This species is found only on the slopes of Cerro Teótepec, in the Sierra Madre del Sur, in Guerrero, Mexico, at 1,760-2,415m asl.
Habitat and Ecology
This species inhabits pine-oak and bamboo-tree fern forests. It is commonly found associated with cascading mountain streams where it breeds.
This is a rare species. Recent attempts to locate it have been unsuccessful, suggesting a population decline, and it might even be extinct.
It has possibly been impacted by chytridiomycosis. In addition, the transformation of the forests along the transect between Filo de Caballo and Atoyac to open agricultural lands and farmlands is having a detrimental impact on the remaining habitat of this species.
The range of this species does not include any protected areas. While additional survey work is urgently needed to determine whether or not this species is still extant in its natural range, a program to protect the forest areas surrounding the Cerro Teótepec is also recommended. 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 new genus Charadrahyla (Faivovich et al. 2005).
