This species is widespread through the Sierra Madre del Sur of Guerrero and Oaxaca, Mexico.
Habitat and Ecology
This species inhabits conifer forests at intermediate elevations. It breeds in streams.
There are many healthy populations of this species along its range although it is reportedly rare in some parts.
Logging is probably a threat to this species. Tadpoles have been found in southern Mexico with loss of keratinized mouthparts, which suggests that chytridiomycosis might be a threat.
The range of this species does not include any protected areas, and there is a need for improved protection and maintenance of forest habitats in the Sierra Madre del Sur. 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, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Guerrero and Oaxaca, Mexico.
