Abstract

This study documents a comprehensive taxonomic treatment of the New World Ummidia species. At the onset of this work the genus comprised 27 species and one subspecies with a cosmopolitan distribution that includes North America, South America, Asia, northern Africa, and Europe; of these species the majority of the nominal diversity can be attributed to the New World where 20 species have been previously described. Ummidia oaxacana (Chamberlin, 1925) is considered a nomen dubium; U. tuobita (Chamberlin, 1917) and U. absoluta (Gertsch and Mulaik, 1940) are both considered junior synonyms of U. audouini (Lucas, 1835); the subspecies U. carabivora emarginata (Atkinson, 1886) is considered a junior synonym of U. carabivora (Atkinson, 1886); U. pygmaea (Chamberlin and Ivie, 1945) is considered a junior synonym of U. beatula (Gertsch and Mulaik, 1940); U. celsa (Gertsch and Mulaik, 1940) is considered a junior synonym of U. funerea (Gertsch, 1936); Hebestatis lanthanus (Valerio, 1987) is considered a junior synonym of U. rugosa (Karsch, 1880). Thirty-three new species are described: U. neilgaimani, U. gingoteague, U. rongodwini, U. okefenokee, U. richmond, U. macarthuri, U. colemanae, U. rosillos, U. mercedesburnsae, U. paulacushingae, U. waunekaae, U. gertschi, U. timcotai, U. gabrieli, U. pesiou, U. rodeo, U. huascazaloya, U. anaya, U. cuicatec, U. brandicarlileae, U. riverai, U. frankellerae, U. hondurena, U. yojoa, U. matagalpa, U. carlosviquezi, U. varablanca, U. quepoa, U. cerrohoya, U. quijichacaca, U. tibacuy, U. neblina, U. tunapuna.

Introduction

The trapdoor spider genus Ummidia (Mygalomorphae: Halonoproctidae) has long been recognized as being in serious need of taxonomic treatment. At the beginning of this study, Ummidia contained 27 nominal species, 20 of which are found in the New World. Ummidia asperula (Simon, 1889) and U. glabra (Doleschall in Ausserer, 1871) are found in Venezuela and Brazil, respectively. Ummidia salebrosa (Simon, 1891b) is described from St. Vincent, and U. nidulans (Fabricius, 1787) from the West Indies. Six species are described from Mexico and Central America: U. erema (Chamberlin, 1925), U. oaxacana (Chamberlin, 1925), U. pustulosa (Becker, 1879), U. rugosa (Karsch, 1880), U. zebrina (Pickard-Cambridge, 1897), and U. zilchi (Kraus, 1955). In the United States there are ten nominal species, U. absoluta (Gertsch and Mulaik, 1940), U. audouini (Lucas, 1835), U. beatula (Gertsch and Mulaik, 1940), U. carabivora (Atkinson, 1886), U. carabivora emarginata (Atkinson, 1886), U. celsa (Gertsch and Mulaik, 1940), U. funerea (Gertsch, 1936), U. modesta (Banks, 1901), U. pygmaea (Chamberlin and Ivie, 1945), and U. tuobita (Chamberlin, 1917), which range from as far north as Maryland and Ohio, south to Florida and to Arizona in the west. Unfortunately, the descriptions for these species (Ausserer 1875, Atkinson 1886, Gertsch and Mulaik 1940) are either vague or utilize characters that are not necessarily useful in species diagnosis. In short, taxonomic work on New World Ummidia has been sparse aside from these original descriptions, the most recent of which are over half a century old. Despite these shortcomings the genus has long captured the imaginations of spider taxonomists due to its putative remarkable diversity, recognized as potentially containing as many as 50 undescribed North American species (Hendrixson and Bond 2005).

Since Raven’s (1985) revision of all mygalomorph spider genera, the taxonomic composition of the family Ctenizidae and consequent placement of Ummidia has remained problematic, particularly with the application of molecular approaches to resolving relationships (Hedin and Bond 2006, Bond et al. 2012). Historically a member of the Ctenizidae until genomic data revealed that the family (sensu lato) comprised genera belonging to three different independent lineages (Godwin et al. 2018), Ummidia is now placed within the family Halonoproctidae (Pocock, 1901), subfamily Ummidiinae (Ortiz, 2007) which also contains Latouchia (Pocock, 1901) and Conothele (Thorell, 1878). Likewise, whether or not Ummidia and Conothele constitute independent genera has been the subject of long-standing debate (Main 1998, Decae 2010, Opatova et al. 2013). The genera are morphologically similar but found in different regions, with Ummidia occurring in Central Asia, the Mediterranean, and Americas and Conothele in Australia and southeast Asia. Given their apparent morphological similarity Decae (2010) and Main (1998) concluded that the genera should be synonymized, but phylogenetic analyses using hundreds of loci and extensive sampling of both genera from across their ranges showed conclusively that the genera form two independent evolutionary lineages (Godwin et al. 2018). A more recent study which placed these genera in the context of all Mygalomorphae estimated the divergence time of the two lineages at just over 50 mya which is comparable to generic level divergences for other mygalomorph taxa (Opatova et al. 2020). A second relatively recent phylogenetic study by Opatova et al. (2013) also shows that the North American Ummidia species form a monophyletic group exclusive of the Old World taxa.

