Porthidium dunni is a species of pit viper in the family Viperidae. The species is endemic to Mexico. There are no recognized subspecies. [4]
The specific name, dunni, is in honor of American herpetologist Emmett Reid Dunn [5] "in appreciation of his work on American snake fauna". [6]
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. [3]
P. dunni is found in southern Mexico in the Pacific lowlands of Oaxaca and western Chiapas. [7]
The type locality given is "the immediate vicinity of the village of Tehuantepec" [Oaxaca, Mexico]. [2]
P. dunni is ovoviviparous. [7]
The species P. dunni is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2007). [1] 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. [8]
Porthidium is a genus of pit vipers found in Mexico and southward to northern South America. The name is derived from the Greek word portheo and the suffix -idus, which mean "destroy" and "having the nature of", apparently a reference to the venom. As of August 2016 nine species are recognized as being valid. The snakes of the genus Hypnale in southern India and Sri Lanka look quite similar to those of this genus, possibly an example of convergent evolution.
Norman Edouard "Kibe" Hartweg was an American herpetologist, Curator of Herpetology for the Museum of Zoology at the University of Michigan, and president of the American Society of Ichthyologists and Herpetologists. He was a specialist in the taxonomy and distribution of turtles, and is honored by having a subspecies of turtle named after him: the western spiny softshell turtle, Apalone spinifera hartwegi. He is also credited with having described several new species, including the Big Bend slider, Trachemys gaigeae, the Oaxacan patchnose snake, Salvadora intermedia, and Dunn's hognose pit viper, Porthidium dunni.
