This species is known from extreme eastern Oaxaca (Chimalapas) and extreme south-western Chiapas, Mexico, and adjacent Guatemala.
Habitat and Ecology
This species only inhabits montane cloud forest from moderate to high elevations in almost pristine environments. It is presumed to breed in streams.
It is not very common.
The major threat is habitat loss due to deforestation and infrastructure development. However, chytridiomycosis is also a potential threat.
The range of this species includes Reserva de la Biósfera El Triunfo. There is a need for close population monitoring, particularly if chytrid is shown to represent a genuine threat. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2 and its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
