This species is known from Puerto del Gallo, north-central Guerrero, and the Sierra del Sur de Oaxaca, Mexico. The recent record from Oaxaca is probably in error and is currently under taxonomic revision. The type locality in Guerrero is at 2,034m asl.
Habitat and Ecology
It inhabits pine-oak and montane cloud forest remnants, and breeds by direct development.
It is a rare species.
The main threat to this species is deforestation due to logging and the cultivation of crops.
The range of this species does not include any protected areas, and protection of the fragments of cloud forest and pine-oak forests that still remain in the Guerrero area is urgently needed. This species is protected by Mexican law under the "Special Protection" category (Pr).
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 habitat in Guerrero and Oaxaca, Mexico.
This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005).
