T. nigroalba are also slightly larger (500–530 in T. nigroalba, 475–500 in T. solisorta); have a thinner gnathosomal bay (length/width = 1.25–1.55 in T. nigroalba, 1.3–1.5 in T. solisorta); and have a slightly thicker subcapitulum (3.00–3.14 in T. nigroalba, 3.14–3.30 in T. solisorta). Male T. nigroalba also have a longer medial suture with respect to the anterior venter (anterior venter/medial suture = 2.54–2.77 in T. nigroalba, 2.87–3.26 in T. solisorta) and a thinner dorsum (290–300 in T. nigroalba, 305–320 in T. solisorta). Other Torrenticola with purple dorsal coloration restricted posteriorly can be confused with T. nigroalba, such as T. tahoei and T. oregonensis. Both of these species are larger (dorsum length ♀ = 500–530 in T. nigroalba, 600–810 in others; ♂ = 440–455 in T. nigroalba, 560–820 in others) and distributed in the west (T. nigroalba is eastern).

Immatures unknown.

Etymology

Habeeb (1955) did not specify an etymology for the specific epithet (nigroalba). However, surely this name refers to the dorsal coloration being half pigmented (purple) and half unpigmented (yellow), although Habeeb (1955) identified these colors as black and white (niger, L. black; albus, L. white).

Distribution

Northeastern and southward throughout the Appalachians (Figure 164). T. nigroalba was previously known only from Albert County, New Brunswick; we extend its distribution throughout the Appalachians and into Ottawa.

Remarks

Torrenticola nigroalba groups with other members of the Raptor Complex with high support in all analyses and specimens are less than 1% different in COI sequence from each other. In all analyses, T. nigroalba groups with two other morphologically similar species: T. flangipalpa and T. solisorta. These three species are greater than 12% different from each other in COI sequence. That clade of three species corresponds to an identification group, the Nigroalba Group, the members of which are easily differentiated by their size, coloration, long medial suture in females, and overall appearance.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola nortoni are similar to other members of the Rusetria “Western 2-Plates” group (T. mulleni, T. walteri, and T. welbourni) in having anterio-lateral platelets fused to the dorsal plate, having faint dorsal coloration (some are colorless), and being distributed in the west. Female T. nortoni can be differentiated from T. welbourni (female only known) by having stockier pedipalp tibiae (3.13–3.33 in A33, 3.73 in A30) and shorter pedipalp femora (112.5–122.5 in A33, 137.5 in A30). Female T. nortoni can be differentiated from female T. mulleni by having a shorter medial suture (10–12.5 in A33; 20–22.5 in A31) and a shorter genital field (177.5–192.5 in A33, 195–205 in A31). Male T. nortoni can be differentiated from male T. mulleni by having shorter pedipalp femora (85–93 in T. nortoni, 97–103 in T. mulleni). Additionally, T. nortoni can be differentiated from T. mulleni by being distributed in California, instead of in the Rocky Mountains (Idaho, Montana, Utah and Wyoming). Female T. nortoni can be differentiated from female T. walteri by having slightly longer pedipalp femora with respect to genua (1.69–1.82 in T. nortoni, 1.52–1.64 in T. walteri) and slightly more elongate anterio-medial platelets (2.74–3.06 in T. nortoni, 2.58–2.72 in T. walteri). Male T. nortoni can be differentiated from male T. walteri by having longer pedipalp femora (85–92.5 in T. nortoni, 95–100 in T. walteri) and slightly more elongate pedipalp tibiae (2.73–3.0 in T. nortoni, 3.05–3.10 in T. walteri).

Etymology

Specific epithet (nortoni) named in honor of acarologist Roy Norton who taught JRF oribatids during the Soil Mite Course at The Ohio State University Acarology Summer Program; specifically for his talent in weaving biological stories into his lessons.

Distribution

California (Figure 167).

Remarks

Torrenticola nortoni groups with other members of the Rusetria Complex with high support and specimens are less than 2% different in COI sequence from each other. In the all analyses, T. mulleni groups with the three other members of the Rusetria Complex that are found in western North America: T. mulleni, T. walteri, and T. welbourni. These species are 5–7% different in COI sequence from each other and together make up the Western 2-Plate Identification Group. Torrenticola nortoni is one of three of these that occur in California (including T. walteri and T. welbourni).

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Material examined

HOLOTYPE (♀): from USA, Wyoming, Medicine Bow National Forest, 1928, by JW Scott, RM280072.

Type deposition

Holotype (♀) deposited in the CNC.

Diagnosis

Torrenticola occidentalis are similar to other members of the Ellipsoidalis Group (T. ellipsoidalis, T. multiforma, and T. leviathan), and in being among the largest Torrenticola in the west (dorsum length ♀ = 700–885; ♂ = 665–850), although T. sierrensis are also large (dorsum length ♀ = 700–880; ♂ = 590–735) but can easily be distinguished from the Ellipsoidalis Group by being circular instead of ellipsoid or rectangular (dorsum length/width = 1.17–1.28 in T. sierrensis, 1.30–1.67 in Ellipsoidalis Group). T. occidentalis can be differentiated from T. ellipsoidalis by having a shorter medial suture (20 in T. occidentalis, 40–57.5 in T. ellipsoidalis) and by having more elongate anterio-lateral platelets (length/width = 2.54 in T. occidentalis, 2.00–2.39 in T. ellipsoidalis). T. occidentalis can be differentiated from T. multiforma by having stockier subcapitular rostra (length/width = 2.15 in T. occidentalis, 2.5–2.8 in T. multiforma). T. occidentalis can be differentiated from T. leviathan by having less elongate pedipalpal tibiae (length/width = 3.33 in T. occidentalis, 3.43–4.20 in T. leviathan) and a shorter dorsum (length ♀ = 770 in T. occidentalis, 845–870 in T. leviathan).

Immatures unknown.

Etymology

Marshall (1933) did not specify an etymology for the specific epithet (occidentalis). However, surely this name refers to the type locality of this species in western United States (occidens, L. direction of the setting sun, west).

Distribution

Known only from South-central Wyoming (Medicine Bow National Forest) (Figure 170), from a single female collected from trout stomach contents.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola occidentalis and therefore this species is not included in our phylogenetic analyses. However, we were able to examine the holotype. Based upon overall similarity and a short, conical rostrum, we place this species in the Miniforma Complex and the Ellipsoidalis Identification Group

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 2 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola oliveri are similar to members of the Miniforma group (T. copipalpa, T. manni, T. miniforma, T. pacificensis, T. rockyensis, and T. pinocchio) in having similar pedipalpal extensions (unique to members of this group). T. oliveri can be differentiated from all other members of Miniforma Complex by having a longer anterior venter (250–310 in T. oliveri, 173–235 in others) and more elongate pedipalpal tibiae (length/width = 3.68–4.13 in T. oliveri, 2.47–3.50 in others).

Etymology

Specific epithet (oliveri) named in honor of comedian John Oliver and his team, whose commentary on Last Week Tonight breaches the realm of comedy and enters journalism. News and politics, like science, require both challenging misinformation and effectively communicating those challenges—tasks Oliver has humbly mastered.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola oliveri and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, small size, distribution, and distinctive flange on pedipalpal genua place this species in the Miniforma Identification Group within the Miniforma Complex.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (5 ♀; 6 ♂) deposited in the CNC; other paratypes (4 ♀; 5 ♂) deposited in the ACUA.

Diagnosis

Torrenticola olliei are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. sierrensis, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. olliei can be differentiated from most Torrenticola, including most other members of the Tricolor Complex, by having a very short rostrum (length/width = 1.56–1.81 in T. olliei, 1.80–3.13 in others), except T. bittikoferae (1.81–1.9) and T. dimorpha (1.3–1.6). Additionally, males have a shorter anterior venter than all other Tricolor Complex (♂ = 205–225 in T. olliei, 230–335 in others), except T. kringi (220–255), and both males and females have a wider genital field than most other Tricolor Complex (♀ = 190–202.5 in T. olliei, 145–180 in others; ♂ = 130–137.5 in T. olliei, 92.5–120 in others) except for T. sierrensis (♀ = 180–212.5; ♂ = 135–175) and female T. leviathan (180–195). Finally, T. olliei can be differentiated from most Tricolor Complex, except for T. sierrensis, by being distributed in the west (all others are eastern).

Etymology

Specific epithet (olliei) named in honor of Ollie—pet Boston Terrier of JRF and DMF—whose brachycephaly resembles the short rostrum of this species, the shortest of all Torrenticola.

Distribution

Pacific coastal mountains (Figure 175).