Ummidia are medium-sized trapdoor spiders that construct silk-lined burrows, usually with cork-type doors (Bond and Coyle 1995). These burrows are cryptic and difficult to find and are often covered in leaf litter (Gertsch and Wallace 1936, Coyle 1981, Bond and Coyle 1995). Ballooning, a behavior that distinguishes some Ummidia from most other mygalomorphs, has been observed in a few species. A peculiar behavior among most mygalomorphs, it was first noted to occur in Ummidia by Baerg (1928) but observed again by Coyle (1985), Coyle et al. (1985), Eberhard (2006), and Fisher et al. (2014). This behavior is significant for biogeographical studies, as Ummidia species have been found on multiple islands in the Caribbean, including the volcanic island of St. Vincent (Simon 1891b) and possibly Bermuda (Whitehead unpublished), 1000 km off the eastern coast of the US. The observation of ballooning by Ummidia is especially interesting because it facilitates the dispersal of individuals over geographic features that would otherwise serve as barriers to gene flow. Increased gene flow due to long-distance dispersal via ballooning by Ummidia species represents a significant departure from what is known for other studied mygalomorph taxa; that is, trapdoor spiders are considered to have extreme population structuring and are considered to be non-vagile (Bond et al. 2001, 2006, Hendrixson and Bond 2005, Arnedo and Ferrández 2007, Starrett and Hedin 2007, Bond and Stockman 2008, Satler et al. 2011).

We present here the first species level revision of Ummidia from the Nearctic region wherein we provide updated descriptions for all described species and describe 33 new species. Although species of Ummidia are very widespread and occur in a number of habitats (Map 1, Fig. 1), they tend to be very patchy in their distribution. This, paired with the highly cryptic nature of their burrows, make them very difficult to collect, and so by necessity this revision is based almost entirely on historic rather than newly collected material. Much of this material was amassed from a number of collectors and institutions by the late Dr. Willis Gertsch, who spent over 40 years working on a revision of the group. Gertsch never published his work on Ummidia prior to his passing in 1999, but his notes and correspondence, stored in the archives of the American Museum of Natural History proved useful and insightful in the completion of this work. A quote, taken from these correspondences, is possibly the best expression of the difficulty of revising this morphologically homogenous group, “this is the most difficult ctenizid genus I know with such feeble, variable, erratic, aberrant characters that I find myself uncertain as to...what is a species.” With the material available to us, we have done our best to accurately delimit species but openly acknowledge that this work represents a first attempt and that much work remains on this enigmatic, geographically widespread, and notoriously difficult genus of trapdoor spiders.

Measurement, characterization, and illustration of morphological features

Approximately 800 specimens of Ummidia from various collections (AMNH, BME, CMC, DMNS, MCZ, MEM, MNHN, MSU, NUCMHN, OSU, SMF, TAMU, UFMNH, NHMUK, CNAN, VMNH) have been examined. Each specimen has been given a unique voucher number deposited in each vial. Specimens were measured using a Leica M165C equipped with Leica Analysis Suite Software, and all measurements are given in millimeters. Measurements of leg article lengths were taken from the mid-proximal point of articulation to the mid-distal point of the article in accordance with Bond 2012 (Figs 1116). Carapace, leg, and abdomen coloration are described semi-quantitatively using Munsell® Color Charts (Windsor, NY) and are given using the color name and color notation (hue value/chroma).

We evaluated the morphological variation among species using principle components analysis. Base R (R Core Team 2014) scripts and the package “ggplot2” (Wickham 2016) were used. All measurements were log transformed to account for differences in body size, and morphospace was evaluated by plotting PC1 against PC2. PCAs were run on males and females separately further divided by geographic region. Specimens from the South America and Caribbean region were not included due to insufficient sampling.

