This species is found on the Pacific versant of the Sierra Madre del Sur in Guerrero and Oaxaca, and in central Guerrero and south-western Oaxaca in fragmented areas, at elevations of 1,280-2,000m asl.
Habitat and Ecology
It is a stream-breeding amphibian that inhabits cloud forest, close to low streams.
Recent surveys suggest that this formerly common species has declined and is now rare.
The recently recorded declines are probably due to chytridiomycosis, although habitat loss and disturbance due to human activities (agriculture and logging) also represents a major threat to this species.
The range of this species does not include any protected areas, and protection of the original cloud forest habitat is required. Given the apparent risk posed by chytrid, a captive-breeding programme may need to be established.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat, and in the number of mature individuals maybe due to chytridiomycosis, in Guerrero and Oaxaca, Mexico.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
