This species occurs on the Pacific slopes of central Guerrero and eastern central Oaxaca, southward through the isthmus of Tehuantepec to northwestern Chiapas, Mexico. It is also found on the slopes of the Chiapan highlands, mainly in the Río Grijalva drainage, Mexico.
Habitat and Ecology
This species inhabits sub-humid oak and pine forest. It is commonly found in arboreal bromeliads. It is a stream-breeding amphibian.
This is a common species.
Transformation or disturbance of the original forest habitat of the species is a major threat.
The range of this species includes Reserva de la Biósfera La Sepultura. Protection of the remaining forest areas in southern Mexico is important. A declaration of the Chimalapas region as a biosphere reserve is urgently needed.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Exerodonta (Faivovich, et al., 2005).
