| Diagnosis | Diagnosis: A species of the ocellifer group with granules in the supraorbital semicircles, and no anal spurs in males. Cnemidophorus venetacaudus differs from all the other members of the ocellifer group by the absence of stripes in the dorsum and a high number of femoral pores. In addition, it differs from C. ocellifer, C. nativo, C. mumbuca, and C. jalapensis by having 34–45 (x= 38) femoral pores (24–26, x= 24 in C. nativo; a maximum of 20 in all other species); 10 longitudinal rows of ventral scales (6–8), 30–32 (x= 31.2) transverse rows of ventrals (29– 32, x= 30.8 in C. nativo, a maximum of 29 in all other species), 31–34 (x= 31.7) scales around tail (a maximum of 30 in all other species), 114–129 (x= 119.5) scales around midbody (91–122, x= 104 in C. jalapensis, a maximum of 117 in all other species), 6 superciliaries (5), 1–2 row of spurs in the heel in males (absent), interparietal nar- rower than other parietals (wider), humeral region with one row of distinctive enlarged scales (2–4 not so enlarged), and no enlarged scales in temporal region posterior to third subocular (present). Cnemidophorus veneta- caudus differs from C. abaetensis by having 34–45 (x= 38) femoral pores (27–31, x= 24), 190–218 (x= 204.8) dor- sal scales (210–240, x= 221.8), interparietal narrower than other parietals (wider), second supraocular totally separated from frontal by supraocular granules (second supraocular contacts frontal), four supraoculars (usually 3), dorsal stripe absent (present), stripe in the tail absent (present). Cnemidophorus venetacaudus differs from C. litto- ralis by having 34–45 (x= 38) femoral pores (28–36, x= 32.6 in C. littoralis), 190–218 (x= 204.8) dorsal scales (168–191, x= 174.9), interparietal narrower than other parietals (wider), frontonasal never divided (35.6 % of indi- viduals with a divided frontonasal, according to Rocha et al., 2000), second supraocular separated from frontal by supraocular granules (second supraocular contacts frontal), dorsal stripe absent (present), and stripe in the tail absent (present) [from ARIAS et al. 2011; BASTOS DA SILVA & AVILA-PIRES 2013 also present a diagnosis]. |
| Comment | Group: this species belongs to the ocellifer group, |
| Etymology | The specific epithet, veneta, is a Latin adjective meaning ‘‘bluish,’’ and the Latin superlative suffix caudus, meaning ‘‘tail.’’ The name ‘‘bluish tail’’ is an allusion to the characteristic blue coloration of the tail of this species. |
