| Diagnosis | Diagnosis: A slender, medium sized species of Ameivula that can be assigned to the A. ocellifera group due to the presence of a low number of femoral pores (less than 20), enlarged scales in the temporal region (posteriorly to the third subocular), five supraciliary scales, 8 rows of ventral scales, and a brown tail. Furthermore, the new species present a tongue with a forked posterior edge (heard-shaped tongue) and lack a lingual sheath (MZUSP 103266). The new species differs from the other species of the genus (characters in parentheses) by having three supraocular scales (only 2.4% of the specimens of A. confusioniba with three supraoculars, the other species with four or five); circumorbital with an incomplete series of granules that allows contact between frontoparietal and third supraocu- lars (contact absent), the third pair of chinshields being the largest (usually the first pair longer or equal; Fig. 2 A, B, C), fewer lamellae of the fourth finger, mean 5 12.5 (mean . 14.7), and a small foot, where the mean of the relation between foot length and SVL equals 29 (mean . 31; Table 1). In addition, A. cipoensis differs from A. jalapensis by having 17–20 (mean 5 17.7) femoral pores (10–16, mean 5 13.2 in A. jalapensis), 24 –29 (mean 5 27.2) scales around the tail (22–26, mean 5 24), 28–30 (mean 5 29.1) transverse rows of ventral scales (25–27, mean 5 25.7), a medium body size, with maximum SVL = 5 71.3 mm, R 5 68.8 mm (smaller body size, with maximum SVL = 5 54.2 mm, R 5 58 mm), 20.8–23.4 tail length/SVL (22.3–25.8), gular region and ventrolateral aspect of the head and body white (lime- green; Colli et al., 2009), and lower lateral fields with ocelli (ocelli absent). Ameivula cipoensis differs from A. mumbuca by having 21–24 (mean 5 22.5) lamellae in the fourth toe (25– 29, mean 5 26.8), 85–100 (mean 5 92.6) scales around midbody (91–117, mean 5 101), lower lateral fields with ocelli in both males and females (only in males). Ameivula cipoensis differs from A. ocellifera by having 28–30 (mean 5 29.1) transverse rows of ventral scales (26–28, mean 5 27.1 in A. ocellifera), 21–24 (mean 5 22.5) lamellae in the fourth toe (28–31, mean 5 30), 202–225 (mean 5 213.6) dorsal scales (172–188, mean 5 181). Ameivula cipoensis differs from A. confusioniba by having 21–24 (mean 5 22.5) lamellae in the fourth toe (29–35, mean 5 30.4 in A. confusioniba), 202–225 (mean 5 213.6) dorsal scales (188– 211, mean 5 201.6), and bright yellow greenish ocelli on lower lateral fields extending from forelimbs to hindlimbs (only 2–4 small yellow ocelli). Ameivula cipoensis differs from A. nigrigula by having 21–24 (mean 5 22.5) lamellae in the fourth toe (30–32, mean 5 31.3 in A. nigrigula), 25–29 (mean 5 26.7) scales around the tail (27–32, mean 5 30), patch of tibiotarsal spurs absent in males (present), a white throat (dark black), ontogenetic color change absent in males (present). Ameivula cipoensis differs from A. abalosi by having 21–24 (mean 5 22.5) lamellae in the fourth toe (24–30, mean 5 27.3 in A. abalosi), postnasal and prefrontal scales contacting each other (no contact), and by lacking a distinctive patch of tibiotarsal spurs in males (present). Ameivula cipoensis differs from A. nativa by showing bisexual reproduction (parthenogenetic species) and having 17–20 (mean 5 17.7) femoral pores (22–26, mean 5 24 in A. nativa), 21–24 (mean 5 22.5) lamellae in the fourth toe (26– 33, mean 5 31), and by lacking a mid-dorsal stripe (present, with a posteriorly undulating margin). Ameivula cipoensis differs from A. pyrrhogularis by having 12–14 fourth finger lamellae (13–19); 21–24 fourth toe lamellae (24–34); max- imumSVL=571.3mm,R566.8(maximumSVL=5 89 mm, R 5 77.5 mm); and gular region white in males (orange in males; Silva and Ávila-Pires, 2013). Ameivula cipoensis differs from all members of the A. littoralis group (i.e., A. abaetensis, A. cyanura, A. littoralis, and A. venetacauda) by having enlarged scales in the lower temporal region posteriorly to the third subocular (scales subequal), three rows of enlarged scales in the dorsal part of the arm (one row), 5 supraciliars (6–7), 8 longitudinal rows of ventral scales (8–10), 28–30 (mean 5 29.1) transversal ventral rows (29–38), 17–20 (mean 5 17.7) femoral pores (21–45), absence of tibiotarsal spurs in the males (with 1–2 rows of 4–6 spurs), and by having a brown tail (bluish-green). Further- more, it differs from A. littoralis and A. abaetensis by the absence of a mid-dorsal stripe (present in both species) and absence of a stripe in the tail (present in both species). Ameivula cipoensis also differs from A. venetacauda by having lateral ocelli (absent in A. venetacauda). [from ARIAS et al. 2014]. |