For representative male specimens, photographs were taken of the retrolateral aspect of the palp and the retro- and prolateral aspects of the mating clasper. The genital region was removed from the abdominal wall and tissues dissolved by incubating in trypsin overnight for representative females. Spermathecae were then examined, measured, and photographed. All specimens were photographed using a Visionary Digital Imaging System (Visionary DigitalTM, Richmond, VA), which recorded images in multiple focal planes. The images were then assembled into a single focused image using Helicon Focus software (Helicon Soft, Ltd. Ukraine). Line drawings of male mating claspers and palpal tibiae were created using these digital images, which were traced as vector line drawings using Adobe Illustrator (Adobe Systems Inc.). Habitus illustrations were created both for described and undescribed species in order to create digitized records of the type material. Type specimens were photographed in the same manner as other structures and then modified in Adobe Illustrator (Adobe Systems Inc.) to create symmetrical morphological illustrations of type specimens. However, given the poor condition of many of the historical specimens, in some cases fully symmetrical illustrations were not possible.

Locality data, georeferencing

The locality data from these specimens were databased and georeferenced by hand using Google Earth (WGS84 datum). Due to the vague nature of many older locality labels on museum material, some localities are imprecise. In cases where only a town or county is given as a locality, the specimens were georeferenced to the geographic center of the given locality. Therefore, latitude and longitude were recorded to the fourth decimal place not as an indication of the precision of the recorded locality or the exact location, but as an indication of the precision of the point assigned during georeferencing. A precision ranking for each georeferenced point was given as a superscript in the material examined section. The rankings are as follows: 1 = exact coordinates given, 2 = amended exact coordinates (i.e., exact coordinates given but were emended on validation), 3 = public land survey system (or herein geographic place name), 4 = within 1 km radius, 5 = within 5 km radius, 6 = within 10 km radius, 7 = to county or > 10 km, 8 = to state, and 9 = to project region (Murphy et al. 2004). Species distribution maps were then generated in ArcGIS using either given or assigned points.

Designation of types and species groups

Given their conserved morphology and sexual dimorphism, matching males to females within a species without the aid of molecular data can be quite challenging. In this revision we have opted for a conservative approach in designating holotypes and paratypes. For new species being described from both sexes, the male is designated as holotype as males tend to possess more diagnostic characters than females. If the female specimen is either from the same locality as the holotype or relatively nearby, it is designated as a paratype. For new species where males and females are available, but not collected in geographic close proximity, the female specimen is described as an exemplar. For described species museum types were examined. These specimens were photographed and measured in the same manner as those examined for new species and new descriptions and diagnoses were written. We have done this in the hope of making these specimen data and digitized images available for future study of these old and valuable specimens. Locality data for type specimens is provided in Table 1 and displayed in Map 1.

For pragmatic purposes, we have divided the genus into four species groups: the eastern United States (Maps 2, 3), western United States and northern Mexico (Map 4), southern Mexico and Central America (Map 5), and South America and the Caribbean (Map 6). These groupings are based solely on geography and gaps between species and in sampling. They do not represent phylogenetic relationships, rather are meant to facilitate the clarity of keys and diagnoses.

Species concept applied: Species were delineated using a morphological species concept in which species are defined as populations or groups of populations that share a set of phenotypic traits and are distinguishable from other populations or groups.

Results

Examination of museum material confirms the undescribed diversity of Ummidia noted by Bond and Hendrixson (2005) and others. As expected, many previously used characters (specific eye formation, certain carapace characters, etc.) were highly variable and thus insufficient for species determination, in most cases. Results of PCAs of morphological measures emphasize what has long been known of the morphological homogeneity of mygalomorph spiders (Bond and Opell 2002). Plots of PC1 and PC2 for male species (Fig. 2A–C) divided by region show some degree of separation, though species tend to still overlap in morphospace. For females (Fig. 2D–F) the overlap in morphospace among species is extreme, emphasizing the incredible difficulty in delimiting or identifying species based on female specimens.

After examining and comparing large numbers of specimens, a list of putatively taxonomically informative characters was created. These included, but are not limited to, pattern and number of prolateral, retrolateral, and retrolaterodistal spines on the tibia of leg I (mating clasper) of males, palpal tibia and bulb size and embolus length, the presence or absence of a brush or longitudinal comb on the retrolateral face of tarsus IV (Fig. 3), and spermathecal bulb and stalk shape.

Diagnosis

Ummidia can be differentiated from all other halonoproctid genera except Conothele by the presence of a dorsal, glabrous, saddle-like depression on tibia III. Ummidia can be further distinguished from Bothriocyrtum, Cyclocosmia, and Hebestatis by the presence of clavate trichobothria and the absence of lateral sternal sigilla.

General description

Small to large trapdoor spiders. Cephalothorax longer than wide. Pars cephalica highest behind the eyes and sloping posteriorly. Carapace evenly sclerotized; rough/rugose in males, smooth/shiny in females. Fovea procurved, and deep. At least median eyes on tubercle, eye diameter variable. Anterior eye row procurved, posterior eye row relatively straight to slightly recurved or procurved. Carapace of ethanol preserved specimens yellow, reddish, or dark brown. Living spiders usually black to very dark brown. Abdominal coloration generally dark grey, occasionally with a bright white dorsal patch, pale opalescence, or light patches at apodemes.

