| Diagnosis | Diagnosis: Xantusia jaycolei differs from all other species of the genus except X. henshawi, X. gracilis, X. arizonae, and X. bezyi in that the females lack well-developed femoral pores (pores absent or marked by shallow depressions vs. a conspicuous glandular pore; Fig. 4). It differs from X. riversiana, X. henshawi, X. gracilis, and X. bolsonae in having fewer longitudinal rows of ventral scales at midbody (12 vs. 14–16); from X. arizonae, X. bezyi, and X. sierrae in having fewer dorsal scales around midbody (36–39 vs. 40–49); from X. sanchezi in having more scales around the second caudal whorl (32–36 vs. 25–28); and from X. gilberti in having small scales bordering the labium behind the fifth infralabial (from BEZY et al. 2008). |
