Diagnosis | Diagnosis: A species of Cnemidophorus belonging to the ocellifer complex and distinguished from all other members by the following combination of characters: (1) small size, maximum SVL 56 mm, mean SVL 49.31 6 5.49 mm, n 5 51; (2) 11–16 femoral pores; (3) 19–26 scales around tail; (4) 22–37 fourth toe lamellae; (5) paravertebral stripes interrupted; (6) dorsolateral stripes continuous; (7) lateral spots absent; (8) hindlimb spots absent; (9) preanal spur absent; (10) ventral caudals smooth; (11) dorsal caudals keeled; and (12) gular region and ventrolateral aspect of head and body lime-green. Cnemidophorus jalapensis differs from C. mumbuca in having 11– 16 femoral pores (14–20 in C. mumbuca), dorsolateral stripes continuous (interrupted, not reaching supraciliary region), lateral spots absent (present in males), hind limb spots absent (present), and gular region and ventrolateral aspect of head lime-green (immaculate). Cnemidophorus jalapensis differs from C. littoralis in having 24–29 ventral rows (30– 38 in C. littoralis), 11–16 femoral pores (28– 36), 200–250 dorsals (168–191), 19–26 scales around tail (25–34), 6–8 ventrals in transverse row (8–10), and gular region and ventrolateral aspect of head and body lime-green (light blue or white). Cnemidophorus jalapensis differs from C. ocellifer in having 11–16 femoral pores (16–28 in C. ocellifer), lateral spots absent (present in most individuals), gular region lime-green (immaculate), ventrolateral aspect of head lime-green (brownish), and ventrolateral aspect of body lime-green (brownish [females] or green [adult males]). Cnemidophorus jalapensis differs from C. parecis in having 11–16 femoral pores (25– 33), 19–26 scales around tail (34–47), 0–2 pairs of chinshields not in contact with infralabials (1–3 in C. parecis), 24–29 ventral rows (29–35), 6–8 ventrals in transverse row (8–10), 4–6 prefemorals (5–12), 8–10 rows of prefemorals (10–14), paravertebral stripes interrupted (absent in C. parecis), gular region lime-green (yellowish), and ventrolateral aspect of body lime-green (brownish [females] or blue [adult males]). Cnemidophorus jalapensis differs from C. abaetensis in having 11–16 femoral pores (21–30 in C. abaetensis, Dias et al., 2002), 24–29 transverse rows of ventrals (29–35), 12–18 fourth finger lamellae (16–21), dorsal aspect of tail brownish (bright blue green to emerald green), smaller body size (maximum SVL 72 mm), dorsal tail stripe absent (bright green dorsal tail stripe), and gular region and ventrolateral aspect of head and body lime-green (immaculate). Cnemidophorus jalapensis differs from C. nativo in having 11–16 femoral pores (22– 26 in C. nativo, Rocha et al., 1997), 24–29 ventral rows (29–32), brownish dorsum (black with a faint middorsal stripe), 6–8 ventrals in a transverse row (8), smaller body size (maximum 69 mm), and gular region and ventrolateral aspect of head lime-green (light blue). |
Comment | Group: this species belongs to the ocellifer group, distinguished by the presence of granules in the supraorbital semicircles, a lower number of femoral pores (less than 40), and the absence of preanal spurs (Rocha et al., 2000, Colli et al., 2003). |
Etymology | named after the region of the type locality, the Jalapão region in northern Cerrado. |
