Identification. These snakes have a thin neck and a distinct head, and the eyes have vertically elliptical pupils. A thick nuchal band extending posterior from the parietal scales is also characteristic. The dorsal pattern consists of brown blotches on a tan ground color and the venter is unmarked. The dorsal scales are smooth and in 17–25 rows at midbody, which reduce to 11–19 rows posteriorly. The vertebral row of dorsal scales is not enlarged. There are 1–4, usually 2, preocular and postocular scales. Su- pralabials range from 7–9, with 8 most frequent, and infralabials are 8–12 with 10 the modal number (Torres- Carvajal et al. 2020). There are 151–204 ventrals and 54– 102 subcaudals.

Habitat. These snakes have been found in primary and secondary forest as well as around and inside buildings. QCAZ 11989 was found under sheet metal on a wood pile and contained the hindlimbs of a frog, probably Leptodactylus , which was swallowed headfirst.
