From the IUCN Red List Species Account:


Range Description

This species is found only on the Pacific slopes of the Sierra Madre del Sur in Guerrero and Oaxaca, Mexico. It probably occurs more widely, especially in intervening areas between currently known sites. It occurs at elevations of 900 and 2,000m asl.

Habitat and Ecology

It inhabits cloud forest and pine-oak forest, and is almost exclusively found in forest streams and the surrounding vegetation. Animals seek refuge in bromeliads during the dry season. Breeding takes place in streams.


This is a common species.

Population Trend


Major Threats

The major threat is habitat loss and disturbance due to expanding agriculture (crops and livestock), logging, and human settlement. Tadpoles have been found in southern Mexico with loss of keratinized mouthparts, which suggests that chytridiomycosis might be a threat.

Conservation Actions

The range of this species does not include any protected areas, and there is a need for improved protection, and/or restoration, of pine-oak forests at sites where this species is known to occur. Close population monitoring is required, especially given the potential threat of chytridiomycosis. It is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Vulnerable (VU)


Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Guerrero and Oaxaca, Mexico.

Taxonomic Notes

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