Sternum usually approximately as wide as long. Lacking lateral sigilla, posterior sigilla large, central, and indistinct. Palpal endites and labium usually with cuspules, size and number of cuspules variable. Palpal endites longer than wide and without anterior lobe. Chelicerae biserially dentate, cheliceral rastellum generally consisting of large spines on a mound.

With two pairs of spinnerets. Posterior median spinnerets (PMS) short and unsegmented. Posterior lateral spinnerets (PLS) relatively short and three segmented with apical segment shortest and domed. Females with single-lobed spermathecae, which are lightly sclerotized with apical bulb. Male palpal bulb with thin embolus.

Females lacking scopulae, but palps, legs I & II with numerous curved, thorn-like spines laterally. Males with scopulae on legs I & II, tarsi cylindrical to proximally enlarged. Anterior legs with few to many prominent spines on the tibia, metatarsus, and tarsus. Posterior legs stouter with heavy spines. Tibia III with dorsal, glabrous, saddle-like depression. Tarsi with mix of clavate and filiform trichobothria arranged in wide band.

Distribution

Ummidia is a wide-ranging genus, found in the southwestern Mediterranean, Central Asia, and in the Americas from as far north as Ohio and Maryland west to Arizona and south to Brazil, including the Greater and Lesser Antilles.

Keys to males by region

As with many members of Mygalomorphae, the highly conserved morphology of Ummidia makes identification non-trivial. In addition, females in particular frequently lack reliably identifiable characters of any sort. The authors have provided keys to the males of species divided by region with notes on females where appropriate, but it should be noted that the keys should be used in combination with other information, to include species descriptions, knowledge of the specimen’s locality, and, for males, the season in which it was collected. In addition, for the reasons mentioned above, there is no key to Ummidia of South America and the Caribbean due to the lack of male material for all species except Ummidia asperula.

Nomen dubium

Ummidia oaxacana (Chamberlin, 1925). Holotype specimen (MCZ1261), from Oaxacana, Mexico, deposited in MCZ is lost and thus no known specimens can be attributed to this name.

Diagnosis

Ummidia audouini can be differentiated from all other co-occurring species in the eastern United States by the presence of a brush on the retrolateral face of tarsus IV and being relatively larger and hairier than other species. Females can be differentiated from all other eastern United States species on the basis of the spermathecae, which curve strongly laterally and coil distally; bulbs facing laterally. In males, eye mound relatively low, eyes relatively small and eye group usually more than twice as wide as long. Palpal bulb relatively small, embolus sinuous. Males disperse from June to August.

Ummidia neilgaimani sp. nov.

Figs 6, 7, Map 3

Type material

HOLOTYPE: 1 ♂ (UMM016), from Virginia Western Community College, Roanoke County, Virginia, United States, 37.2462 -79.97444, 333 m a.s.l., 26.x.1995, coll. MW Donahue, VMNH. PARATYPE: 1 ♀ (UMM240) from Red Oak, Charlotte County, Virginia, United States, 36.7698 -78.63566, 140 m a.s.l., 2.v.1968, coll. WW Baker, AMNH.

Etymology

The specific epithet is a patronym in honor of Neil Gaiman, author of a number of fantasy and horror books with spider-based characters. In one book, American Gods, the main character is tied to the World Tree located “one hour south of Blacksburg,” not far from the type locality of this species.

Diagnosis

Ummidia neilgaimani can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV, which is less defined than the comb in U. rongodwini and U. gingoteague. Males can further be distinguished from U. gingoteague and U. carabivora by lacking spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. Males disperse from September to November.

Ummidia gingoteague sp. nov.

Figs 8, 9, Map 3

Type material

HOLOTYPE: 1 ♂ (UMM003) from Chincoteague National Wildlife Refuge, White Hills Ridge, 1.3 km N toll booth. Accomack County, Virginia, United States, 37.9083 -75.35685, 2 m a.s.l., 26.vi–10.vii.1998, coll. SM Roble, VMNH. PARATYPE: 1 ♀ (AUMS16243) from Newport News, Mariner’s Museum Park, Newport News County, Virginia, United States, 37.0588 -76.48461, 18 m a.s.l., 9.vii.2015, coll. RL Godwin, BME.

Etymology

The specific epithet is a noun taken in apposition and is in reference to the Native American name for the type locality.

