This species is known only from the Sierra Madre del Sur de Guerrero, in Omiltemi and Puerto del Gallo, Mexico, at elevations from 1,985-2,520m asl.
Habitat and Ecology
It inhabits high-elevation cloud and pine-oak forest, in association with streams. Its breeding biology is unknown, but it might take place in streams.
This is a rare species.
Degradation and destruction of the forest patches in Guerrero due to smallholder farming activities and logging is a major threat to this species. Chytridiomycosis may also be a threat, since it occurs at high elevations (and presumably breeds in streams), and declines due to the disease have already been detected amongst other species of this genus.
The range of this species does not include any protected areas, and effective formal protection of the Omiltemi State Ecological Park is needed; the Puerto del Gallo also requires urgent protection. Further survey work is needed to better understand the population status of this species, and whether chytrid poses a threat. This species is listed as "Threatened" (Amenazada) by the Mexican government.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
