This species occurs on the Pacific slopes of the Sierra Madre del Sur de Guerrero, central Guerrero, Mexico, at elevations from 700-950m asl.
Habitat and Ecology
It inhabits pine-oak forest and tropical deciduous forest. It is often found on low vegetation, under logs, rocks and vegetation along streams where it breeds.
It is not a common species.
Habitat loss as a result of smallholder farming activities and logging is the main threat to this species. A larva has been found with keratinised mouthparts, indicative of chytridiomycosis.
The range of this species does not include any protected areas, and protection and restoration of forested areas in Guerrero is urgently needed. Further research and survey work is needed to determine the extent to which chytrid poses a threat; there may beed a need to establish a captive assurance colony of this species.
