Bothrocophias is a genus of pit vipers in the subfamily Crotalinae of the family Viperidae, known by the common name toadheaded pit vipers. The genus is endemic to South America.
Taxonomy
Bothrocophias is a relatively recently identified genus that consists of four to nine species, most of which were traditionally placed in Bothrops.
Oviparity
Recent evidence published by Campbell and Lamar (1989, 2004) suggests that Bothrocophias colombianus may lay eggs rather than give birth to live young. This would make it almost unique among New World pitvipers (but not Asian species). The only other American pitvipers known to lay eggs are the four species of bushmaster (Lachesis).

The following nine species are recognized as being valid.