Remarks

Torrenticola olliei groups with other members of the Tricolor Complex with high support in all analyses and group with T. sierrensis to form the western portion of this complex. Only one specimen was analyzed phylogenetically, so intraspecific variation remains unknown, but that specimen is greater than 6% different from all specimens of T. sierrensis. This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola oregonensis are similar to the other member of Tahoei group, T. tahoei by subcapitulum shape, having purple coloration restricted posteriorly and being distributed in the west and to members of the Nigroalba Group (T. flangipalpa, T. nigroalba, T. solisorta, and T. dentirostra) in having purple dorsal coloration restricted posteriorly. T. oregonensis can be differentiated from the Nigroalba Group by being larger (dorsum length ♀ = 760–840 in T. oregonensis, 475–565 in Nigroalba Group; ♂ = 690–820 in T. oregonensis, 425–510 in Nigroalba Group) and distributed in Oregon (Nigroalba Group are eastern). T. oregonensis can be differentiated from T. tahoei by being larger (dorsum length ♀ = 760–840 in T. oregonensis, 600–720 in T. tahoei; ♂ = 690–820 in T. oregonensis, 560–650 in T. tahoei; dorsum width ♀ = 560–640 in T. oregonensis, 430–515 in T. tahoei; ♂ = 520–605 in T. oregonensis, 400–460 in T. tahoei) and a less elongate subcapitulum (ventral length/width = 2.63–2.74 in T. oregonensis, 3.25–4.11 in T. tahoei).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola oregonensis and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. Due to its unique set of characteristics, we are unable to place this species into a species group or complex.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (29 ♀; 325♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola pacificensis are similar to members of the Miniforma group (T. copipalpa, T. manni, T. miniforma, T. rockyensis, T. oliveri, and T. pinocchio) in having short, stocky pedipalps (except T. oliveri and T. pinocchio); similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. pacificensis are best differentiated from T. rockyensis by females having a stockier rostrum (length/width ♀ = 2.59–2.68 in T. pacificensis, 2.72–2.91 in T. rockyensis); and by being distributed in the Pacific Coast Ranges of Washington and Oregon instead of the Rocky Mountains (Idaho & Montana). T. pacificensis are best differentiated from T. copipalpa by having tuberculate pedipalp femoral extensions (broad and flat in T. copipalpa) and by being distributed in the Pacific Coast Ranges of Washington and Oregon, whereas although T. pacificensis overlap, they are more southern (southwest Oregon & California). T. pacificensis are best differentiated from T. manni by having stockier tibiae (length/width = 2.67–3.00 in pacificensis, 3.13–3.38 in T. manni); having a stockier rostrum (length/width ♀ = 2.59–2.68 in T. pacificensis, 3.00–3.13 in T. manni; ♂ = 2.76–3.07 in T. pacificensis, 3.13–3.20 in T. manni); and by being distributed in the Pacific Coast Ranges of Washington and Oregon, whereas T. manni is only known from Catron County, New Mexico. T. pacificensis are best differentiated from T. miniforma by having stockier anterio-medial platelets (length/width = 2.00–2.16 in T. pacificensis, 2.44–2.65 in T. miniforma); stockier subcapitular rostra (length/width = 2.59–3.07 in T. pacificensis; 3.13–3.19 in T. miniforma); and by being distributed in the Pacific Coast Ranges of Washington and Oregon, whereas T. miniforma is only known from Humboldt County, California. T. pacificensis can be differentiated from T. oliveri by having a shorter anterior venter (177–235 in T. pacificensis, 250–310 in T. oliveri) and less elongate pedipalpal tibiae (length/width = 2.6–3.0 in T. pacificensis, 3.6–4.2 in T. oliveri). T. pacificensis can be differentiated from T. pinocchio by having a less elongate rostrum (length/width = 2.5–3.1 in T. pacificensis, 4.5–4.9 in T. pinocchio) and less elongate pedipalpal tibiae (length/width = 2.67–3.00 in T. pacificensis, 3.13–3.50 in T. pinocchio).

Etymology

Specific epithet (pacificensis) refers to the distribution of this species in the Pacific Ranges of the Pacific Northwest. This location-based name reflects that locality is the best way to differentiate this species from others in the Miniforma Group, particularly T. rockyensis.

Distribution

Western Oregon and western Washington (Figure 181). It seems reasonable to suspect T. pacificensis also occurs in coastal British Columbia and northwestern California.

Remarks

Torrenticola pacificensis groups with other members of the Miniforma Complex with high support and specimens of this species are less than 1% different in COI sequence from each other. In all analyses, T. pacificensis groups with three other morphologically similar species: T. rockyensis, T. manni, and T. copipalpa. These three species are greater than 4% different from each other in COI sequence. This species overlaps with T. copipalpa in west-central Oregon, but is the only member of the Miniforma group that occurs north of that point of overlap.

Based upon overall similarity, the pedipalp genu extensions, and western distribution, we were able to place this species in the Miniforma Identification Group.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola pearsoni are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. pearsoni can be differentiated from most other Tricolor Complex (except T. bittikoferae, T. hoosieri and T. dimorpha) by having diffuse pink dorsal coloration, whereas most other members have bold patterning. T. pearsoni can be differentiated from T. hoosieri by having ventral extensions on the pedipalp femora and genua (lacking in T. hoosieri) and having stockier pedipalp tibiae (length/width = 3.0–3.3 in T. pearsoni, 3.6–4.4 in T. hoosieri). Male T. pearsoni can be differentiated from T. bittikoferae (males only) by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.2–1.3 in T. pearsoni, 1.6–1.7 in T. bittikoferae); more elongate pedipalp tibiae (length/width = 3.1–3.3 in T. pearsoni, 2.7–2.8 in T. bittikoferae); and a more elongate rostrum (length/width = 2.1–2.4 in T. pearsoni, 1.8–1.9 in T. bittikoferae). T. pearsoni can be differentiated from T. dimorpha by having an unmodified dorsal plate (T. dimorpha has a dorsal plate medial extension covering nearly half the length of the anterio-medial platelets) and by males having unmodified pedipalps (male T. dimorpha have large, highly modified pedipalps which are expanded vertically and laterally).

Remarks

Torrenticola pearsoni groups with other members of the Tricolor Complex in all analyses with high support and specimens are less than 2% different in COI sequence from each other. In the combined analysis, T. pearsoni groups with two other species (T. hoosieri and T. projector) with high support and these species are greater than 11% different from each other. Whereas most eastern members of the Tricolor Complex have distinctive patterns, this clade of three species contains members that lack dark patterns.

This species hypothesis is supported by low COI divergence within the species (0–2%), high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂) deposited in the CNC; paratype (1 ♀) deposited in the ACUA.

Diagnosis

Torrenticola pendula are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. sellersorum, T. tysoni, T. ululata, T. whitneyae, T. microbiscutella, T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. It is one of only four Eastern 2-Plates that have dark, bold, bluish-purple coloration (also T. tysoni, T. biscutella, and T. sellersorum). T. pendula can be differentiated from other Eastern 2-Plates (except T. whitneyae and T. feminellai) by having a more elongate gnathosomal bay (2.42–2.9 in T. pendula, 1.4–2.24 in others) and often by having a dorsal pattern of dark bluish-purple separated into anterior and posterior portions connected medially. In the Rusetria Complex only T. whitneyae and T. magnexa (rarely) has a similar pattern. T. pendula can be differentiated from T. magnexa by having anterio-medial platelets fully fused to the dorsal plate (anterio-lateral platelets partially fused to the dorsal plate in T. magnexa). T. pendula can be differentiated from T. whitneyae by having a more elongate rostrum (length/width = 2.87–3.06 in T. pendula, 2.41–2.69 in T. whitneyae). T. pendula can be differentiated from T. feminellai by having less elongate pedipalpal tibiae (length/width = 2.78-3.05 in T. pendula; 3.63–4.11 in T. feminellai).

Remarks

Torrenticola pendula groups with other members of the Rusetria Complex with high support. The two specimens (one male and one female) are 6.7% different in COI sequence from each other, suggesting each represents a separate species. However, in addition to similar overall appearance and occurring in the same sample, they also are indistinguishable in characters that are not usually sexually dimorphic (e.g., pedipalp proportions). Because of this, we consider these two specimens as the same species, despite the high COI variability.

In all analyses, T. pendula groups with other eastern members of the Rusetria Complex that have posterio-lateral platelets fused with the dorsal shield, but in both analyses the position of this species within that clade was not well-supported. This species was 17–18% different in COI sequence from sister species.

Based upon overall similarity, fusion of the lateral platelets with the dorsal shield, phylogenetic position, and distribution, we were able to place this species in the Eastern 2-Plate Identification Group.

This species hypothesis is supported by phylogenetic affinity, high divergence between species (17–18%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola pinocchio are similar to members of the Miniforma group (T. copipalpa, T. manni, T. miniforma, T. pacificensis, T. rockyensis, and T. oliveri) in having similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. pinocchio can be differentiated from all other Torrenticola by having a more elongate rostrum (length/width = 4.58–3.91 in T. pinocchio, 1.29–4.40 in others).

Etymology

Specific epithet (pinocchio) refers to the elongate rostrum of this species, which resembles the ever-growing nose of Pinocchio (noun in apposition), a fictional character from the popular Italian children’s novel, The Adventures of Pinocchio by Carlo Collodi (1883). Pinocchio is well-known for his nose, which grows every time he tells a lie.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola pinocchio and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, small size, dentate flange on the pedipalpal genua, and distribution, are consistent with placing this species in the Miniforma Complex and Miniforma Identification Group.

Type deposition

Holotype (♀), allotype (♂), and other paratypes (2 ♀; 5 ♂) deposited in the CNC; other paratypes (2 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola pollani are similar to other members of the Rusetria “4-Plates” group (T. dunni, T. glomerabilis, T. kittatinniana, T. rufoalba, and T. shubini) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. T. pollani can be differentiated from T. dunni by having a smaller dorsum (length ♀ = 535–560 in T. pollani, 605–680 in T. dunni; ♂ = 440–490 in T. pollani, 500–540 in T. dunni; width ♀ , 410–420 in T. pollani, 440–490 in T. dunni; ♂ = 350–370 in A38, 310–340 in T. pollani); and a more elongate rostrum (length/width = 3.3–3.8 in T. pollani, 2.8–3.1 in T. dunni). T. pollani can be differentiated from T. shubini by having more elongate tibiae (length/width ♀ = 4.00–4.18 in T. pollani, 3.35–3.60 in T. shubini; ♂ = 3.44–3.75 in T. pollani, 3.11–3.22 in T. shubini) and a more elongate rostrum (length/width = 3.27–3.82 in T. pollani, 2.24–2.85 in T. shubini). T. pollani can be differentiated from T. glomerabilis by having more elongate anterio-medial platelets (length/width ♀ = 2.5–3.0 in T. pollani, 1.9–2.3 in T. glomerabilis; ♂ = 2.3–2.5 in T. pollani, 1.9–2.2 in T. glomerabilis) and thinner dorsum (♀ = 410–420 in T. pollani, 460–490 in T. glomerabilis; ♂ = 310–340 in T. pollani, 395–430 in T. glomerabilis). T. pollani can be differentiated from T. kittatinniana by having a more elongate rostrum (length/width = 3.27–3.82 in T. pollani, 2.71–3.16 in T. kittatinniana) and more elongate tibiae (length/width ♀ = 3.8–4.2 in T. pollani, 3.3 in T. kittatinniana; ♂ = 3.44–3.75 in T. pollani, 2.80 in T. kittatinniana). T. pollani can be differentiated from T. rufoalba by having a more elongate rostrum (length/width = 3.27–3.82 in T. pollani, 2.96–3.06 in T. rufoalba). Female T. pollani can be differentiated from female T. rufoalba by having more elongate tibiae (length/width = 3.8–4.2 in T. pollani, 3.5 in T. rufoalba). Male T. pollani can be differentiated from male T. rufoalba by having a longer anterior venter (235–250 in T. pollani, 195 in T. rufoalba). T. pollani can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle, and by having a longer anterior venter (♀ = 155–163 in T. pollani, 140–153 in T. skvarlai; ♂ = 235–250 in T. pollani, 177.5–205 in T. skvarlai).

