From the IUCN Red List Species Account:


Range Description

This species occurs in Carrizal de Bravos, central-western Guerrero, Mexico. It is found from 2,340-2,600m asl.

Habitat and Ecology

It is associated with humid cool areas in wet pine-oak-fir cloud forest. Breeding takes place in streams.


This is a very rare species.

Population Trend


Major Threats

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

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).

Red List Status

Critically Endangered (CR)


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.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
