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.

Torrenticolidae Piersig, 1902 are known as “torrent mites” due to the typical habitat of most species—fast-flowing, rocky or sandy-bottom streams (

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
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
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.

To increase time-efficiency,
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
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 (
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.,
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 (
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
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.

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.

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.

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.

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.
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.

Tricolor Complex (Figure
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
Tricolor Complex (part II). Most species of the Tricolor Complex are eastern, but one lineage is western: T. sierrensis, widespread; and T. olliei, north Pacific coast. The most apomorphic Torrrenticola (T. dimorpha) is recovered here in all analyses. Note that three species (T. pearsoni, T. hoosieri, and T. projector) are repeated in Figure
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
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;
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
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
“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) (
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.,
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).

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).

Specific epithet (anoplopalpa) refers to the pedipalps, which lack tubercles on the femora and genua, an uncommon condition in Torrenticola, which usually have tuberculate ventral extensions (anoplos, G. unarmed; palpus, L. hand, feeler).
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. The overall appearance, incomplete hind coxal margins, lack of coloration, and distribution, are consistent with placing this species in the Rala Identification Group.

Unfortunately, we were unable to acquire fresh material of Torrenticola arktonyx and therefore this species is not included in our phylogenetic analyses. We were able to examine material preserved in GAW for morphology, but due its unique characteristics, we are unable to place this species into either a species complex or identification group. However, based upon coloration, distribution, and gnathosomal shape, we speculate that future analyses will place this species in the Raptor Complex.

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).

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.

bittikoferae
:
PARATYPES (0 ♀; 2 ♂): Ohio, USA: 2 ♂ from Ottawa County, Middle Bass Island, rubble beach, 29 June 1954, by R Crowell.
Holotype (♀) and some paratypes (unspecified number) deposited in the Chicago Natural History Museum (unexamined; types not located); other paratypes (2 ♂) deposited in the OSUAC.
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).

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

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.

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

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.

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.

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

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.

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).

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.
Northern California and western Oregon (Figure
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.

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

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).

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.

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).

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.

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.

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.

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.

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

Specific epithet (dolichodactyla) refers to elongate pedipalp tarsus (dolichos, G. long; daktylos, G. finger), which is the most elongate of all Torrenticolidae.
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.

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).
Southeastern Appalachians (Figure
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.

Holotype (♀) and paratype (1 ♀) deposited in the
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).

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).

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

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).

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.
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.

Specific epithet (erectirostra) refers to the upturned rostrum characteristic of members of the Erectirostra Group (erectus, raised up; rostrum, L. snout).
Appalachians (Figure
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.

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.

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.

Holotype (♀), allotype (♂), and most paratypes (3 ♀; 4 ♂) deposited in the
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). Other Torrenticola with purple dorsal coloration restricted posteriorly, such as T. tahoei and T. oregonensis are larger (dorsum length ♀ = 530–565 in T. flangipalpa, 600–810 in others; ♂ = 480–510 in T. flangipalpa, 560–820 in others) and distributed in the west (T. flangipalpa is only known from Alabama and Tennessee).

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.
Southeastern (Figure
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.

Specific epithet (glomerabilis) refers to the rounded body of this species compared to all other members of the Rusetria Complex (glomerabilis, L. round).
Appalachians (Figure
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
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.

Holotype (♀), allotype (♂), and most paratypes (19 ♀; 16 ♂) deposited in the
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).

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.

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.

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.

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).

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

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).

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.

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

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).

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.

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

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.

Unfortunately, we were unable to acquire fresh material of Torrenticola kurtvietsi 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 Mexico. Based upon overall similarity, incomplete hind coxal margins, distribution, and lack of coloration, this species fits within our concept of the Rala Identification Group.

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.

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.

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.

Specific epithet (longitibia) refers to the long, thin pedipalpal tibiae (longus, L. long; tibia, L. tibia).
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.

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
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.

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.

Eastern (Figure
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.

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.

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.

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.

Specific epithet (mjolniri) named after Mjölnir—the hammer of Thor in Norse mythology—the ancient symbol of which resembles the dorsal patterning this species.
Northeastern (Figure
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.

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.

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.

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.

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.
Rocky Mountain region (Figure
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.
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.

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).

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).

T. neoanomala was previously known only from Albert County, New Brunswick, but we extend its range throughout eastern North America (Figure
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.

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).

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.

Holotype (♀), allotype (♂), and some paratypes (5 ♀; 2 ♂) deposited in the
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).
Female (Figure

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.
California (Figure
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.

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).

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).

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.

Specific epithet (oregonensis) refers to the distribution of this species, which was paradoxically found in several ecoregions across Oregon, but not in surrounding areas.
Oregon (Figure
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.

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

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.
Western Oregon and western Washington (Figure
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.

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).

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.

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).

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.

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.

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.

Southeastern (northern Alabama and Georgia) (Figure
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.

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.

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.

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.

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).

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.

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

This is higher sequence variability than in many species hypotheses presented herein. However, given the topology in the COI tree (Figure
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.

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.

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.

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).

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.

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.
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.

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.

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.

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.

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.

Widespread (Figure
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.

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).

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.

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).

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.
Appalachians (Figure
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.

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).

Although
Western (Figure
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
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.

Specific epithet (skvarlai) named in honor of Michael Skvarla, who collected specimens of the species and is a dear friend and colleague of JRF.
Appalachians (Figure
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.

PARATYPES (4 ♀; 6 ♂): Arkansas, USA: 2 ♂ from Montgomery County, Gaston, South Fork Ouachita River, 29 Jul 2011, by IM Smith, IMS110040 • 1 ♂ (ALLOTYPE) from Montgomery County, Ouachita National Forest, South Fork Ouachita River, 29 Jul 2011, by AJ Radwell, & B Crump, AJR110302 • 4 ♀ and 3 ♂ from Polk County, East Saline Creek, beside Forest Road 38, north of Shady Lake Recreation Area, 30 Jul 2011, by IM Smith, IMS 110041.
Holotype (♀), allotype (♂), and most paratypes (2 ♀; 4 ♂) deposited in the
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).

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).
Ouachita Mountains (Figure
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.

Holotype (♀) and allotype (♂) deposited in the
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).

Western, but not known from the southwest (Figure
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.

Holotype (♀) and allotype (♂) deposited in the
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).

Holotype (♀), allotype (♂), and other paratypes (44 ♀; 32 ♂) deposited in the
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 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).

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.

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

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.

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).

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.

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.
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).

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.

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.
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).