Etymology

Specific epithet (pollani) named in honor of author Michael Pollan, whose influential books breach mere accounts on food culture and enter insightful discussions of human ecology.

Remarks

In all analyses, Torrenticola pollani groups with other members of the Rusetria Complex with high support and specimens of this species are less than 1% different in COI sequence from each other. In all analyses, Torrenticola pollani groups with two other species with high support: T. dunni and T. shubini. These species are greater than 5–10% different from each other in COI sequence. Given our collection efforts in the southern Appalachians, it is reasonable to speculate that T. pollani does not overlap in range with either T. dunni or T. shubini. However, our collections are sparse in the coastal plains and we expect future collecting to expand the distribution southward.

Based upon overall similarity, dorso-lateral platelet fusion, and distribution, we were able to place this species within the Eastern 2-Plate Identification Group

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola priapus are similar to other members of the Partial 2-Plate Group (T. folkertsae, T. magnexa, and T. pulchra) in having anterio-lateral platelets partially fused to the dorsal plate and being distributed in the east. T. priapus can be differentiated from T. magnexa and T. pulchra by dorsal coloration and pattern. T. priapus can be further differentiated from T. magnexa by having a more elongate rostrum (length/width = 3.17–3.39 in T. priapus, 2.25–3.00 in T. magnexa). T. priapus can be further differentiated from T. pulchra by having a round dorsum (length/width = 1.18–1.22 in T. priapus, 1.4–1.61 in T. pulchra) and more elongate pedipalpal tibiae (length/width ♀ = 3.9–4.22 in T. priapus, 3.3–3.70 in T. pulchra, ♂ = 3.5–3.78 in T. priapus, 3.00–3.35 in T. pulchra). T. priapus can be differentiated from T. folkertsae by having less elongate pedipalpal tibiae (length/width ♀ = 3.9–4.22 in T. priapus, 4.5–4.83 in T. folkertsae, ♂ = 3.5–3.78 in T. priapus, 4.05–4.33 in T. folkertsae) and a more elongate rostrum (length/width = 3.17–3.39 in T. priapus, 2.55–3.00 in T. folkertsae).

Etymology

Specific epithet (priapus) is named for Priapus, the Greek fertility god who was marked by his oversized, permanent erection, which refers to the genital opening in the male—the largest of all North American Torrenticola.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola priapus and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution, and partial fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and within the Partial 2-Plate Identification Group.

Diagnosis

Torrenticola projector are unlike nearly all other Torrenticola in having such elongate bodies and subcapitula. T. elongata are also elongate, but have different dorsal coloration and do not have an elongate subcapitulum. T. tahoei also have elongate subcapitula, but have rounder bodies with different dorsal coloration. T. anoplopalpa also have elongate subcapitula, but have rounder bodies and incomplete hind coxae.

Etymology

Habeeb (1961) did not specify an etymology for the specific epithet (projector). However, surely this name reflects the elongated, projectable gnathosoma (proiectus, L. stick out)

Distribution

Appalachians (Figure 199). T. projector was previously known only from New York; we extend its range throughout the Appalachians.

Remarks

Torrenticola projector groups with other members of the Tricolor Complex in all analyses with high support and specimens are less than 1% different in COI sequence from each other. In the combined analysis, T. projector groups with two other species (T. hoosieri and T. pearsoni) with high support and these species are greater than 4% different from each other. Whereas most eastern members of the Tricolor Complex have distinctive patterns, this clade of three species contains members that lack dark patterns. T. projector is among the most distinctive of all Torrenticola because of the highly elongated gnathosoma and body. Because of this distinctive morphology, we do not place this species into an identification group.

This species hypothesis is supported by low COI divergence within the species (0–2%), high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola pulchra are similar to other members of the Partial 2-Plate Group (T. folkertsae, T. magnexa, and T. priapus) in having anterio-lateral platelets partially fused to the dorsal plate and being distributed in the east. T. pulchra can be differentiated from other Partial 2-Plate Group by dorsal coloration and pattern. T. pulchra can be further differentiated from T. priapus and T. folkertsae by having a more ovoid dorsum (length/width = 1.4–1.61 in T. pulchra, 1.11–1.29 in others) and less elongate pedipalpal tibiae (length/width ♀ = 3.3–3.70 in T. pulchra, 3.9–4.83 in others, ♂ = 3.00–3.35 in T. pulchra, 3.5–4.33 in others). Male T. pulchra can be further differentiated from male T. magnexa by having a smaller genital field (length ♂ = 110–123 in T. pulchra, 125–148 in T. magnexa; width ♂ = 87–95 in T. pulchra, 115–125 in T. magnexa,) and less elongate pedipalpal tibiae (length/width ♂ = 3.00–3.35 in T. pulchra, 3.78–4.00 in T. magnexa,). Female T. pulchra can be differentiated from female T. magnexa by having a thinner genital field (♀ 147–160 in T. pulchra, 170–188 in T. magnexa) and shorter pedipalpal tibiae (♀ 82–93 in T. pulchra, 102–113 in T. magnexa).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola pulchra and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution, and partial fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and within the Partial 2-Plate Identification Group.

Diagnosis

Torrenticola racupalpa are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. longitibia, T. mjolniri, T. elusiva, T. raptor, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. Female T. racupalpa can be differentiated from T. elusiva by having a more elongate subcapitulum (ventral length/height = 2.48–2.73 in T. racupalpa, 2.39 in T. elusiva); and by dorsal pattern. T. racupalpa can be differentiated from T. irapalpa and T. daemon by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.19–2.77 in T. racupalpa, 1.45–2.09 in others) and a more elongate rostrum (length/width = 3.56–3.88 in T. racupalpa, 2.66–3.39 in others). T. racupalpa can be differentiated from T. gnoma by having a more elongate rostrum (length/width = 3.56–3.88 in T. racupalpa, 2.56–3.13 in T. gnoma) and dorsal coloration and pattern. T. racupalpa can be differentiated from T. mjolniri by having a shorter anterior venter (♀ =152.5–165 in T. racupalpa, 180–195 in T. mjolniri; ♂ = 200–205 in T. racupalpa, 230–255 in T. mjolniri); and by dorsal pattern. Male T. racupalpa can be differentiated from T. longitibia (males only) by having a shorter femur with respect to the genu (femur/genu = 1.92–1.92 in T. racupalpa, 2.10–2.17 in T. longitibia); a stockier rostrum (length/width = 3.88–3.88 in T. racupalpa, 4.15–4.23 in T. longitibia); and dorsal pattern. T. racupalpa can be differentiated from T. raptor by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.19–2.77 in T. racupalpa, 1.68–2.02 in T. raptor); and shorter anterior venter (♀ = 152.5–165 in T. racupalpa, 205–240 in T. raptor, ♂ = 200–205 in T. racupalpa, 245–305 in T. raptor). Female T. racupalpa can be differentiated from female T. raptor by having stockier pedipalp tibiae (length/width = 4.44–5.00 in T. racupalpa, 6–7.54 in T. raptor). T. racupalpa can be differentiated from T. danielleae by having Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 2.19–2.77 in T. racupalpa, 1.42–1.70 in T. danielleae) and by dorsal coloration and pattern. Female T. racupalpa can be differentiated from female T. ivyae by having a less elongate rostrum (length/width = 3.56–3.82 in T. racupalpa, 4.00–4.15 in T. ivyae) and less elongate pedipalpal tibiae (length/width = 4.44–5.00 in T. racupalpa, 5.07–5.64 in T. ivyae). Male T. racupalpa can be differentiated from male T. ivyae by having a shorter anterior venter (♂ 200–205 in T. racupalpa, 220–230 in T. ivyae) and a longer genital field (♂ 160–165 in T. racupalpa, 142–148 in T. ivyae).

Remarks

In the COI analysis, Torrenticola racupalpa groups with other members of the Raptor Complex with high support. We were only able to acquire molecular data from one specimen, and we were unable to amplify 28S, which disabled us from examining the placement of this species in our combined analysis. In the COI analysis, T. racupalpa groups with T. elusiva with high confidence, and these species are greater than 4% different in COI sequence from each other. Based upon this information as well as morphology, we place this species in Raptor Identification Group.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola rala are similar to other members of the Rala Group (T. boettgeri, T. keesdavidsi, T. kurtvietsi, T. lamellipalpis, T. dolichodactyla, and T. anoplopalpa) by being colorless, having incomplete hind coxal margins and being distributed in the southwest. T. rala can be differentiated from all other Rala Group by having a stockier rostrum (length/width = 1.63–1.83 in T. rala, 2.19–3.57 in others). Additionally, T. rala can be differentiated from all other Rala Group by having a shorter anterior venter (♀ = 170–185 in T. rala 192–260 in others ♂ = 200–225 in T. rala, 235–308 in others), except male T. keesdavidsi (♂ 225–260).

Remarks

Our analyses were unable to confidently place Torrenticola rala phylogenetically. The COI analyses recovers this species at the base of the Raptor Complex, but this relationship was not recovered in the combined analysis. Because of this ambiguity, we refrain from placing this species in a species complex. However, based upon the morphological similarity that this species shares with six other species, we place this species within the Rala Identification Group.

