Distribution and Natural History of the Ecuadorian Snake Dipsas andiana (Boulenger, 1896) (Colubridae: Dipsadinae) with Considerations on Its Conservation Status

Diego F. Cisneros-Heredia


The distribution and natural history of Dipsas andiana (Boulenger, 1986), a little-known snake endemic to Ecuador, are revised, and new records are presented that extend its geographical and altitudinal range. A conservation status assessment indicates that D. andiana would classify for the IUCN category «Near Threatened (NT)». The ecological distribution of the species is apparently related with seasonal forests of the West Ecuadorian zone, a recently recognized biogeographic area between the very humid Choco and the dry Tumbesian zone.
