Diagnosis.-This species is most easily distinguishednumber of setae on the VPP [10 lateral setae in T.\\Ifrom T. reyesi by its somatic characters. T. reddelli (Figs. 120, 121); 12-20 in T. reyesi (Figs.reddelli is only slightly troglomorphic and has well 7, 136-147)]. The two species are clear!y verydeveloped eyes, relatively shorter legs (LII/SL =3.8-5.2), and a higher number of AT (3-5 pairs;closely related and, using the standards of genitalicdistinctness applied to other Texella species, mayFigs. 118, 119). T. reyesi lacks retinae, has longer even be considered conspecific. However, givenlegs (LII/SL = 4.3-8.7), and has a lower number of that the two groups can be distinguished, they areAT (virtually all specimens with 2-0 pairs; Figs. treated here as species. A comparison of most of124, 125, 127).these characters is given in Table 3.The only genitalic differences so far detected are Description.-Total body length, 1.90-2.18.the relative lengths of the AS [shorter in T. reddelli Scute length, 1.21-1.66. Leg II length, 4.92-7.59.(Fig. 123) than in T. reyesi (Figs. 148-151)] and the Leg II/Scute length, 3.81-5.20.