Diagnosis

Ummidia gingoteague can be differentiated from all other eastern United States species on the basis of its small size. Ummidia gingoteague can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV, which is more defined than the comb in U. neilgaimani. Males can further be distinguished from U. neilgaimani, U. rongodwini, and U. okefenokee by the presence of spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. Males disperse from May to July.

Pachylomerus carabivorus emarginatus Atkinson, 1886: 134, syn. nov.

Diagnosis

Ummidia carabivora can be differentiated from all other species of Ummidia by the pars cephalica which extends 4/5 (7/10 in other species) the length of the carapace and raised dorsally at the fovea which is 1/3 (1/4–1/5 in other species) the width of the carapace. Males can further be distinguished from all other eastern United States species with tarsal combs by tibia I being relatively more spinose both on the prolateral and retrolateral aspects. Males disperse from June to July.

Etymology

The specific epithet is a patronym named for the first author’s husband and partner Ron Godwin as an expression of gratitude for his love and support throughout her graduate career. The second author likes Ron but not as much as the first author.

Diagnosis

Ummidia rongodwini males can be differentiated from U. audouini, U. neilgaimani, U. gingoteague, U. carabivora, and U. okefenokee by the presence of a white to opalescent dorsal heart patch and from U. richmond by having eyes relatively larger and closer to the anterior margin of the carapace. Males disperse from September to November.

Ummidia okefenokee sp. nov.

Fig. 14, Map 3

Type material

HOLOTYPE: 1 ♂ (UMM163) from Billy’s Island, Okefenokee Swamp, Charlton County, Georgia, United States, 30.8056 -82.33715, 36 m a.s.l., 17.v.1921, AMNH.

Etymology

The specific epithet is a noun taken in apposition and refers to the type locality.

Diagnosis

Ummidia okefenokee can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV, which is more defined than the comb in U. neilgaimani. Males can further be distinguished from U. gingoteague and U. carabivora by lacking spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. Males disperse from May to June.

Ummidia richmond sp. nov.

Type material

HOLOTYPE: 1 ♂ (UMM159) from 6 mi SSW of Perrine, Miami-Dade County, Florida, United States, 25.605 -80.35666, 4 m a.s.l., 16.v.1958, coll. HF Strohecker, AMNH.

Etymology

The specific epithet is a noun taken in apposition and refers to Richmond, originally a small sawmill camp, then the Richmond Naval Air Base, and now known as the Richmond Tract. It contains the most diverse and second largest remaining fragment of critically endangered pine rockland habitat (the largest is in Everglades National Park but is threatened by rising sea levels and will likely lose the title by the end of the century), the habitat in which the spiders were found.

Diagnosis

Ummidia richmond can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV which is more defined than the comb in U. neilgaimani. Males can further be distinguished from U. gingoteague and U. carabivora by lacking spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. It can be differentiated from U. rongodwini by having eyes relatively smaller and more removed from the anterior margin of the carapace. Males disperse from May to June.

Type material

HOLOTYPE: 1 ♂ (UMM286) from Cove Creek, Washington County Arkansas, United States, 35.8167 -94.3956, 583 m a.s.l., 13.x.1962, coll. O Hite, M Hite, AMNH.

Etymology

The specific epithet is a patronym named in honor of Arkansas native General Douglas MacArthur.

Diagnosis

Ummidia macarthuri males can be differentiated from U. rongodwini by lacking a pale dorsal heart patch and from U. audouini and U. rosillos by lacking a brush on the retrolateral face of tarsus IV. Comb on tarsus IV is less distinct than that of U. funerea and U. colemanae. Males can be differentiated from all geographically proximate species other than U. rongodwini by the lack of prolateral spines on tibia I. Males disperse from September to October.

Ummidia pygmaea Brignoli, 1983: 117.

Diagnosis

Ummidia beatula are relatively small spiders which can be differentiated from U. rongodwini by males lacking a pale dorsal heart patch and from U. audouini and U. rosillos by lacking a brush on the retrolateral face of tarsus IV. In males, the comb on tarsus IV is less distinct than that of U. funerea and U. colemanae. Males can be differentiated from U. macarthuri and U. rongodwini by the presence of prolateral spines on tibia I. Males disperse from April to June.

Diagnosis

Ummidia colemanae is an extremely small species found in southern Texas. Males can be differentiated from U. rongodwini by the absence a pale dorsal heart patch and from U. audouini and U. rosillos by lacking a brush on the retrolateral face of tarsus IV. Comb on prolateral face of tarsus IV is more distinct than that of U. beatula, U. mercedesburnsae, and U. macarthuri. Males disperse from April to June.

Etymology

The specific epithet is a patronym in honor of Dr. Mercedes Burns the first female African American arachnologist (to our knowledge).

Map 4. 

Locality records for western United States and northern Mexico species.

