Cerrophidion is a genus of pit vipers 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] Five species are recognized as being valid, but no subspecies are. [3]

Description

Species in the genus Cerrophidion grow to a maximum total length (including tail) of 82.2 cm (32.4 in) (for C. godmani), but usually do not exceed 50–55 cm (20–22 in). 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

Cerrophidion species 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]

<i>Bothrops</i> Genus of snakes

Bothrops is a genus of highly venomous pit vipers endemic to the Neotropics. The generic name, Bothrops, is derived from the Greek words βόθρος, bothros, meaning 'pit', and ὄψ, ops, meaning 'eye' or 'face', together an allusion to the heat-sensitive loreal pit organs. Members of this genus are responsible for more human deaths in the Americas than any other group of venomous snakes. Currently, 48 species are recognized.

<i>Bothriechis</i> Genus of snakes

Bothriechis is a genus of pit vipers, commonly called palm vipers or palm-pitvipers found predominantly in Mexico and Central America, although the most common species, B. schlegelii, ranges as far south as Colombia and Peru. All members are relatively slender and arboreal. The name Bothriechis is derived from the Greek words bothros and echis that mean "pit" and "viper" respectively. Ten species and no subspecies are currently generally recognized.

<i>Ophryacus</i> Genus of snakes

Ophryacus is a genus of venomous pit vipers endemic to Mexico.

Currently, three species are recognized and no subspecies.

Porthidium is a genus of venomous pitvipers found in Mexico and southward to northern South America. The name is derived from the Greek word portheo and the suffix -idus, which mean "destroy" and "having the nature of", apparently a reference to the venom. As of August 2016 nine species are recognized as being valid. The snakes of the genus Hypnale in southern India and Sri Lanka look quite similar to those of this genus, possibly an example of convergent evolution.

Gloydius strauchi is a species of venomous pit viper in the subfamily Crotalinae of the family Viperidae. The species is native to western China. It is a small snake with a pattern of four longitudinal stripes, although some older specimens may be a uniform black. G. strauchi may be distinguished from G. monticola by its higher midbody dorsal scale count. This species jointly holds the altitude record for pitvipers together with Crotalus triseriatus of Mexico, both being found even above the tree line at over 4,000 m (13,000 ft). No subspecies were recognized as being valid, until a recent publication re-evaluated the taxonomic statuses of populations of G. strauchi and described the eastern Tibetan populations as a new species.

Bothrops oligolepis is a venomous pitviper species found in Peru and Bolivia.
