Bothrocophias is a genus of venomous snakes in the subfamily Crotalinae of the family Viperidae, known by the common name toadheaded pit vipers.[1] The genus is endemic to northern South America.[2]

Taxonomy

Bothrocophias is a relatively recently identified genus that consists of four[3] to seven[2] 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).
Species

The following seven species are recognized as being valid.[2]

Bothrocophias andianus (Amaral, 1923) – Bolivia and Peru
Bothrocophias campbelli (Freire-Lascano, 1991) – Ecuador
Bothrocophias colombianus (Rendahl & Vestergren, 1940) – Colombia
Bothrocophias hyoprora (Amaral, 1935) – Ecuador, Colombia, Brazil, Peru, and Bolivia
Bothrocophias lojanus (Parker, 1930) – Ecuador, Peru
Bothrocophias microphthalmus (Cope, 1876) – Ecuador, Peru, Bolivia, Colombia and Brazil
Bothrocophias myersi (Gutberlet & Campbell, 2001) – Colombia

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Bothrocophias.