Diagnosis

Ummidia mercedesburnsae can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and brush on the retrolateral face of tarsus IV. Males can be differentiated from U. rosillos, U. modesta, U. timcotai, U. gabrieli, and U. rodeo by having an embolus with an even curve and from U. paulacushingae, U. waunekaae, U. gertschi, U. timcotai, and U. rodeo by having relatively fewer spines on the retrolateral face of tibia I. Females can be differentiated from all other geographically proximate species except U. modesta by having spermathecae with strong medial bend. Males disperse in August.

Scale bars: 1.0 mm (A–D), 4.0 mm (E).

Diagnosis

Ummidia paulacushingae can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and brush on the retrolateral face of tarsus IV. Males can be differentiated from U. rosillos, U. modesta, U. timcotai, U. gabrieli, and U. rodeo by having an embolus with an even curve and from U. mercedesburnsae by having relatively more spines on the retrolateral face of tibia I. Males can also be differentiated from all other geographically proximal species except U. gertschi by having a distinct comb comprising close set heavy setae on the retrolateral face of tarsus IV.

Type material

HOLOTYPE: 1 ♂ (UMM559) from northeast of Albuquerque, Bernalillo County, New Mexico, United States, 35.1303 -106.55215, 1667 m a.s.l., 30.x.1963, coll. L. Oakley, AMNH.

Etymology

The specific epithet is a patronym in honor of Annie Dodge Wauneka (1910–1997), influential member of the Navajo Nation who worked tirelessly to improve education and health of the Navajo. Among other awards, she was bestowed the United States Presidential Medal of Freedom in 1963 by President Lyndon B. Johnson.

Diagnosis

Ummidia waunekaae can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and brush on the retrolateral face of tarsus IV. Males can be differentiated from U. rosillos, U. modesta, U. timcotai, U. gabrieli, and U. rodeo by having an embolus with an even curve and from U. mercedesburnsae by having relatively more spines on the retrolateral face of tibia I. Males can also be differentiated from U. gertschi and U. modesta by lacking a distinct comb on the retrolateral face of tarsus IV. Males disperse in October.

Etymology

The specific epithet is a patronym named for Dr. Willis J. Gertsch, famous arachnologist who put decades of work into a revision of Ummidia and the then Ctenizidae but was unable to finish before his passing; and whose notes, stored in the archives of the American Museum of Natural History, proved invaluable in the completion of this revision.

Diagnosis

Ummidia gertschi can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and brush on the retrolateral face of tarsus IV. Males can be differentiated from U. rosillos, U. modesta, U. timcotai, U. gabrieli, and U. rodeo by having an embolus with an even curve and from U. mercedesburnsae by having relatively more spines on the retrolateral face of tibia I. Males can also be differentiated from all other geographically proximal species except U. paulacushingae by having a distinct comb on the retrolateral face of tarsus IV. Females can be distinguished from all other geographically proximal species by possessing simple, straight spermathecae. Males disperse from July to August.

Ummidia timcotai sp. nov. from Gila Co., Arizona A male habitus illustration UMM161 B female habitus illustration UMM666. Scale bars: 4.0 mm.

Etymology

The specific epithet is a patronym named for Timothy Cota who has collected many specimens used in this revision to include the female paratype of this species and has studied the group’s natural history for many years.

Diagnosis

Ummidia timcotai can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and from all geographically proximal species except U. rosillos by the presences of a brush on the retrolateral face of tarsus IV. Males can be differentiated from U. mercedesburnsae, U. paulacushingae, U. waunekaae, and U. gertschi by having a sinuous embolus and from all geographically proximal species by tibia I being very spinose. Females can be differentiated from U. gertschi, U. modesta, and U. mercedesburnsae by having spermathecae that curve laterally. Males disperse from July to August.

Etymology

The specific epithet is a patronym in honor of musician and human rights activist Peter Gabriel.

Diagnosis

Ummidia gabrieli are relatively large spiders (males CL 8.6–10.6, other species CL 4–7.5) and can be differentiated from males of all other geographically proximal species by the lack of prolateral spines on metatarsus and tibia I, having a palpal tibia that is > 3 ´ long as wide, by having tarsi which are relatively short and tapered distally, and by the presence of a dorsal opalescence on the abdomen. Males can be differentiated from U. mercedesburnsae, U. paulacushingae, U. waunekaae, and U. gertschi by having a sinuous embolus. Females can be differentiated from U. gertschi, U. modesta, and U. mercedesburnsae by having spermathecae that curve laterally. Females can be differentiated from U. pesiou by having significantly fewer endite cuspules (28 vs 59) and having rastellar spines not extending up cheliceral face, and from U. pustulosa by having the sternum roughly as wide as long.

