This species is known from Sierra de Juárez and Sierra Mixe, north-central Oaxaca, Mexico. A specimen has also been collected from Los Tuxtlas, Veracruz, Mexico, but this record is in doubt. It probably occurs more widely than records suggest. It occurs at elevations of 680-2,256m asl.
Habitat and Ecology
It inhabits mesic cloud forest, and is commonly found in or near streams and low vegetation, and presumably breeds in streams.
This is a common species.
The high rate of disturbance of the cloud forest is the main threat to this species. Tadpoles have been found in southern Mexico with loss of keratinised mouthparts, suggesting that chytridiomycosis might be involved.
The range of this species does not include any protected areas, and urgent protection of the forests along the Sierra de Juárez and Sierra Mixe is required. The species is in need of close population monitoring, particularly if chytrid is shown to be a genuine threat.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Oaxaca and Veracruz, Mexico.
This species was previously included in the genus Hyla, but has recently been moved to the new genus Charadrahyla (Faivovich et al. 2005).
