Pseustes sulphureus, commonly known as the yellow-bellied puffing snake, is a species of snake in the family Colubridae. The species is endemic to South America.


P. sulphureus is a large snake, which can grow up to 3 metres (9.8 ft) in total length (including tail).[2]

Geographic range[edit]

P. sulphureus is found in northern South America and Trinidad and Tobago.[2]


Adults of P. sulphureus feed on small mammals and birds, while juveniles feed on lizards, mice and rats.[2]


Two subspecies are recognized as being valid, including the nominotypical subspecies.[1]

Nota bene: A trinomial authority in parentheses indicates that the subspecies was original described in a genus other than Pseustes.
