Porthidium dunni is a species of venomous pitviper in the family Viperidae. The species is endemic to Mexico. There are no recognized subspecies.[3]

Etymology[]

The specific name, dunni, is in honor of American herpetologist Emmett Reid Dunn[4] "in appreciation of his work on American snake fauna".[5]

Description[]

Adults of P. dunni are usually 30–40 cm (11+3⁄4–15+3⁄4 in) in total length (including tail), with a maximum of 57 cm (22+1⁄2 in). A moderately stout and terrestrial species, the tip of the snout is moderately elevated.[2]

Geographic range[]

Porthidium dunni is found in southern Mexico in the Pacific lowlands of Oaxaca and western Chiapas.

The type locality given is "the immediate vicinity of the village of Tehuantepec" [Oaxaca, Mexico].[1]

Conservation status[]

The species P. dunni is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[6] 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.[7]
