Found at elevations of 800–1,500 m in Mexico on the upper slopes of the Sierra de Los Tuxtlas in southern Veracruz. Also found in eastern Oaxaca, and from northwestern Chiapas to Guatemala. [5] The type locality given is "crest of Cerro Egega, 1100 m, municipality of Catemaco" (Veracruz, Mexico). [1]
This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001). [5] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is stable. Year assessed: 2007. [6]
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.
