Atractus is a genus of colubrid ground snakes in the Dipsadinae subfamily. The genus includes more than 140 distinct species.[2]

Geographic range[edit]

Snakes of the genus Atractus are endemic to Central and South America.

Description[edit]

This snake's maxilla is short, with 8–12 teeth; the maxillary and mandibular teeth decrease in size posteriorly. The head is not distinct from the neck; the eyes are small, with round or subelliptic pupils, and the nostril is between two nasal scales; the preocular is usually absent, and the loreal and prefrontal scales enter the orbit. Its body is cylindrical; the dorsal scales are smooth, without pits, in 15 or 17 rows; the ventral scales are rounded. The tail can be either short or rather long; its subcaudals are paired.[1]