T. rala is greater than 13% different in COI sequence from sister species. This species hypothesis is supported by high divergence between species (3–15%) and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (53 ♀; 34 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola raptor are similar to other members of the Raptor Group (T. gnoma, T. irapalpa, T. longitibia, T. mjolniri, T. elusiva, T. racupalpa, T. danielleae, T. daemon, and T. ivyae) in having round bodies; Dgl-4 close to muscles scars; long, thin subcapitular rostra; and long, thin pedipalp tibiae. T. raptor can be differentiated from all other members of the Raptor Group by having a more elongate subcapitulum (ventral length/height ♀ = 2.98–3.18 in T. raptor, 2.26–2.90 in others; ♂ = 3.13–3.27 in T. raptor, 2.29–3.00 in others). T. raptor can be further differentiated from T. elusiva, T. irapalpa, T. gnoma, T. danielleae, T. daemon, and T. ivyae by having more elongate pedipalp tibiae (length/width ♀ = 6.00–7.54 in T. raptor, 4.09–5.67 in others; ♂ = 5.29–5.63 in T. raptor, 3.88–5.20 in others). T. raptor can be further differentiated from T. mjolniri, T. longitibia, T. gnoma, T. elusiva, T. racupalpa, and T. ivyae by having Dgl-4 closer to the dorsal edge (dorsal width/distance between Dgl-4 = 1.66–2.02 in T. raptor, 2.06–3.29 in others).

Etymology

Specific epithet (raptor) refers to the long, thin pedipalps (especially tibiae) of this species which, combined with pronounced tubercles, appear especially capable of grasping slippery prey (rapio L. to seize; known in apposition).

Distribution

Northeastern, but extending southward in the Appalachians (Figure 211).

Remarks

Torrenticola raptor groups with other members of the Raptor Complex with high support and specimens of this species are less than 4% different in COI sequence from each other. This is higher sequence variability than in many species hypotheses presented herein. However, given the topology in the COI tree (Figure 7) and morphological similarity, it seems apparent that the variability represents a continuum across a large distribution rather than isolated species, so we consider these specimens to be within the same species hypothesis.

The position of T. raptor varied with analysis and was not well-supported in the combined analysis, so we are unable to comment on its affinities. However, morphological similarity is consistent with placing this species in the Raptor Identification Group.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Remarks

Our analyses were unable to confidently place Torrenticola raptoroides phylogenetically. Both analyses place this species at the base of the Raptor Complex, but this relationship was not well-supported. Because of this ambiguity, we refrain from placing this species in a species complex. Furthermore, because of the unique morphology, we are also unable to place this species within an identification group.

All specimens are less than 1% different in COI sequence and are greater than 15% different from sister species. This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and some paratypes (5 ♀; 3 ♂) deposited in the CNC; other paratypes (3 ♀; 3 ♂) deposited in the ACUA.

Diagnosis

Torrenticola reduncarostra are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba and T. shubini), Neoanomala Group (T. interiorensis and T. neoanomala), and T. bondi, T. gorti, T. elongata, T. erectirostra, T. robisoni, T. irapalpa, T. racupalpa, T. skvarlai, and T. arktonyx. T. reduncarostra can be differentiated from all Torrenticola, except Erectirostra Group, by having an upturned rostrum. T. reduncarostra can be differentiated from T. erectirostra, T. karambita, and T. robisoni by lacking dentation on the rostrum (others have strong dentation on the lateral edge of the rostrum).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola reduncarostra and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall appearance, small size, and elongate, ovoid body shape are consistent with placing this species in the Raptor Complex and within the Elongata Identification Group.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (1 ♀; 3 ♂) deposited in the CNC; other paratypes (1 ♀; 2 ♂) deposited in ACUA.

Diagnosis

Torrenticola regalis can be differentiated from all other western Torrenticola by having purple coloration covering the entire dorsal plate and by being the only member of the Miniforma Complex with indistinct or partial hind coxal margins. Occasionally its coloration can look similar to T. tahoei, but T. regalis can be differentiated from T. tahoei by having a shorter anterior venter (200–265 in T. regalis, 285–325 in T. tahoei), a stockier subcapitulum (ventral length/height = 2.41–2.68 in T. regalis, 3.25–4.11 in T. tahoei), and by having indistinct hind coxal margins (distinct in T. tahoei).

Remarks

Torrenticola regalis groups with other members of the Miniforma Complex with high support and is greater than 17% different from other species in the Ellipsoidalis Identification Group. This species is represented by a single specimen that does not resemble any other species group. This species hypothesis is supported by phylogenetic affinity, high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Torrenticola robisoni Fisher & Dowling, sp. n.

Material examined

HOLOTYPE (♀): from USA, Arkansas, Polk County, East Saline Creek, 30 Jul 2011, by IM Smith, IMS110041

PARATYPES (1 ♀; 0 ♂): Oklahoma, USA: Pushmataha County, beside Route 271, Walnut Creek (34°39'N 95°7'W), 1 Jul 1987, by IM Smith, IMS870063A

Type deposition

Holotype (♀) deposited in the CNC; paratype (1 ♀) deposited in the ACUA.

Diagnosis

Torrenticola robisoni are similar to other members of the Erectirostra Group (T. karambita and T. erectirostra). They are similar to other species with similar dorsal patterning, but can be differentiated from these by having a dentate, upturned rostrum that is wide when viewed ventrally. T. robisoni can be differentiated from T. erectirostra by having more elongate anterio-lateral platelets (length/width ♀ = 2.96–3.00 in T. robisoni, 2.52–2.69 in T. erectirostra). T. robisoni can be differentiated from T. karambita by having dorsal coloration (T. karambita is colorless) and having a more elongate rostrum (length/width ♀ = 2.09–2.09 in T. robisoni, 1.57–1.62 in T. karambita). T. robisoni can be further differentiated from T. erectirostra and T. karambita by being distributed in the Interior Highlands, while the others are in the Appalachians.

Etymology

Specific epithet (robisoni) named in honor of Henry W. Robison for his efforts in communicating the importance of the Interior Highlands (Ozarks and Ouachitas)—the type locality—which have a high proportion of endemic species, yet are understudied with respect to other areas of increased endemism (e.g., California floristic province, coastal plains, southern Appalachians, Pacific Northwest). His contributions instill passion for the region to even the casual reader, and have inspired many, including JRF, to pursue biodiversity research in the area.

Distribution

Known only from the Ouachita Mountains, possibly endemic (Figure 223).

Remarks

Torrenticola robisoni groups with other members of the Raptor Complex with high support. The single T. robisoni specimen that we were able to include in our phylogenetic analysis is 8–9% different in COI sequence from T. erectirostra and T. karambita. Based upon the distinctive morphology of the gnathosoma of these species, we place them in the Erectirostra Identification group.

This species hypothesis is supported by biogeography, high divergence between species, and by morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola rockyensis are similar to members of the Miniforma group (T. copipalpa, T. manni, T. miniforma, T. pacificensis, T. oliveri, and T. pinocchio) in having short, stocky pedipalps (except T. oliveri and T. pinocchio); similar pedipalpal extensions (unique to members of this group); and being among the smallest Torrenticola in the west (dorsum 500–625 long) (except T. oliveri). T. rockyensis can be differentiated from all other Miniforma group by being distributed in the Rocky Mountains. T. rockyensis are best differentiated from T. copipalpa by having tuberculate pedipalp femoral extensions (broad and flat in T. copipalpa). T. rockyensis are best differentiated from T. pacificensis by females having more elongate subcapitular rostra (length/width ♀ = 2.72–2.91 in T. rockyensis, 2.59–2.68 in T. pacificensis). T. rockyensis are best differentiated from T. manni by having stockier pedipalp tibiae (length/width = 2.47–3.11 in T. rockyensis, 3.13–3.38 in T. manni). T. rockyensis are best differentiated from T. miniforma by being larger (dorsum length ♀ = 570–620 in T. rockyensis, 545 in T. miniforma; ♂ = 525–545 in T. rockyensis, 485 in T. miniforma) and having stockier subcapitular rostra (length/width ♀ = 2.72–2.91 in T. rockyensis, 3.13 in T. miniforma; ♂ = 2.83–3.00 in T. rockyensis, 3.19 in T. miniforma). T. rockyensis can be differentiated by having a shorter anterior venter (175–223 in T. rockyensis, 250–310 in T. oliveri) and less elongate pedipalpal tibiae (length/width = 2.4–3.1 in T. rockyensis, 3.6–4.2 in T. oliveri). T. rockyensis can be differentiated from T. pinocchio by having a less elongate rostrum (length/width = 2.7–3.0 in T. rockyensis, 4.5–4.9 in T. pinocchio).

Etymology

Specific epithet (rockyensis) refers to the distribution of this species in the Rocky Mountains. This location-based naming reflects that locality is the easiest way to differentiate this species from others in the Miniforma Group, particularly T. pacificensis.

Distribution

Remarks

Torrenticola rockyensis groups with other members of the Miniforma group in all analyses with high support. All specimens are less than 1% different in COI sequence from each other and are greater than 5% different from other members of the group. This species is the only member of the Miniforma group that occurs in the Rocky Mountains.

This species hypothesis is supported by non-overlapping distributions, low COI divergence within the species, and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Torrenticola rockyensis groups with other members of the Miniforma Complex with high support and specimens of this species are less than 1% different in COI sequence from each other. In all analyses, T. rockyensis groups with three other morphologically similar species: T. pacificensis, T. manni, and T. copipalpa. Torrenticola rockyensis is greater than 5% different from the other three species in COI sequence and is the only one of the four to occur in the Rocky Mountains.

Based upon overall similarity, the pedipalp genu extensions, and western distribution, we were able to place this species in the Miniforma Identification Group.

