Notes.-The type locality was erroneouslypublished (Goodnight and Goodnight, 1967) as"Pine Creek <strong>Cave</strong>. "Males will be necessary to verify the inclusion ofspecimens from <strong>Cave</strong> Y and Bandit <strong>Cave</strong> in thisspecies. However, the females resemble those fromBee Creek <strong>Cave</strong> and Jester Estates <strong>Cave</strong> in overallappearance and clearly lack the apomorphies of theother two species in the immediate vicinity, T.spinoperca and T. mulaiki.Texella reyesi, new speciesFigs. 7, 124-159.Texella mulaiki Goodnight and Goodnight, 1942.Goodnight and Goodnight, 1967:6 (in part,specimens from Cotterell, Beck Ranch, andMan-With-A-Spear <strong>Cave</strong>s only).Texella reddelli Goodnight and Goodnight, 1967:7(in part, specimens from Tooth, Weldon, andBone <strong>Cave</strong>s only): Mitchell and Reddell, 1971:46.Diagnosis.-See discussion under T. reddelli andTable 3.Type.-Male holotype from Bone <strong>Cave</strong>, WilliamsonCounty, Texas (4 June 1989; W. Elliott, J.Reddell, M. Reyes), deposited in CAS.Etymology.-The specific name is a patronym inhonor of Mr. Marcelino Reyes, collector of this andmany other species of Texella.Description.-Total body length, 1.41-2.67.Scute length, 1.26-1.69. Leg II length, 6.10-11.79. Leg II1Scute length, 4.30-8.68. (N = 85).Color pale orange. Body finely rugose; fewsmall tubercles on eye mound, pars thoracica, andcoxae; tergite margins smooth. Carapace with 0-2pairs of anterior tubercles. Eye mound broadlyconical, retina absent, cornea well developed, reduced,or absent. Palpal megaspines: trochanter, 1ventral; femur, 1 mesoapical; patella, 2 mesal; tibia,3 mesal. Tarsal count from 3-5-5-5 to 4-7-6-8.Male (holotype): Total body length, 1.59. Scutelength, 1.28; width, 1.31. Eye mound length, 0.26;width, 0.28. Leg II length, 9.60. TrIV spurstraight; length, 0.56. POP length, 0.26.Penis (Figs. 145-147): VPP rounded apically;with 2 dorsal, 17 lateral, and 4 ventral setae; ASbent, apically pointed, length 0.05. Glans: BK narrowlyconical; ML long; PSL claw shaped. S long,curved, ventrally carinate, apically spatulate; BFwell developed; SA laterally scrolled, clips ontoPSL.(paratype, Tooth <strong>Cave</strong>): Total body length,2.13. Scute length, 1.46; width, 1.54. Eye moundlength, 0.34; width, 0.38. Leg II length, 6.67.TrIV spur bent; length, 0.59. POP length, 0.36.Penis (Figs. 7, 136, 138, 148): Similar toholotype except <strong>for</strong> the following: VPP with 12lateral setae; AS slightly shorter (0.04), apicallybifurcate.Female: (paratopotype) Total body length,1.92. Scute length, 1.33; width, 1.33. Eye moundlength, 0.26; width, 0.28. Leg II length, 9.64.TrIV with tiny ventral tubercle.Ovipositor: cuticle intricately folded; surfacesparsely covered with tiny microspines; 1 pair apicalteeth present; setal pattern: 2 pairs dorsal, 4 lateral,1 ventral.Juvenile: Color white to yellowish white;integument apparently unsclerotized. Tarsal countof middle instars 2-2-3-3 and 2-2-3-4; tarsomeres ofearlier instars not discernable. Six immature specimenshave short trochanteral spurs; one of these,presumably a penultimate, also has a short POP.Variation.-This species is extremely polymorphic,most notably in troglomorphic characters. Thecharacters examined are presented in Table 3. Acline is apparent, with the more troglomorphicindividuals occurring at the northern end of thedistribution.The size of sexually dimorphic structures appearsto vary with body size: the TrIV spur (Figs. 128,129) varies from 0.35-0.82; the POP (Figs. 132,133) varies from 0.09-0.51.A female from Tooth <strong>Cave</strong> (Figs. 152-155) isunique in having a hyperexpanded ovipositor (seediscussion under morphology). A specimen fromCotterell <strong>Cave</strong>, the second largest female specimen,is aberrant in having both a tiny POP (Figs. 134,135) and a short TrIV spur (Fig. 130). A similar(although smaller) TrIV spur is present on a femalefrom Beck Ranch <strong>Cave</strong>.Natural History.-"Most specimens of thisspecies have been taken on the underside of rockslightly buried in soil. In all instances they havebeen found only in the more remote parts of thecaves. None have been found in twilight, with theexception of the single juvenile from NewComanche Trail <strong>Cave</strong>. This specimen was found onthe talus slope below the entrance the day after aheavy rain had saturated the surface of the slope."(J. Reddell, personal communication)Other Material Examined (paratypes).- UNIT­ED STATES: Texas: Travis Co.: 14 mi NW Austin,McDonald <strong>Cave</strong>, 18 May 1984 (D. Pate, J.Reddell, and M.
