Atractus trilineatus, commonly known as the three-lined ground snake, is a species of small burrowing colubrid snake, which is endemic to South America.[2]

Geographic range[edit]

It is found in northern South America,[3] including the islands of Trinidad and Tobago.[2]


Adults may attain 225 mm (8 34 in) in total length, including a short tail of 15 mm (12 in). Dorsally, they are brown with three or four darker longitudinal stripes; ventrally they are either uniform white, or have a few brown dots. The smooth dorsal scales are in 15 rows, and the anal plate is entire. Ventrals are 125-150, and subcaudals only 11-19.[4]


They are believed to feed on soft-bodied insects and earthworms.[5]
