| Diagnosis | Diagnosis: Chalcides ragazzii is a large, pentadactyl species with unexpanded or slightly expanded vertebral scales, a long tail, a vertebral pale brown or brown stripe with lateral, thin dark brown borders that spans the vertebrals and medial half of the paravertebrals, a cream stripe on the lateral sides of the dorsum, and an irregular dark brown stripe on the flanks; the dorsum, flanks, and tail are extensively to slightly covered with dark brown spots and white ocelli. Chalcides ragazzii is distinguished from C. armitagei by the possession of pentadactyl limbs (tridactyl in C. armitagei), six supralabials (5 in C. armitagei), six infralabials (4 in C. armitagei), one postnasal (absent in C. armitagei), 68–80 ventrals (94–96 in C. armitagei), and 33–39 presacral vertebrae (50–51 in C. armitagei) (Caputo et al., 1995). Chalcides ragazzii is distinguished from C. pulchellus and C. thierryi by having a vertebral pale brown or brown stripe with lateral, thin dark brown borders that spans the vertebrals and medial half of the paravertebrals, a cream stripe on the lateral sides of the dorsum, and an irregular dark brown stripe on the flanks (no stripes in C. pulchellus and C. thierryi), numerous brown spots with white ocelli on the body (no white ocelli in C. pulchellus and C. thierryi), and usually unexpanded or slightly expanded vertebrals (always extensively expanded vertebrals in C. pulchellus and C. thierryi). Differences among populations of C. bottegi, C. ocellatus and C. ragazziii are shown in Table 1. Chalcides ragazzii is distinguished from C. ocellatus by having a vertebral pale brown or brown stripe with lateral, thin dark brown borders that spans the vertebrals and medial half of the paravertebrals, a cream stripe on the lateral sides of the dorsum, and an irregular dark brown stripe on the flanks (no stripes or vertebral stripe spanning vertebrals, paravertebrals, and dorsals lateral to paravertebrals in C. ocellatus), and 22–26 scale rows around midbody (26–32 in C. ocellatus). Chalcides ragazzii is distinguished from C. bottegi by having a vertebral pale brown or brown stripe bordered on each side by a thin, dark brown stripe (pale brown vertebral stripe with brown borders in C. ragazzii; Fig. 7), usually unexpanded or slightly expanded vertebrals (always extensively expanded vertebrals in C. bottegi), 68–80 ventrals (81–92 in C. bottegi), and 33–39 presacral vertebrae (41–43 in C. bottegi) [from GREENBAUM et al. 2006.] |
