apical region which loses the apical fold, andtwisted, with the lateral prongs becoming mesal(compare Figs. 26-29 to 42 and 43). Similarchanges, but of a lesser magnitude, occur to the PSLof T. shoshone.Natural History.-Specimens were collected beneathdecaying wood debris, along with several additionalinvertebrates. Given the isolation ofKokoweef Crystal Cave, it is likely that much of thefauna is endemic. At present, a species of spider,Usofila n. sp. (Telemidae), is known only from thiscave (Gertsch, personal communication).Other Material Examined (Paratypes).- UNIT­ED STATES: California: San Bernardino Co.:Kokoweef Crystal Cave, 30 Dec. 1968 (T. Briggs,B. Lum, and G. Leung, CAS), 7 males, 1 female; 1Apr. 1972 (T. Briggs and D. Ubick, CDU,AMNH), 2 males, 1 female.Distribution.-Known only from the type locality(Map 1).Texella shoshone, new speciesFigs. 34-41,44.Diagnosis.-Males of this species may be distinguishedfrom all others in the group by the followingcombination of characters: VPP thin,parallel-sided; AS apparently absent; PSL2 slender;and GO with 2 pairs of apical tubercles (also foundin females) (Figs. 38-41, 44). This species is alsodistinct somatically in having the body surface studdedwith large tubercles; especially prominent on thetergite margins and anal operculum (Figs. 34-35).Type.-Male holotype from Shoshone Cave,Inyo County, California (29 Dec. 1971; T. Briggs),deposited in CAS.Etymology.-The specific name is a noun in appositiontaken from the type locality.Description.-Total body length, 1.40-1.49.Scute length, 0.90-1.05. Leg II length, 3.82-4.23.Leg II/Scute length, 3.86-4.24. (N = 3).Color yellowish orange. Body coarsely rugose;large tubercles on eye mound, pars thoracica, coxae,and especially tergite margins and anal operculum.Carapace with 2 pairs of large anterior tubercles.Eye mound rounded, dorsally flattened, eyes welldeveloped. Palpal megaspines: trochanter, 1 ventral;femur, 1 mesoapical; patella, 1 mesal; tibia, 2mesal. Tarsal count: 3-5-4-5.Male (holotype): Total body length, 1.49. Scutelength, 1.05; width, 1.08. Eye mound length, 0.23;width, 0.23. Leg II length, 4.05. TrIV spur relativelystraight; length, 0.25. POP absent. GO with2 pairs of apical tubercles.Penis (Figs. 38-41): VPP slender, parallel sided,apically pointed; with 2 dorsal, 6 lateral, and 4 ventralsetae; AS apparently absent. Glans: BK absent;ML absent or possibly represented by two laterallobes; PSL long, ribbon-like, apically folded; PSL2slender, apically directed. S long, compressed,relatively straight; SA represented by basolateralcarina; BF absent.Female (paratopotype): (The single availablespecimen was badly damaged during dissection.)Similar to males in size and general appearance. GOwith two pairs of prominent apical tubercles. Ovipositorwithdrawn, apical setae visible. Tr IV withone ventral tubercle.Note.-The PSL apparently inflate during glansexpansion (see note in T. kokoweef and compareFigs. 38-41 to 44).Natural History.- This species is known onlyfrom Shoshone Cave. This cave has a thermalspring, which maintains conditions at about 25°Cand 100% humidity. The habitat and cave conditionsare more thoroughly described by Briggs andHom (1972). Shoshone Cave is located in a saltbushdesert and has a rich fauna which, as a result of itsisolation, is high in endemicity. In addition to T.shoshone, the fauna includes an endemic shizomid[Hubbardia shoshonensis (Briggs and Hom, 1972)],milliped (Colactis briggsi Shear 1974), cricket(Ceuthophilus n. sp.), and carabid (Rhadine n. sp.).Other Material Examined (Paratypes).- UNIT­ED STATES: California: Inyo Co.: ShoshoneCave, 29 Dec. 1971 (T. Briggs, CAS), 3 males, 1female.Distribution.-Known only from the type locality(Map 1).Texella deserticola, new speciesFigs. 45-47.Diagnosis.-This species may be distinguishedfrom the males of other species in the group by thecombined presence of a medium-sized AS, shortclaw-like PSL, and strongly reduced PSL2 (Figs.45-47).Type.-Male holotype from Whitewater Canyon,Riverside County, California (8 Apr. 1979; D.Ubick), deposited in CAS.Etymology.-The species name IS Latin for"dweller of the desert".Description.-Male (holotype): Total bodylength, 1.33. Scute length, 0.92; width, 0.85.Eyemound length, 0.21; width, 0.23. Leg II length,3.13. LII/SL = 3.40.183
