This species is known from two disjunct populations: one in San Vicente de Benitez, in the Sierra Madre del Sur, Guerrero, and the other in San Gabriel Mixtepec, Oaxaca, also in the Sierra Madre del Sur, south-western Mexico. It is found at elevations of 750-1,080m asl in Guerrero, and at elevations of 580-1,530m asl in Oaxaca. It might occur more widely.
Habitat and Ecology
This species only inhabits montane forest at moderate elevations. It breeds in temporary streams.
This species is not common. Recent surveys suggest that it has undergone a decline in numbers.
The destruction and degradation of the original forest cover (mainly due to logging) in Guerrero, is the major threat to this species, and most of the localities where the species occurs have been severely impacted by human activities. Recently documented declines might be due to chytridiomycosis.
The range of this species is not within any protected areas, and there is a need for improved habitat protection at sites where this species is known to occur. The Government of Mexico considers it "Threatened" (Amenazada). Close population monitoring is required, especially given the potential threat of chytridiomycosis.
Red List Status
Listed as Vulnerable because its extent of occurrence is less than 20,000km2, its distribution is severely fragmented, and a continuing decline in the extent and quality of its habitat in Guerrero and Oaxaca, Mexico.
This species was previously included in the genus Hyla but has recently been moved to the resurrected genus Exerodonta (Faivovich et al. 2005).
