and McCarty Caves, which are known only fromjuveniles.Texella sp.Note.-Two females from Marguerite Caveresemble those from Haby Salamander Cave (T.harden;) and Robber Baron Cave (T. cokendolpheri)but differ in possessing a tubercle ventrally on TrIV.On the basis of this and, especially, their isolation,these specimens probably represent a new species.The positive identification of this population willawait the discovery of a male.Material Examined.-UNITED STATES: Texas:Med;na Co.: Marguerite Cave, 28 Apr. 1984(S. Harden, TMM), 1 female; 5 May 1984 (R.Waters, TMM), 1 female.The bi/obara InfragroupDiagnosis.-Males of the single known speciescomprising this infragroup may be distinguishedfrom other Texella by the following combination ofcharacters: epigean; TC = 3-5-4-5; BK large, bilobed;PSL intricately folded, apically hooked; SAwith lateromedial prong, lacking carina; apical halfof S tubular (Figs. 113-117).Range.-Known only from Kerr Co., Texas(Maps 3,4).Texella bi/obata, new speciesFigs. 113-117.Diagnosis.-As for infragroup.Type.-Male holotype from Raven Ranch, KerrCounty, Texas (Dec. 1939; S. and D. Mulaik),deposited in AMNH.Etymology.-The specific name is a reference tothe bilobed basal knob of the glans, unique to thisspecies.Description.-Total body length, 1.23-1.41.Scute length, 0.84-0.97. Leg II length, 2.41-2.44.Leg II/Scute length, 2.62-2.80. (N = 3).Color brownish orange. Body coarsely rugose;tubercles scattered on eye mound, pars thoracica,tergite margins, and coxae. Carapace with 2 pairsAT. Eye mound broadly conical, retina and corneapresent. Palpal megaspines: trochanter, one ventral;femur, one mesoapical; patella, two mesal;tibia, three mesal (mesoapical small). Tarsal count:3-5-4-5.Male (holotype): Total body length, 1.23. Scutelength, 0.92; width, 0.92. Eye mound length, 0.23;width, 0.23. Leg II length, 2.41. TrIV spurlength, 0.05. POP absent.Penis (Figs. 113-117): VPP with 2 dorsal, 3lateral, and 2? ventral setae; lateral setae short,dorsal and ventral setae medium to long; ASapparently broken, base distinct, large. Glans: BKbifurcate, large; ML broad; PSL complex, withapical hook. S with apical third straight, tube-like;BF present; SA with lateral prong, lacking carina.Female (paratopotype): Total body length, 1.41.Scute length, 0.97; width, 1.03. Eye mound length,0.21; width, 0.26. Leg II missing. TrIV withventral tubercle.Ovipositor damaged; apical teeth present.Note.-The available specimens are old and extremelybrittle; all have somewhat damaged genitalia.In both males the apical spine appears to bebroken and is represented by a clearly visible andquite large basal portion.Other Material Examined (Paratypes).- UNIT­ED STATES: Texas: Kerr Co.: Raven Ranch,Dec. 1939 (S. and D. Mulaik, AMNH), 1 male, 1female.Distribution.-Known only from the typelocality (Maps 2-4).The reddell; SubgroupDiagnosis.-The males of this subgroup aredistinguished from all other Texella by the followingcombination of characters: PSL claw-like (except inT. fend; and T. homi); SA produced into a scroll orprong (except in T. hom;); apical half of S spatulate(except T. fendi and T. homi).Range.-Known only from central Texas (Maps3,4).The reddelli InfragroupDiagnosis.-The males of this infragroup aredistinguished from all other Texella by the followingcombination of characters: S apically spatulate; SAscrolled, clips onto the PSL (Fig. 7).Distribution.-Known only from the caves ofTravis and Williamson Counties, Texas (Maps 3-5).Texella reddelli Goodnight and GoodnightFigs. 118-123.Texella reddelli Goodnight and Goodnight, 1967:7(male holotype from Bee Creek Cave, Austin,Travis County, Texas, in AMNH, examined).207
