Cerrophidion is a genus of venomous pitvipers that are found in southern Mexico, southward through the highlands of Central America to western Panama.[1] The name is derived from the Spanish word cerro, which means "mountain", and the Greek word ophidion, which means "small snake."[2] Four species are currently recognized and no subspecies.[3]

Description

These snakes grow to a maximum length of 82.2 cm (for C. godmani), but usually do not exceed more than 50-55 cm. The head scalation is highly variable, with some being enlarged, especially in the frontal region. The fact that the prelacunal is not fused with any of the supralabial scales is characteristic for this genus. The rest of the scalation is as follows: 1-7 intersupraoculars, 7-11 supralabials, 8-12 sublabials, 120-150 ventral scales, 22-36 subcaudal scales (undivided) and 17-21 (rarely 23) dorsal scales at midbody.[2]

Geographic range

Found in southern Mexica (in the highlands of Guerrero and southeastern Oaxaca), southward though the highlands of Central America (Guatemala, El Salvador, Honduras, northern Nicaragua and Costa Rica) to western Panama.[1]
