Common names: Montane pitvipers.[2]

Cerrophidion is a genus of venomous pitvipers which are endemic to southern Mexico, Central America, and western Panama.[1] The generic name, Cerrophidion, 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, but no subspecies.[3]

Description

These snakes grow to a maximum total length of 82.2 cm (32 14 in) (for C. godmani), but usually do not exceed 50–55 in (1,270–1,397 mm). The head scalation is highly variable, with some scales 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 rows (rarely 23) of dorsal scales at midbody.[2]

Geographic range

Snakes of this genus are found in southern Mexico (in the highlands of the Mexican states 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]
