editP. 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]
Habitat
editReproduction
editP. dunni is ovoviviparous.[7]
Conservation status
editThe 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]
