Atropoides nummifer occiduus is a venomous pitviper subspecies[3] endemic to southern Mexico, Guatemala, and El Salvador.


Adults are usually 35–60 cm (13 3423 58 in) in total length. The largest specimens reported are a male of 74.8 cm (29 12 in) from Baja Verapaz, Guatemala, and a female of 79.5 cm (31 14 in) from Volcán de Agua, Escuintla, Guatemala. The build is very stout, although not so much as that of A. n. mexicanus.[2]

Geographic range[edit]

Found in southern Mexico (southeastern Chiapas), southern and central Guatemala, and western El Salvador.[2] 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.[1]


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).


Regarded as a full species, Atropoides occiduus, by Campbell and Lamar (2004).[2]
