Population Trend


Major Threats

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.

Conservation Actions

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.
