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.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Exerodonta (Faivovich, et al., 2005).
