Cerrophidion barbouri is a venomous pitviper species found in Mexico. No subspecies are currently recognized.^[4]

Description

Adults generally grow to 30-40 cm in length, with a maximum of 51.0 cm. Terrestrial and moderately stout.^[2]

The color pattern consists of a blackish ground color overlaid with a vague dorsal zig-zag stripe that extends down the flanks, which makes it look like a series of triangular markings. The skin between the scales is rust-colored, as are the sides of the head.^[3]

Geographic range

Found in the highlands of the Sierra Madre del Sur in the state of Guerrero, Mexico. The type locality given is "Omilteme [or Omiltemi], Guerrero, Mexico."^[1]

Habitat

Mountain areas at some 9,000 feet (2.74 km) elevation in rocky pine forests and clearings with bunch grass.^[3]

Conservation status

This species is classified as Endangered (EN) on the IUCN Red List of Threatened Species with the following criteria: B1ab(iii) (v3.1, 2001).^[5] A species is listed as such when the best available evidence indicates that the geographic range, in the form of extent of occurrence, is estimated to be less than 5000 km², estimates indicate the population is severely fragmented or known to exist at no more than five locations, and a continuing decline has been observed, inferred or projected in the area, extent and/or quality of habitat. It is therefore considered to be facing a very high risk of extinction in the wild. The population trend is down. Year assessed: 2007.^[6]