Type material

Female holotype presumed lost. NEOTYPE 1♀ designated here (NHMUK1071) from Amula (now Jalisco), Mexico, 20.6934 -103.3567, 1550 m a.s.l., H.H. Smith 1898, NHMUK. The original type locality is simply listed as “Guanajuato, Mexico” in the original description which neighbors the locality of the neotype designated, Jalisco, Mexico. Given the carapace length to width ratio noted in Becker’s (1879) description and the illustration of the sternum (Becker 1881, fig. 2b) we can be reasonably confident that designation of this specimen as the neotype is consistent with what is known of the originally described specimen.

Diagnosis

Females of U. pustulosa can be differentiated from U. pesiou and U. rodeo by having the carapace and sternum 1.2× long as wide (roughly long as wide in other species) and from U. gabrieli by having relatively more endite cuspules (43 vs 28).

Map 5. 

Locality records for southern Mexico and Central American species.

Diagnosis

Ummidia huascazaloya can be differentiated from U. anaya by the presence of a defined comb on the retrolateral face of tarsus IV in males and females. U. huascazaloya males can be further differentiated from U. anaya by having a palpal tibia (3.25× long as wide vs 1.85×) and tarsus IV (3.6× long as wide vs 2.9×) which are more elongate as well as having fewer, larger endite cuspules (10 vs 22). Males can be differentiated from U. cuicatec and U. zilchi by having a sinuous embolus without a strong bend and from U. cuicatec, U. zebrina, U. brandicarlileae, and U. yojoa by having more spines on the prolateral face of tibia I (11 vs 0-2). Males can be differentiated from U. riverai by lacking a pale dorsal heart patch on the abdomen. Females can be differentiated from U. gabrieli, U. pesiou, U. rodeo, U. pustulosa, and U. frankellerae by having spermathecae that bend medially then anteriorly. Males disperse in June.

Figure 43. 

Ummidia cuicatec sp. nov. from Oaxaca, Mexico. A male habitus illustration UMM154 B female habitus illustration UMM415. Scale bars: 4.0 mm.

Diagnosis

Ummidia cuicatec is a relatively large species in which males can be differentiated from all other species by having a long, sinuous embolus with an extreme distal curve. Males can be differentiated from U. anaya, U. huascazaloya, U. zilchi, U. riverai, and U. hondurena by having fewer spines on prolateral (2 vs 7-28) and retrolateral (10 vs 15-42) faces of tibia I and from U. riverai by lacking a pale dorsal heart patch on the abdomen. Females can be differentiated from all other geographically proximal species except U. pustulosa and U. frankellerae by having spermathecae that curve laterally and end in a distal coil with bulbs facing laterally. Males disperse in June.

Type material

HOLOTYPE ♂ (UMM158) from Tekom, Yucatán, Mexico, 20.0603 -88.26541, 96 m a.s.l., 17.iv.1940, coll. T. Sanderson, AMNH. PARATYPE: 1 ♀ (UMM576) from Chichén Itzá, Yucatán, Mexico, 20.6826 -88.56865, 38 m a.s.l., 16.vii.1952, coll. J Ballister, D Ballister AMNH.

Etymology

The specific epithet is in honor of Brandi Carlile, an American singer-songwriter who, along with Tim and Phil Hanseroth, established the Looking Out Foundation, which raises money and awareness for numerous causes to include supporting child victims of war, world hunger, LGBT rights, and the empowerment of women. Carlile founded the annual Girls Just Wanna Weekend Festival to counter the lack of female representation at mainstream music festivals, which takes place near the type locality for this species.

Diagnosis

U. brandicarlileae can be distinguished from all other geographically proximal species except U. yojoa by lacking either a defined brush or comb on the retrolateral face of tarsus IV. Males can be differentiated from U. cuicatec and U. zilchi by having a sinuous embolus without a strong bend, from U. huascazaloya, U. anaya, U. zilchi, U. riverai, and U. hondurena by having fewer spines on prolateral (2 vs 7-28) face of tibia I and from U. riverai by lacking a pale dorsal heart patch on the abdomen. Males can be further differentiated from all other geographically proximate species by having tarsi I relatively short and thickened proximally. Females can be differentiated from U. cuicatec, U. frankellerae and U. matagalpa by having spermathecae that bend medially then anteriorly. Males disperse from April to July.

Etymology

The specific epithet is a patronym in honor of Mario Dary Rivera, and environmentalist and patriarch of Guatemala’s environmental movement. Rivera was instrumental in the creation of the Quetzal Biotope (Biotopo de Mario Dary Rivera) near where the type specimen was collected.

