Metlapilcoatlus occiduus is a venomous pitviper subspecies [4] endemic to southern Mexico, Guatemala, and El Salvador.
Adults are usually 35–60 cm (13+3⁄4–23+5⁄8 in) in total length. The largest specimens reported are a male of 74.8 cm (29+1⁄2 in) from Baja Verapaz, Guatemala, and a female of 79.5 cm (31+1⁄4 in) from Volcán de Agua, Escuintla, Guatemala. The build is very stout, although not so much as that of M. mexicanus . [3]
Found in southern Mexico (southeastern Chiapas), southern and central Guatemala, and western El Salvador. [3] The type locality given is "Saint-Augustín (Guatemala), versant occidentale de la Córdillère. 610 mètres [2,000 ft] d´altitude". Actually, San Augustín is on the southern slope of Volcán Atitlán. [2]
Its habitat includes subtropical wet forest on the Pacific versant from southeastern Chiapas, Mexico to western El Salvador. It also inhabits the pine-oak forest near Guatemala City. It can be found at altitudes varying from 1,000–1,600 m (3,300–5,200 ft).

Metlapilcoatlus is a genus of venomous pit vipers endemic to Mexico and Central America. Six species are currently recognized. The common names suggest they are able to leap at an attacker, but this is likely exaggerated. Common names for the species include jumping pitvipers and jumping vipers.
Bothriechis is a genus of venomous 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.
Ophryacus is a genus of venomous pit vipers endemic to Mexico. The name is derived from the Greek word ophrys, which means "brow", and the Latin word acus, which means "needle", an allusion to the characteristic horn-like scales over the eyes. Currently, three species are recognized and no subspecies.
Cerrophidion is a genus of venomous pitvipers which are endemic to southern Mexico, Central America, and western Panama. The generic name, Cerrophidion, is derived from the Spanish word cerro, which means "mountain", and the Greek word ophidion, which means "small snake". Two species are currently recognized, but 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.
