This species occurs only in two locations, one on the Pacific slope of the Sierra Madre del Sur, Distrito de Pochutla, Oaxaca, Mexico (the type locality, at 2,160m asl), and one 7.5km south-east of Llano de Guadalupe, in north-west Oaxaca (2,850m asl).
Habitat and Ecology
This species was collected in pine-oak forest. It is believed to breed in small streams.
This species has only been collected twice, once in 1969 and again in 1993. Recent attempts to locate it have been unsuccessful.
A major threat is the loss of pine-oak forest habitat to logging and agriculture. It might also have been impacted by chytridiomycosis.
The range of this species is not within any protected area, and the protection and/or restoration of the original habitat of this species is required. This species is listed as "Threatened" (Amenazada) by the Mexican government. Further survey work is required to determine the population status of this species, and whether or not it survives in the wild; given the likely threat of chytridiomycosis, any surviving individuals might need to form the basis for the establishment of an ex-situ population.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered due to a suspected population decline of greater than 80% over the last ten years due to deforestation and potentially the effects of chytridiomycosis. It has not been seen since 1993 and is now possibly extinct.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
