From the IUCN Red List Species Account:


Range Description

This species occurs at intermediate elevations along the Pacific versant of eastern Chiapas (Unión de Juarez), Mexico to western Guatemala, at elevations of 1,500-1,700m asl.

Habitat and Ecology

This species has been recorded in foothills in premontane tropical forest. It is probably a stream breeder.


This is a rare species throughout its range, and there are no recent records of it in either Mexico or Guatemala, despite searches.

Population Trend


Major Threats

The alteration of the original forested areas by local people has severely impacted the only known habitat for this species. Furthermore, as a montane stream-breeding bufonid, it is possible that the species may be at risk of chytridiomycosis.

Conservation Actions

Conservation of the forested areas along the foothills of the Tacana volcano is necessary to ensure the preservation of this species. Fortunately, some programs of protection and restoration of the forests in the area have been implemented. In view of the severe risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations should be established if chytrid is shown to be a threat.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Mexico and Guatemala.