This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola rufoalba are similar to other members of the Rusetria “4-Plates” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, and T. shubini) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. Male T. rufoalba can be differentiated from other male Rusetria four plates by having a shorter anterior venter (195 in T. rufoalba, 215–285 in others). T. rufoalba can be differentiated from T. dunni by having a shorter dorsum (♀ = 550 in T. rufoalba, 605–680 in T. dunni; ♂ = 440 in T. rufoalba, 500–540 in T. dunni) and a thinner dorsum (♀ = 400 in T. rufoalba, 440–490 in T. dunni; ♂ = 320 in T. rufoalba, 350–370 in T. dunni). T. rufoalba can be differentiated from T. pollani by having a stockier rostrum (length/width = 2.96–3.06 in T. rufoalba, 3.27–3.82 in T. pollani). Female T. rufoalba can be differentiated from female T. pollani by having stockier tibiae (length/width = 3.5 in T. rufoalba, 3.8–4.2 in T. pollani). T. rufoalba can be differentiated from T. shubini by having a more elongate rostrum (length/width = 2.96–3.06 in T. rufoalba, 2.24–2.92 in T. shubini). Female T. rufoalba can be differentiated from female T. shubini by having a wider genital field (157.5 in T. rufoalba, 137–145 in T. shubini). T. rufoalba can be differentiated from T. glomerabilis and by having more elongate anterio-medial platelets (length/width = 2.45–2.61 in T. rufoalba, 1.9–2.3 in T. glomerabilis) and thinner dorsum (♀ = 400 in T. rufoalba, 460–490 in T. glomerabilis; ♂ = 320 in T. rufoalba, 395–430 in T. glomerabilis). T. rufoalba can be differentiated from T. kittatinniana by having a shorter dorsum (♀ = 550 in T. rufoalba, 640 in T. kittatinniana; ♂ = 440 in T. rufoalba, 500 in T. kittatinniana) and stockier anterio-medial platelets (length/width = 2.45–2.61 in T. rufoalba, 2.83–2.88 in T. kittatinniana). T. rufoalba can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle.

Etymology

Habeeb (1955) did not specify an etymology for this specific epithet (rufoalba). However, we speculate that it refers to the dorsal coloration as Habeeb (1955) notes, “color red and white” (rufus, L. red; albus, L. white).

Remarks

Unfortunately, we were unable to acquire more specimens of Torrenticola rufoalba and therefore this species is not included in our phylogenetic analyses. However, we were able to examine the holotype. Based upon overall similarity, the fusion of the posterio-lateral platelets, and distribution, this species clearly groups with the Rusetria Complex and can be placed into the Eastern 2-Plate Identification Group.

Diagnosis

Torrenticola sellersorum are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. tysoni, T. ululata, T. whitneyae, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. It is one of only four Eastern 2-Plates that have dark, bold, bluish-purple coloration (also T. tysoni, T. biscutella, and T. pendula). T. sellersorum can be differentiated from T. ululata, T. indistincta, and T. feminellai by dorsal coloration and pattern. T. sellersorum can be differentiated from T. tysoni by having a stockier rostrum (length/width ♀ = 2.44–2.68 in T. sellersorum, 3.06–3.31 in T. tysoni; ♂ = 2.71–3.05 in T. sellersorum, 3.14–3.50 in T. tysoni). Female T. sellersorum can be differentiated from female T. biscutella by anterior venter/genital field length (0.69–0.77 in T. sellersorum, 0.82–0.88 in T. biscutella). Male T. sellersorum can be differentiated from male T. biscutella by having slightly more elongate anterio-lateral platelets (length/width = 2.76–3.00 in T. sellersorum, 2.58–2.74 in T. biscutella). T. sellersorum can be differentiated from T. pendula by having a stockier gnathosomal bay (length/width = 1.56–2.08 in T. sellersorum, 2.42–2.90 in T. pendula) and more elongate tibiae (length/width = 3.13–3.8 in T. sellersorum, 2.78–3.05 in T. pendula). T. sellersorum can be differentiated from T. whitneyae by having more elongate pedipalpal tibiae (length/width = 3.13–3.80 in T. sellersorum, 2.42–2.95 in T. whitneyae). T. sellersorum can be differentiated from T. microbiscutella by having a less elongate dorsum (length/width = 1.23–1.54 in T. sellersorum, 1.63–1.75 in T. microbiscutella). Female T. sellersorum can be differentiated from female T. malarkeyorum by anterior venter/genital field length (0.69–0.77 in T. sellersorum, 0.85–0.89 in T. malarkeyorum). Female T. sellersorum can be differentiated from female T. caerulea by having a wider genital field (150–182 in T. sellersorum, 120–145 in T. caerulea). Female T. sellersorum can be differentiated from female T. delicatexa by having a rounder dorsum (length/width = 1.23–1.37 in T. sellersorum, 1.38–1.44 in T. delicatexa). Male T. sellersorum do not have any measurement differences with male T. malarkeyorum, T. caerulea, and T. delicatexa; however, they can be differentiated by dorsal coloration.

Etymology

Specific epithet (sellersorum) named in honor of the grandparents of DMF, who always supported and encouraged her love of nature and discovery.

Distribution

Widespread (Figure 231). T. sellersorum are unlike all other Torrenticola in our collections in that they span either side of the Great Plains, which act as a barrier for most other species. T. sellersorum are likely absent from cool, highland streams of the Appalachians, Interior Highlands, and Rocky Mountains, but are likely widely distributed throughout the Interior. Explaining the peculiar distribution of T. sellersorum will depend on knowledge of dispersal capabilities, including host preference by the larvae and the dispersal capabilities of the host.

Remarks

In all analyses, Torrenticola sellersorum groups with other members of the Rusetria Complex with high support and specimens of this species are less than 2.3% different in COI sequence from each other. In all analysis, T. sellersorum groups with other eastern members of the Rusetria Complex that have fused lateral platelets. Because of this, we are able to place this species in the Eastern 2-Plate Identification Group.

The slightly increased COI variation of this species (2.3%) is expected for specimens separated by great geographic distance. For example, the specimens from Pennsylvania are 0–1.3% different from each other and the specimens from Saskatchewan are 0.3% different from each other, but Pennsylvania specimens are 1.3–2.0% different from the Saskatchewan specimens. However, even specimens from New Mexico are only 2.0–2.3% different from other localities, despite being separated by great geographic distance and ecoregions that act as barriers for other Torrenticola (i.e., the Great Plains). This variation in COI in the New Mexico samples supports two hypotheses: 1) given the relatively low divergence of approximately 2%, New Mexico specimens represent the same species as specimens further east; and conversely, 2) given the relatively high divergence of greater than 1%, New Mexico specimens represent a long-standing population, not a recent introduction from the east.

This species hypothesis is supported by low COI divergence within the species (0–2.3%) (but see above discussion) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola sharkeyi is unlike all other western species by having the following combination of characters: dorsal coloration, although faint, restricted posteriorly; indistinct hind coxal margins; and ellipsoid body. It is only known from Catron & Grant Counties, New Mexico. It is most similar to members of the Rala Group (T. rala, T. keesdavidsi, T. kurtvietsi, T. boettgeri, T. lamellipalpis, T. dolichodactyla, and T. anoplopalpa); however, members of this group are colorless. T. sharkeyi can be differentiated from T. boettgeri, T. kurtvietsi, T. lamellipalpis, T. keesdavidsi, and T. anoplopalpa by having tuberculate ventral extensions on the pedipalpal femora (others are lacking extensions, have dentate flanged extensions or wide lamellate extensions). T. sharkeyi can be differentiated from T. rala, T. kurtvietsi, T. boettgeri, T. dolichodactyla and T. anoplopalpa by having a more elongate pedipalpal tibiae (length/width = 3.81–4.10 in T. sharkeyi, 1.75–3.38 in others). T. sharkeyi can be differentiated from T. kurtvietsi, T. keesdavidsi, T. lamellipalpis, and T. anoplopalpa by having a stockier subcapitulum (ventral length/width = 2.03–2.40 in T. sharkeyi, 2.51–4.16 in others).

Remarks

Our analyses were unable to confidently place Torrenticola sharkeyi phylogenetically. The COI analyses recovers this species at the base of the Raptor Complex, but this relationship was not recovered in the combined analysis. Because of this ambiguity, we refrain from placing this species in a species complex. Furthermore, because of the unique morphology of this species, we refrain from placing this species in an identification group.

All specimens are less than 2% different in COI sequence from each other and greater than 16% different from sister species.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (greater than 3%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola shubini are similar to other members of the Rusetria “4-Plates” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, and T. rufoalba) and T. skvarlai in having anterio-lateral platelets free from the dorsal plate, dorsal coloration separated into anterior and posterior portions, and indistinct hind coxal margins. Female T. shubini can be differentiated from female T. dunni by having a thinner rostrum (length/width = 2.5–2.7 in T. shubini, 2.8–3.0 in T. dunni). Male T. dunni can be differentiated from male T. shubini by having a longer anterior venter (215–238 in T. shubini, 277–285 in T. dunni). T. shubini can be differentiated from T. pollani by having stockier tibiae (length/width ♀ = 3.30–3.60 in T. shubini, 3.89–4.18 in T. pollani; ♂ = 3.11–3.22 in T. shubini, 3.41–3.75 in T. pollani) and a stockier rostrum (length/width = 2.24–2.92 in T. shubini, 3.27–3.82 in T. pollani). T. shubini can be differentiated from T. glomerabilis by having the Dgl-4 closer to the dorsal edge (dorsal width/length between Dgl-4 = 1.2–1.4 in T. shubini; 1.5–1.7 in T. glomerabilis); and stockier tibiae (length/width ♀ = 3.3–3.6 in T. shubini, 4.1–4.5 in T. glomerabilis; ♂ = 3.1–3.2 in T. shubini, 3.5–4.4 in T. glomerabilis). Female T. shubini can be differentiated from female T. kittatinniana by having a stockier rostrum (length/width = 2.5–2.7 in T. shubini, 3.16 in T. kittatinniana) and a taller subcapitulum (140–145 in T. shubini, 125 in T. kittatinniana). Male T. shubini can be differentiated from male T. kittatinniana by having a shorter dorsum (400–465 in T. shubini, 500 in T. kittatinniana) and a shorter genital field (90–108 in T. shubini, 115 in T. kittatinniana). T. shubini can be differentiated from T. rufoalba by having a stockier rostrum (length/width = 2.24–2.92 in T. shubini, 2.96–3.06 in T. rufoalba). Female T. shubini can be differentiated from female T. rufoalba by having a thinner genital field (137–145 in T. shubini, 157.5 in T. rufoalba). Male T. shubini can be differentiated from male T. rufoalba by having a longer anterior venter (215–238 in T. pollani, 195 in T. rufoalba). T. shubini can be differentiated from T. skvarlai by having a conical pedipalpal femoral tubercle, whereas T. skvarlai has a broad and flat pedipalpal femoral tubercle, and by having a longer anterior venter (♀ = 156–170 in T. shubini, 140–153 in T. skvarlai; ♂ = 215–238 in T. shubini, 177–205 in T. skvarlai).

