From the IUCN Red List Species Account:

 

Range Description

This species is known only from the northern slope of the Cerro Pelón, Sierra de Juárez, north-central Oaxaca, Mexico at 2,500-2,700m asl.

Habitat and Ecology

This stream-breeding amphibian seems to occur in rocky streams in cloud forest areas.

Population

This has always been a rare species, but it appears to have gone into serious decline, and has not been recorded since 1984. Recent surveys to locate it have been unsuccessful, and it might now be extinct.

Population Trend

Decreasing

Major Threats

It has disappeared in suitable habitat, probably due to chytridiomycosis. It occurs within an area in Sierra de Juárez, Mexico, which is undergoing a rapid rate of land transformation at present due to logging and agricultural activities.

Conservation Actions

The range of this species is not within any protected area; a plan for the protection and/or restoration of the large forested areas of Sierra de Juárez is urgently required. Survey work is needed to determine the current population status of this species and whether or not it still survives in the wild. In view of the threat of chytridiomycosis, surviving individuals might need to form the basis for the establishment of an ex-situ population.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
