Assessor(s): Georgina Santos-Barrera, Luis Canseco-Márquez, Joseph Mendelson III
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because of a projected decline greater than 80% over the next ten years, due to a decline in the quality and extent of the species' habitat, and the effects of chytridiomycosis.

Habitat and Ecology:It is associated with humid cool areas in wet pine-oak-fir cloud forest. Breeding takes place in streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The disturbance and transformation of the species' forest habitat is the major threat, mainly as a result of logging and the continuing expansion of human settlements in the region. Chytridiomycosis might also be a threat, since it is a high-elevation stream-dweller, and declines due to the disease have already been detected amongst other species of this genus.

Conservation Actions [top]

Conservation Actions: Legal protection of the Natural Park in Guerrero is required since it is not in a biosphere reserve and currently lacks any management plan. Further survey work is required to monitor the population status and trends of this species; also, in view of the threat of chytridiomycosis, ex-situ populations might need to be established. This species is protected by Mexican law under the "Special Protection" category (Pr).
