This species occurs on both versants from south-eastern Chiapas, Mexico, to east-central Honduras. Its altitudinal range is 950-2,600 m asl.
Habitat and Ecology
This stream-breeding species inhabits cloud forests and premontane and lower montane forest. It is associated with cascading mountain streams.
It is still relatively common in Honduras, but, while formerly common, it is now uncommon in Guatemala and El Salvador. It has not been recorded in Mexico since 1944, and recent surveys to locate it have been unsuccessful.
Although it tolerates moderate habitat destruction, loss of original forest cover affects the microhabitat of this species. In Honduras, tadpoles have been found with deformed mouthparts, indicating chytridiomycosis. This is probably the explanation for the observed declines in the species in recent years.
There is protection of the cloud forests in southern Mexico and it occurs in several parks in Honduras, one in Guatemala, and one in El Salvador. However, given the threat of chytridiomycosis, a captive-breeding programme might need to be established.
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.
