CommentDiagnosis. A slender, medium sized species of Ameivula, distinguished from all other species of the genus by the following combina- tion of characters: (1) 6-7 supralabials; (2) 5- 6 infralabials; (3) 4-5 supraoculars; (4) five supracilaries; (5) 4-6 parietals; (6) 8 longitudinal rows of ventral scales; (7) 27-29 transversal ventral rows; (8) 14-17 femoral pores; (9) 184- 216 dorsal scales; (10) 24-29 scales around tail; (11) 94-102 scales around midbody; (12) 13- 15 fourth finger lamellae; (13) 23-28 fourth toe lamellae; (14) 41-47 gular scales; (15) absence of paravertebral stripes; (16) lateral ocelli extending from hindlimbs to forelimbs.
The new species is assigned to the Ameivula ocellifera group (Arias et al., 2011a) by a low number of femoral pores (less than 20), en- larged scales in the temporal region (posteriorly to the third subocular), five supraciliary scales, 8 rows of ventral scales, and a brownish tail.