Etymology

Specific epithet (shubini) named in honor of author and palaeontologist Neil Shubin for his efforts to popularize stories of human evolution with his book (2009) and TV series (2014), Your Inner Fish. As with many of the species that Shubin studies (e.g., Tiktaalik roseae Daeschler, Shubin & Jenkins, 2006), Torrenticola shubini may represent a key evolutionary transition in the Rusetria Complex, between species that do and do not have their lateral platelets fused to the dorsal shield.

Remarks

Torrenticola shubini groups with other members of the Rusetria Complex with high support and specimens of this species are less than 2% different in COI sequence from each other. In all analyses, T. shubini groups with two other species with high support: T. dunni and T. pollani. Torrenticola shubini specimens are 5–12% different in COI sequence from these other species. The range of T. shubini overlaps with T. dunni in the southern Appalachians, but the ranges of these species do not overlap with T. pollani.

Based upon overall similarity, dorso-lateral platelet fusion, and distribution, we were able to place this species within the Eastern 4-Plate Identification Group

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola sierrensis are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. tricolor, T. trimaculata, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. sierrensis can be differentiated from most Tricolor Complex by being distributed in the west and having a wider genital field (♀ = 180–213 in T. sierrensis, 145–180 in others; ♂ = 135–175 in T. sierrensis, 92–120 in others), except for T. olliei (♀ = 190–203, ♂ = 130–138). T. sierrensis can be differentiated from T. olliei by having a more elongate rostrum (length/width = 1.95–2.14 in T. sierrensis, 1.56–1.81 in T. olliei).

Etymology

Although Marshall (1943) did not specify an etymology for the specific epithet (sierrensis), surely it refers to the type locality of this species within the Sierra Nevada in California.

Distribution

Western (Figure 240), but likely not found in the southwest. T. sierrensis was previously known only from a few localities in California; we extend the range in western North America, but not in the southwest.

Remarks

Torrenticola sierrensis group with other members of the Tricolor Complex with high support in all analyses and group with T. olliei to form the western portion of this complex. Specimens within this complex are 0–4.5% different in COI sequence from each other and greater than 6% different from T. olliei. This is higher sequence variability in COI than in most species hypotheses presented herein. However, given the topology in the COI tree (Figure 10) and morphological similarity, it seems apparent that the variability represents a continuum across a large distribution, rather than isolated species. This species hypothesis is supported by phylogenetic affinity and by the morphological characters outlined in the diagnosis.

Upon examining the types of T. sierrensis and T. mercedensis (Marshall, 1943), all characters for both species overlap with members of only one clade in our analyses. Therefore, it is apparent that these represent the same species hypothesis and must be synonymized. As First Revisers (ICZN Article 24.2), we select “sierrensis” as the senior synonym over “mercedensis” due to its broader range implication (“mercedensis” refers to the Merced River), even though T. sierrensis is distributed more widely than just the Sierra Nevada ranges.

Type deposition

Holotype (♀), allotype (♂), and other paratypes (12 ♀; 18 ♂) deposited in the CNC; other paratypes (5 ♀; 5 ♂) deposited in ACUA.

Diagnosis

Torrenticola skvarlai are similar to species with similar dorsal patterning, such as the Rusetria “4-Plate” group (T. dunni, T. glomerabilis, T. kittatinniana, T. pollani, T. rufoalba, and T. shubini), Elongata Group (T. elongata, T. gorti, and T. reduncarostra), Neoanomala Group (T. interiorensis and T. neoanomala), T. bondi, T. racupalpa, T. irapalpa, T. erectirostra, and T. arktonyx. They can be differentiated from all of these except Rusetria 4-Plates by having indistinct hind coxal margins. T. skvarlai can be differentiated from all Rusetria 4-Plates by having broadly tuberculate, dentate pedipalp femoral extensions (all Rusetria Complex have conical tuberculate pedipalp femoral extensions, usually without dentation) and by having a shorter anterior venter (♀ = 140–152.5 in T. skvarlai, 155–213 in Rusetria 4-Plates; ♂ = 177–205 in T. skvarlai, 215–285 in Rusetria 4-Plates).

Remarks

Torrenticola skvarlai groups with other members of the Raptor Complex with high support and specimens are less than 2% different in COI sequence from each other and greater than 9% from sister species. Placement of this species varied with analysis and was never well-supported. Furthermore, this species is not readily identifiable without keying, which does not warrant placement within an identification group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (2 ♀; 4 ♂) deposited in the CNC; other paratypes (2 ♀; 2 ♂) deposited in ACUA.

Diagnosis

Torrenticola solisorta are similar to other members of the Nigroalba Group (T. flangipalpa, T. nigroalba, and T. dentirostra) in being small, slightly elongate, having purple dorsal coloration restricted posteriorly, and having distinct yet poorly-defined hind coxal margins. T. solisorta can be differentiated from T. flangipalpa by having tuberculate pedipalp femoral extension (flange-like and anteriorly-directed in T. flangipalpa); a shorter anterior venter (192–225 in T. solisorta, 235–265 in T. flangipalpa); and more elongate pedipalp tibia (length/ width ♀ = 5.67–5.82 in T. solisorta, 4.79–5.00 in T. flangipalpa; ♂ = 5.08–5.17 in T. solisorta, 4.40–4.86 in T. flangipalpa). T. solisorta can be differentiated from T. dentirostra by having a smooth rostrum (T. dentirostra has a dentate bump midway on the dorsal edge of the rostrum) and more elongate pedipalpal tibiae (length/width ♀ = 5.6–5.9 in T. solisorta, 4.5–5.0 in T. dentirostra; ♂ = 5.0–5.2 in T. solisorta, 4.5–4.7 in T. dentirostra). T. solisorta can be differentiated from T. nigroalba by having orangish coloration immediately anterior to the purple dorsal coloration. Additionally, female T. solisorta can be differentiated from female T. nigroalba by having a slightly shorter dorsum (475–500 in T. solisorta, 500–530 in T. nigroalba); a thicker gnathosomal bay (length/width = 1.3–1.5 in T. solisorta, 1.25–1.55 in T. nigroalba); and a slightly thinner subcapitulum (3.14–3.30 in T. solisorta, 3.00–3.14 in T. nigroalba). Male T. solisorta also can be differentiated from T. nigroalba by anterior venter/medial suture (2.87–3.26 in T. solisorta, 2.54–2.77 in T. nigroalba) and having a wider dorsum (305–320 in T. solisorta, 290–300 in T. nigroalba). Other Torrenticola with purple dorsal coloration restricted posteriorly can be confused with T. solisorta, such as T. tahoei and T. oregonensis. Both of these species are larger (dorsum length ♀ = 475–500 in T. solisorta, 600–840 in others; ♂ = 425–460 in T. solisorta, 560–820 in others) and distributed in the west (T. solisorta is known only from the Ouachita Mountains in Arkansas).

Etymology

Specific epithet (solisorta) refers to the dorsal coloration of this species, which is the easiest way to differentiate it from its sister species (T. nigroalba). If one imagines the posterior purple color as the landscape and horizon, then the orangish coloration resembles the sun beginning to rise (solis ortus, L. sunrise).

Remarks

Torrenticola solisorta groups with other members of the Raptor Complex with high support in all analyses and specimens are less than 1% different in COI sequence from each other. In all analyses, T. solisorta groups with two other morphologically similar species: T. flangipalpa and T. nigroalba. Torrenticola solisorta is greater than 4% different in COI from its sister species (T. nigroalba). That clade of three species corresponds to an identification group, the Nigroalba Group, the members of which are easily differentiated by their size, coloration, long medial suture in females, and overall appearance.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola tahoei are similar to the other member of Tahoei group, T. oregonensis by subcapitulum shape, having purple coloration restricted posteriorly and being distributed in the west and to members of the Nigroalba Group (T. flangipalpa, T. nigroalba, T. solisorta, and T. dentirostra) in having purple dorsal coloration restricted posteriorly. T. tahoei can be differentiated from the Nigroalba Group by being larger (dorsum length ♀ = 600–720 in T. tahoei, 475–565 in Nigroalba Group; ♂ = 560–650 in T. tahoei, 425–510 in Nigroalba Group) and distributed in the west (Nigroalba Group are eastern). T. tahoei can be differentiated from T. oregonensis by being smaller (dorsum length ♀ = 600–720 in T. tahoei, 760–840 in T. oregonensis; ♂ = 560–650 in T. tahoei, 690–820 in T. oregonensis; dorsum width ♀ = 430–515 in T. tahoei, 560–640 in T. oregonensis; ♂ = 400–460 in T. tahoei, 520–605 in T. oregonensis) and a more elongate subcapitulum (ventral length/width = 3.25–4.11 in T. tahoei, 2.63–2.74 in T. oregonensis).

Etymology

Marshall (1943) did not specify an etymology for this specific epithet (tahoei).It surely refers to the collection locality of the paratype, Taylor’s Creek near Lake Tahoe, California, although the holotype was collected from Waddell Creek near the coast.

Distribution

Western, but not known from the southwest (Figure 249). T. tahoei was originally reported only from a few localities in California; we expand its known range into Oregon and Washington, and the Rocky Mountains.

Remarks

Torrenticola tahoei groups with members of the Miniforma Complex with high support in all analyses. There is considerable genetic variability within this species (0–3.8%), particularly between specimens from California and those from elsewhere. However, we find no morphological characters to support California specimens being recognized as a separate species, so we consider them all one widely distributed species.

