Metlapilcoatlus occiduus is a pit viper 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 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. The genus name comes from the Nahuatl name metlapilcohuatl, which means of the oblong grindstone held in the hand when grinding corn—alluding to the snake's short, stocky body.
Loxocemus bicolor, the sole member of the monotypic family Loxocemidae and commonly known as the Mexican python, Mexican burrowing python and Mexican burrowing snake, is a species of python-like snake found in Mexico and Central America. No subspecies are currently recognized. Analyses of DNA show that Loxocemus is most closely related to the true pythons and the sunbeam 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.

Ten species and no subspecies are currently generally recognized.
