DiagnosisDiagnosis: Xantusia sherbrookei 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 (32–36 vs. 40–49); from X. sanchezi in having fewer undivided lamellae beneath the fourth toe (1–4 vs. 7–9); from X. jaycolei in having conspicuous femoral pores in females (pores well developed vs. absent or marked by faint shallow depressions in females; Fig. 4); from X. wigginsi in having fewer transverse rows of ventrals between the vent and the gular fold (29–32 vs. 33–35); from X. extorris in having a higher fifth supralabial (Fig. 8 in BEZY et al. 2008); from X. vigilis in having a higher seventh supralabial (Fig. 8); and from X. gilberti in having small scales bordering the labium posterior to the fifth infralabial (vs. enlarged sixth and seventh infralabials bordering the labium; Fig. 5) and in having larger dorsal spots (encompassing two to three scales vs. one scale) scattered across the dorsum (vs. concentrated on the sides of the body) and a more vivid postorbital stripe (from BEZY et al. 2008).