Diagnosis

Ummidia riverai males can be distinguished from all other geographically proximate males except U. rugosa by the presence of a pale dorsal heart patch on the abdomen and from all geographically proximate species by the presence of a defined comb of alternating long and short spinules on the retrolateral face of tarsus I. Males can be further differentiated from U. huascazaloya, U. anaya, U. cuicatec, U. brandicarlileae, U. zebrina, U. yojoa, and U. varablanca by having relatively more spines on the prolateral (19 vs 0-11) and retrolateral (22 vs 1-17) faces of tibia I.

Ummidia frankellerae sp. nov.

Fig. 49, Map 5

Type material

HOLOTYPE: 1 ♀ (BMEA101781) from Las Cuevas Field Station, 15 kilometers east of Caracol, Cayo, Belize, 16.733 -88.9861, 650 m a.s.l., 29.vi-3.vii.2019, coll. JE Bond, BME.

Etymology

The specific epithet is a patronym in honor of Dr. M. Francis Keller. Fran was the leader of the bioblitz in Belize, associated with UC Davis and the Bohart Insect Museum, when this specimen was collected.

Diagnosis

Ummidia frankellerae females can be differentiated from all species by the presence of patches on either side of the spinnerets which are, in color and texture, similar to the book lungs and from all other geographically proximate species by the presence of a brush consisting of many spinules embedded in dense setae on the retrolateral face of tarsus IV. Females can be distinguished from all geographically proximate species except U. pustulosa by the sternum being relatively longer that wide (1.2× long as wide vs subequal in other species) and from all except U. cuicatec by having spermathecae which curve laterally with a distal coil.

Ummidia zilchi Kraus, 1955b: 7; Type Material. HOLOTYPE 1♂ (8569_1) from San Salvador, El Salvador, 13.6921 -89.2196, 700 m a.s.l., A. Zilch, 5.viii.1957, deposited in Senckenberg Museum, examined. Three paratypes (8568, 8570, 8571) associated with specimen. Specimens 8570 and 8571 are immatures and 8568 is misidentified (see Ummidia hondurena sp. nov.)

Ummidia zilchi Bücherl, 1957: 382.

Diagnosis

Ummidia zilchi males can be distinguished from all geographically proximate species except U. huascazaloya by the palpal tibia being elongate (3.5×long as wide) and a relatively short embolus (half the length of the palpal tibia) with an even curve. Males can be differentiated from all geographically proximate species except U. zebrina and U. carlosviquezi by having a defined comb of spinules on the retrolateral face of tarsus IV. Males can be further differentiated from U. huascazaloya, U. anaya, U. cuicatec, U. brandicarlileae, U. zebrina, U. yojoa, and U. varablanca by having relatively more spines on the prolateral (19 vs 0-11) and retrolateral (36 vs 1-17) faces of tibia I.

Type material

HOLOTYPE: 1 ♂ (UMM172, AMNH) from Honduras, 14.5036 -86.32069, 650 m a.s.l.. PARATYPE: 1 ♀ (8568, SMF) from Finca San Jorge, Santa Ana, Santa Ana, San Salvador, 13.9778 -89.56475, 1000 m a.s.l., 25.iv.1951. Female paratype was originally misidentified as Ummidia zilchi (Krauss, 1955).

Etymology

The specific epithet is a noun (feminine, singular) taken in apposition and is in reference to the type locality and its people.

Diagnosis

Ummidia hondurena can be differentiated from all other geographically proximate species except U. riverai and U. rugosa by the presence of a comb of alternating large and small strong setae on the retrolateral face of tarsus IV (Fig. 3C). Males can be differentiated from U. zilchi, U. carlosviquezi, U. varablanca, and U. quepoa by possessing a sinuous embolus, rather than one with an even single curve and from U. yojoa and U. varablanca by having many more prolateral (26 vs 0) and retrolateral (29 vs 2-3) spines on tibia I. Males can be further distinguished from U. riverai and U. rugosa by lacking a pale dorsal heart patch on the abdomen. Females can be distinguished from all geographically proximate species except U. rugosa and U. erema by having spermathecae which bend first medially and then anteriorly.

Etymology

The specific epithet is a noun taken in apposition and is in reference to the type locality, Lake Yojoa.

Diagnosis

Ummidia yojoa males are relatively stocky spiders and can be differentiated from all geographically proximate species by the presences of a soft brush on the retrolateral face of tarsus IV and from all except U. zebrina and U. varablanca by lacking prolateral spines and having very few retrolateral spines (3 vs 10-44) on tibia I. Males can be further distinguished from U. zilchi, U. carlosviquezi, U. varablanca, and U. quepoa by possessing a sinuous embolus, rather than one with an even single curve and from U. riverai and U. rugosa by lacking a pale dorsal heart patch.
