(0.36); chela (without pedicel) 2.00 (1.91) by 0.59(0.555); hand (without pedicel) 0.895 (0.84) by0.665 (0.635); pedicel 0.19 (0.19) long; movablefinger length 1.17 (1.16). Leg IV: entire femur 1.04(1.02) by 0.245 (0.235); tibia 0.955 (0.96) by 0.14(0.13).Etymology.-The new species is named intermediafor its morphological characters intermediate betweenthose of T. comanche and the other morehigWy cave-adapted forms.Remarks.-It is interesting to note that, as in T.comanche (above), the depth of the chelal hand ofthis species is greater than the breadth. As no noncavespecies of the genus is yet known, it is impossibleto judge whether or not this is a primitivecharacter.The discovery of yet another species of Tartarocreagrisin the area of Travis and Williamson Countiesemphasizes the fact that much speciation hasgone on in the caves here. It is to be expected thatfurther collecting will yield more new species and itis to be hoped that collections in epigean habitatswill turn up some "ancestral" surface forms.Tartarocreagris, sp. indet.A lone tritonymph was collected in LakeLineCave, Williamson County, Texas, 7 February 1990,by M. Reyes and J. Reddell mounted on slide(FSCA). As LakeLine Cave lies about midway betweenMcDonald Cave and Beck Ranch Cave whereadults of Tartarocreagris reddelli have been found,it is reasonable to believe that this nymph belongs tothat species; however, a definite identification is impossibleat this time.Hesperochernes unicolor (Banks)A male of tills species was taken by Berlese separationof leaf litter from the entrance area of Lake­Line Cave, Williamson County, Texas, 13 February1990, by J. Reddell and M. Reyes; mounted onslide (FSCA). This specimen is smaller than, butgenerally similar to, the female from Ezell's cavementioned above. Also, it is quite similar to themale from a pack rat nest in Cameron County,Texas, which was tentatively assigned to this speciesby Hoff and Clawson 1952).This is Publication No. N.S.-59 of the Texas Memorial Museum.153
