DiagnosisDIAGNOSIS (DIAGNOSTIC CHARACTERS). The species differs from all other Lepidophyma except L. pajapanense in having the paravertebral rows composed of a nearly uninterrupted string of subequal tubercles; from L. pajapanense, L. lipetzi, and L. chicoasense in having 29 or fewer femoral pores; from all except L. mayae, L. pajapanense, L. lipetzi, and L. sylvaticum in having 30 or more large paravertebrals; and from L. radula, L. smithii, L. tarascae, L. lineri, and L. occulor in having 30 or more lateral tubercle rows nearly full-term embryos. At their study site located at 900 m on Volcán Santa Marta, Castillo-Cerón and López-González (1990) found that females gave birth to three to five young in late June and July; that activity occurred in the day; that stomach contents consisted of insects, amphipods, gastropods, and plant material; and that only 1 of 11 specimens preserved was male (from BEZY & CAMARILLO 2002).

REMARKS. Lepidophyma tuxtlae is most similar in scalation to L. pajapanense, with which it is sympatric, but the two differ markedly in color and color pattern (Figs. 23, 30). The widely scattered populations of L. tuxtlae have differences in the means of several features of scalation, but there is broad overlap in the observed limits of variation and they are highly similar in color pattern (Fig. 30). The ecological and biogeographic relationship between L. tuxtlae and L. pajapanense in the Tuxtlas merits additional study. Castillo-Cerón and López-González (1990) noted that L. pajapanense is the more abundant at the Estación de Biología Tropical ‘‘Los Tuxtlas,’’ whereas L. tuxtlae predominates at their study site on Volca´n Santa Marta (from BEZY & CAMARILLO 2002).
