This species occurs in Pacific lowlands and foothills from extreme eastern Oaxaca, east of the plains of Tehuantepec, Mexico, through Guatemala southward to central El Salvador. Another population occurs at the Cintalapa Valley in southwestern Chiapas (0-700m asl). It probably occurs more widely than current records suggest, especially in areas between known sites.
Habitat and Ecology
It occurs in sub humid and humid lowlands and foothills. Populations persist in cutover forests and low scrubby forest. Not found in primary forest. It breeds in small temporary and permanent ponds.
It is common in Guatemala and El Salvador and abundant in Chiapas.
Water pollution is a localised threat.
It occurs in no protected areas in Guatemala and in El Imposible National Park in El Salvador. It does not require protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably not much greater than 20,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining 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 Dendropsophus (Faivovich, et al., 2005).