This species is so distinct and recognizable from all other species that we do not place it within an identification group. It is greater than 11.6% different in COI sequence from other members of the Miniforma group.

This species hypothesis is supported by high divergence between species (3–15%) and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola tricolor are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. trimaculata, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. tricolor can be differentiated from all Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern. Although the spots always have this basic construction, there is great variability between specimens. T. tricolor are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. unimaculata, T. trimaculata, cardia, kringi, and T. mohawk). T. tricolor can be further differentiated from T. larvata by being rounder (dorsum length/width = 1.2–1.38 in T. tricolor, 1.41–1.57 in T. larvata) and stockier pedipalp tibiae (length/width ♀ = 3.0–3.11 in T. tricolor, 3.25–3.5 in T. larvata; ♂ = 2.7–2.8 in T. tricolor, 3.1–3.2 in T. larvata). T. tricolor can be further differentiated from T. trimaculata by having longer genital field (♀ = 187.5–210 in T. tricolor, 157.5–185 in T. trimaculata; ♂ = 145–170 in T. tricolor, 120–140 in T. trimaculata) and a slightly more elongate rostrum (length/width ♀ = 2.14–2.39 in T. tricolor, 1.91–2.1 in T. trimaculata; ♂ = 2.37–2.5 in T. tricolor, 2.05–2.22 in T. trimaculata). T. tricolor can be further differentiated from T. unimaculata by having stockier pedipalp tibiae (♀ = 3.0–3.11 in T. tricolor, 3.2–3.4 in T. unimaculata; ♂ = 2.69–2.8 in T. tricolor, 2.9–3.11 in T. unimaculata) and shorter medial suture in females (15–22.5 in T. tricolor, 40–47.5 in T. unimaculata). T. tricolor can be further differentiated from T. cardia by having a rounder dorsum (length/width = 1.2–1.38 in T. tricolor, 1.39–1.54 in T. cardia) and longer pedipalpal genua (75–83 in T. tricolor, 60–70 in T. cardia). T. tricolor can be further differentiated from T. kringi by having a stockier rostrum (length/width = 2.14–2.50 in T. tricolor, 2.67–3.13 in T. kringi). T. tricolor can be differentiated from T. mohawk by having a more elongate rostrum (length/width ♀ = 2.14–2.39 in T. tricolor, 1.80–2.00 in T. mohawk; ♂ = 2.37–2.50 in T. tricolor, 2.00–2.13 in T. mohawk).

Etymology

Although Habeeb (1957) did not specify an etymology for the specific epithet (tricolor), it surely refers to his comment on the dorsal coloration, “color black with some red and white” (tres, L. three; color, L. color).

Distribution

Northeastern and southward throughout the Appalachians (Figure 252). T. tricolor was previously known only from northern New Jersey.

Remarks

Torrenticola tricolor group with other members of the Tricolor Complex with high support and specimens of this species are less than 2.4% different in COI sequence from each other. This within-species sequence variability is higher than in many species hypotheses presented herein. However, given the topology in the COI tree (Figure 14) and morphological similarity, it seems apparent that the variability represents a continuum across a large distribution, rather than isolated species. In all analyses, T. tricolor group with two other species which also have dorsal spots: T. trimaculata and T. unimaculata. This clade represents some of the most distinctive of all Torrenticola. This species is greater than 7% different in COI from sister species.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola trimaculata are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. unimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. trimaculata can be differentiated from all Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern. Individuals are reported in two distinct morphs primarily based upon ventral coloration. T. trimaculata are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. unimaculata, T. tricolor, T. cardia, T. kringi, and T. mohawk). T. trimaculata can be further differentiated from T. larvata by being rounder (dorsum length/width = 1.2–1.37 in T. trimaculata, 1.41–1.57 in T. larvata); Dgl-4 closer to the muscle scars (dorsal width/distance between Dgl-4 = 1.49–1.69 in T. trimaculata, 1.18–1.35 in T. larvata); and a stockier rostrum (length/width = 1.91–2.22 in T. trimaculata, 2.32–2.53 in T. larvata). T. trimaculata can be further differentiated from T tricolor by having shorter genital field (♀ = 157.5–185 in T. trimaculata, 187.5–210 in T. tricolor; ♂ = 120–140 in T. trimaculata, 145–170 in T. tricolor) and a stockier rostrum (length/width ♀ = 1.91–2.1 in T. trimaculata, 2.14–2.39 in T. tricolor; ♂ = 2.05–2.22 in T. trimaculata, 2.37–2.5 in T. tricolor). T. trimaculata can be further differentiated from T. unimaculata by Dgl-4 closer to the muscles scars (dorsal width/distance between Dgl-4 = 1.49–1.69 in T. trimaculata, 1.23–1.41 in T. unimaculata) and females with shorter medial suture (♀ = 17.5–27.5 in T. trimaculata, 40–47.5 in T. unimaculata). T. trimaculata can be further differentiated from T. cardia by having Dgl-4 further from the edge of the dorsum (dorsum width/distance between Dgl-4 = 1.5–1.7 in T. trimaculata, 1.15–1.4 in T. cardia) and having a stockier rostrum (length/width ♀ = 1.191–2.10 in T. trimaculata, 2.24–2.50 in T. cardia; ♂ = 2.05–2.22 in T. trimaculata, 2.27–2.47 in T. cardia). T. trimaculata can be differentiated from T. kringi by having a stockier rostrum (length/width = 1.9–2.3 in T. trimaculata, 2.6–3.2 in T. kringi). T. trimaculata can be differentiated from T. mohawk by having a shorter anterior venter (♀ = 157–180 in T. trimaculata, 187–200 in T. mohawk, ♂ = 230–260 in T. trimaculata, 290–308 in T. mohawk). Additionally, female T. trimaculata can be differentiated from female T. mohawk by having longer pedipalpal tibiae (♀ = 90–97 in T. trimaculata, 77–88 in T. mohawk).

Etymology

Fisher et al. (2015) named the specific epithet (trimaculata) in reference to the dorsal coloration of three dark spots (tres, L. three; macula, L. spot).

Distribution

Remarks

Torrenticola trimaculata group with other members of the Tricolor Complex with high support in all analyses. All specimens of this species are less than 2% different in COI sequence from each other and are greater than 7% from sister species. In all analyses, T. trimaculata groups with two other species which also have dorsal spots: T. tricolor and T. unimaculata. This clade represents some of the most distinctive of all Torrenticola.

This species hypothesis is supported by low COI divergence within the species (0–2%), high divergence between species (3–15%), and the morphological characters outlined in the diagnosis.

Fisher et al. (2015) reported two color morphs based primarily upon presence of ventral coloration. Morph I, with a dark venter, was only known from the Interior Highlands and all eastern specimens were reported as Morph II, with a colorless venter. However, we examined additional specimens from across eastern North America and found colored individuals mixed within samples of uncolored individuals. We remain unsure what controls color in Torrenticola, but with several other species exhibiting great color variation (e.g., T. tricolor, T. gorti), we do not consider it useful to continue with the “morph” concept in this species.

Diagnosis

Torrenticola tysoni are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. sellersorum, T. ululata, T. whitneyae, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. It is one of only four Eastern 2-Plates that have dark, bold, bluish-purple coloration (also T. biscutella, T. sellersorum, and T. pendula). T. tysoni can be further differentiated from other Eastern 2-Plates by having a more elongate rostrum (length/width = ♀ = 3.06–3.31 in T. tysoni, 2.33–3.0 in others; ♂ = 3.14–3.50 in T. tysoni, 2.50–3.05 in others), except T. feminellai (3.05–3.38) and female T. pendula (3.0–3.06). T. tysoni can be differentiated from T. feminellai and T. pendula by dorsal coloration and pattern.

Etymology

Specific epithet (tysoni) named in honor of Neil Degrasse Tyson for his efforts in popularizing cosmology and science in general with Cosmos: A Spacetime Odyssey (2014), which was a worthy update to Carl Sagan’s Cosmos: A Personal Voyage (1980).

Distribution

Known only from several localities along Natchez Trace Parkway (Figure 258).

Remarks

Torrenticola tysoni groups with other members of the Rusetria Complex with high support. Specimens of this species from Tennessee and Alabama are less than 1% different in COI sequence from each other and the specimen from Arkansas is less than 2% different from those. This species is greater than 10% different from sister species.

In all analyses, T. tysoni groups with two other species (T. sellersorum and T. pendula) as a paraphyletic grade at the base of the Eastern 2-Plate Identification Group. Based upon overall similarity, lateral platelets fused with the dorsal shield, and distribution, we were able to place this species within the Eastern 2-Plate Identification Group.

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (1 ♀; 2 ♂) deposited in the CNC; other paratypes (1 ♀; 1 ♂) deposited in ACUA.

Diagnosis

Torrenticola ululata are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. sellersorum, T. tysoni, T. whitneyae, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, and being distributed in the east. T. ululata can be differentiated from most Torrenticola, including other Eastern 2-Plates, by having a distinct dorsal pattern with a single dark spot posteriorly and an orange spot posterior to the dark spot. The only other species with this pattern is T. unimaculata and T. kringi, which both have anterio-lateral platelets free from the dorsal plate.

Type deposition

Holotype (♀), allotype (♂), and most paratypes (4 ♀; 3 ♂) deposited in the CNC; other paratypes (3 ♀; 3 ♂) deposited in ACUA.

Diagnosis

Torrenticola unimaculata are similar to other members of the Tricolor Complex (T. bittikoferae, T. hoosieri, T. larvata, T. pearsoni, T. olliei, T. sierrensis, T. tricolor, T. trimaculata, T. cardia, T. kringi, T. dimorpha, and T. mohawk) in having a short, conical rostrum. T. unimaculata can be differentiated from most Torrenticola, including other members of the Tricolor Complex, by having a distinct dorsal pattern of a large anterior dorsal spot. The only other species with this pattern is T. ululata, which, like all Rusetria 2-Plates, have anterio-lateral platelets fused to the dorsal plate and T. kringi, which has a more elongate rostrum (length/width = 1.9–2.2 in T. unimaculata, 2.6–3.2 in T. kringi). T. unimaculata are most similar to other members of the Tricolor Complex that have bold patterning (T. larvata, T. tricolor, T. trimaculata, T. cardia, T. kringi, and T. mohawk). Female T. unimaculata can be further differentiated from these members of the complex by having a longer medial suture (♀ = 40–47.5 in T. unimaculata, 15–35 in others), except T. cardia (25–50) and T. mohawk (30–45).

