From the IUCN Red List Species Account:


Range Description

This species occurs in the Soconusco region and slopes of Volcán Tacana, southern Chiapas, Mexico, and adjacent western Guatemala at Volcán Tejumulco, at elevations of 1,500-2,700m asl.

Habitat and Ecology

The primary habitat is montane cloud forests, and it breeds near streams and does so via direct development.


It is uncommon and is known only from few localities.The population in Guatemala is known to be declining, and there have been no records from Mexico since 1997 (recent surveys in Chiapas have not been successful in locating it).

Population Trend


Major Threats

It is likely that this species is declining because of chytridiomycosis, which has heavily impacted some other streamside Craugastor species. Habitat loss is also a threat to the species, particularly in Mexico where the population occurs in a continuously altered forest.

Conservation Actions

It is not found within any protected areas, and protection of the forested areas along the Soconusco region in Mexico is clearly necessary. In view of the threat of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations should be established. This species is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, probably due to chytridiomycosis.

Taxonomic Notes

This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005).