Remarks

Torrenticola unimaculata groups with other members of the Tricolor Complex with high support and specimens of this species are less than 2% different in COI sequence from each other. In all analyses, T. unimaculata groups with two other species which also have dorsal spots: T. trimaculata and T. tricolor. This clade represents some of the most distinctive of all Torrenticola. This species is greater than 7% different in COI from sister species.

This species hypothesis is supported by high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola ventura is unlike all other western species by having the following combination of characters: anterio-lateral platelets free (fused to dorsal plate in Rusetria Complex); dorsal coloration separated into anterior and posterior portions (restricted posteriorly in T. tahoei, T. oregonensis, T. raptoroides, and T. sharkeyi, without pattern in T. regalis, colorless in T. occidentalis, Rala Group, T. wiedenmanni); ellipsoid body (circular in T. sierrensis and T. raptoroides, rectangular in T. ellipsoidalis); unmodified rostrum (short and conical in T. olliei, T. sierrensis, T. ellipsoidalis and T. leviathan); tuberculate ventral extensions on pedipalp genua (flanged in Miniforma group); and smaller body size than T. multiforma (dorsum length ♀ = 650–780 in T. ventura, 765–885 in T. multiforma; ♂ = 540–630 in T. ventura, 725–850 in T. multiforma). T. ventura are most similar to members of the Neoanomala Group, which are eastern.

Etymology

Although Habeeb (1973) did not specify an etymology for the specific epithet (ventura), it surely refers to the type locality—Ventura River in Ventura County, California.

Distribution

California and southwest Oregon (Figure 267). T. ventura was previously known only from Ventura County in southwestern California; we extend the range northward.

Remarks

Our analyses were unable to confidently place Torrenticola ventura phylogenetically. Both analyses place this species at the base of the Raptor Complex, but this relationship was not well-supported. Because of this ambiguity, we refrain from placing this species in a species complex. Furthermore, because of the unique morphology, we are also unable to place this species within an identification group.

All specimens are less than 1% different in COI sequence and are greater than 15% different from sister species. This species hypothesis is supported by biogeography, low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola walteri are similar to other members of the Rusetria “Western 2-Plates” group (T. mulleni, T. nortoni, and T. welbourni) in having anterio-lateral platelets fused to the dorsal plate, having faint dorsal coloration, and being distributed in the west. Female T. walteri can be differentiated from T. welbourni (female only known) by having stockier pedipalp tibiae (3.09–3.23 in A32, 3.73 in A30); shorter pedipalp femora (112.5–125 in A32, 137.5 in A30); and a more elongate subcapitulum (ventral length/height: 2.21–2.34 in A32, 2.47 in A30). T. walteri can be differentiated from T. mulleni by having a slightly stockier gnathosomal bay (♀ = 1.57–1.84 in T. walteri, 1.89–2.16 in T. mulleni, ♂ = 1.55–1.73 in T. walteri, 1.77–1.93 in T. mulleni) and by being distributed in California, Oregon and British Columbia, instead of in the Rocky Mountains (Idaho, Montana, Utah and Wyoming). Additionally, male T. walteri can be differentiated from male T. mulleni by having a shorter genital field (115–117.5 in A32, 130–140 in A31), and female T. walteri can be differentiated from female T. mulleni by having a shorter medial suture (10–12.5 in T. walteri, 20—22.5 in T. mulleni). Female T. walteri can be differentiated from female T. nortoni by having slightly shorter pedipalp femora with respect to genua (1.52–1.64 in T. walteri, 1.69–1.82 in T. nortoni) and slightly stockier anterio-medial platelets (2.58–2.72 in T. walteri, 2.74–3.06 in T. nortoni). Male T. walteri can be differentiated from male T. nortoni by having longer pedipalp femora (95–100 in T. walteri, 85–92.5 in T. nortoni) and slightly more elongate pedipalp tibiae (3.05–3.10 in T. walteri, 2.73–3.0 in T. nortoni).

Etymology

Specific epithet (walteri) named in honor of acarologist Dave Walter for solidifying JRF’s interest in mites with his popular book on mites (Mites: Ecology, Evolution & Behaviour – Life at a Microscale) and by teaching JRF the mesostigmatan mite section of the Acarology Summer Program at The Ohio State University in 2009.

Distribution

Probably throughout the Pacific Coastal Ranges of California, Oregon, Washington, and southern British Columbia (Figure 270). We also collected T. walteri in the Rocky Mountains of British Columbia, indicating this species might occur in the northern Rockies of Canada. However, given our sampling effort in the Rockies, we doubt the occurrence of this species in most of the US Rockies.

Remarks

Torrenticola walteri groups with other members of the Rusetria Complex with high support and specimens are less than 2% different in COI sequence from each other. In the all analyses, T. walteri groups with the three other members of the Rusetria Complex that are found in western North America: T. mulleni, T. nortoni, and T. welbourni. These species are 5–7% different in COI sequence from each other and together make up the Western 2-Plate Identification Group. Torrenticola walteri is one of three of these that occur in California (including T. nortoni and T. welbourni).

This species hypothesis is supported by low COI divergence within the species (0–2%) and high divergence between species (3–15%), and by the morphological characters outlined in the diagnosis.

Diagnosis

Torrenticola welbourni are similar to other members of the Rusetria “Western 2-Plates” group (T. mulleni, T. nortoni, and T. walteri) in having anterio-lateral platelets fused to the dorsal plate, having faint dorsal coloration, and being distributed in the west. T. welbourni (only female known) can be differentiated from all other Western 2-plates by being larger (dorsal length: 690 in T. welbourni, 570–645 in others; dorsal width: 500 in T. welbourni, 415–480 in others), having more elongate pedipalp tibiae (length/width: 3.73 in T. welbourni, 3.0–3.33 in others) and longer pedipalp femora (137.5 in A30, 112.5–125 in others).

Etymology

Specific epithet (welbourni) named in honor of acarologist Cal Welbourn, who has been instrumental in teaching terrestrial Parasitengona to JRF and for teaching JRF the prostigmatan mite section of the Acarology Summer Program at The Ohio State University in 2009.

Distribution

Remarks

Torrenticola welbourni groups with other members of the Rusetria Complex with high support. Unfortunately, only a single specimen is known of this species, so variation in COI sequence could not be investigated. This specimen was collected from the sample that contained specimens of T. walteri. It is interesting to note that these two species are the only Rusetria Complex members collected from Trinity County. In the all analyses, T. welbourni groups with the three other members of the Rusetria Complex that are found in western North America: T. mulleni, T. nortoni, and T. walteri. These species are 5–7% different in COI sequence from each other and together make up the Western 2-Plate Identification Group. Torrenticola welbourni is one of three of these that occur in California (including T. nortoni and T. walteri).

Type deposition

Holotype (♀), allotype (♂), and some paratypes (2 ♀; 1 ♂) deposited in the CNC; other paratypes (2 ♀; 1 ♂) deposited in the ACUA.

Diagnosis

Torrenticola whitneyae are similar to other members of the Rusetria “Eastern 2-Plates” group (T. biscutella, T. caerulea, T. delicatexa, T. indistincta, T. malarkeyorum, T. pendula, T. sellersorum, T. tysoni, T. ululata, T. microbiscutella, and T. feminellai) in having anterio-lateral platelets fused to the dorsal plate, having dorsal coloration separated into anterior and posterior portions (except T. ululata and T. indistincta), and being distributed in the east. T. whitneyae is most similar to T. pendula, which also has purple coloration separated into anterior and posterior portions and often connected by a stripe medially. T. whitneyae is best differentiated from T. pendula by having a stockier rostrum (length/width = 2.41–2.69 in T. whitneyae, 2.87–3.06 in T. pendula). T. whitneyae can be differentiated from T. ululata, T. indistincta, and T. feminellai by dorsal coloration and pattern. T. whitneyae can be differentiated from all other Eastern 2-Plates by having stockier pedipalpal tibiae (♀ = 2.42–2.95 in T. whitneyae, 3.00–4.59 in others; ♂ = 2.48–2.70 in T. whitneyae, 2.78–4.25 in others), except female T. delicatexa (♀ = 2.92–3.61). T. whitneyae can be differentiated from T. delicatexa by having a slightly rounder dorsum (length/width ♀ = 1.26–1.38 in T. whitneyae, 1.38–1.44 in T. delicatexa; ♂ = 1.35–1.37 in T. whitneyae, 1.44–1.56 in T. delicatexa) and by dorsal coloration.

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola whitneyae and therefore this species is not included in our phylogenetic analyses. However, we were able to examine morphology with material preserved in GAW. The overall similarity, distribution in the east, and fusion of the dorso-lateral platelets to the dorsal plate, are consistent with placing this species in the Rusetria Complex and within the Eastern 2-Plate Identification Group.

Etymology

Specific epithet (wiedenmanni) named in honor of Rob Wiedenmann, Professor of Entomology at University of Arkansas, whose advice, guidance, and friendship to JRF was an inspiration in how to be a true mentor—lessons that JRF anticipates paying forward to his own students someday.

Distribution

Southern California (Figure 278).

Remarks

Unfortunately, we were unable to acquire fresh material of Torrenticola wiedenmanni and therefore this species is not included in our phylogenetic analyses, but we were able to examine morphology with material preserved in GAW. However, due to its unique set of characteristics, we are unable to place this species into a species complex or an identification group.

Key to Torrenticola of the United States and Canada

Species Groups are placed within key to aid identification. However, not all groups are included and some appear multiple times (Ellipsoidalis Group; male members of the Elongata, Rala, Raptor, and Tricolor Groups).
