This species is known from Parque Nacional Celaque, Montaña Celaque, in the department of De Lempira, western Honduras, and from El Pital in northern El Salvador near the Honduran border. It might occur in Parque Nacional Pital in Honduras (on the Salvadorian border), where larvae thought to belong to this species have been found. Its altitudinal range is from 2,450-2,530m asl.
Habitat and Ecology
It lives on low vegetation and boulders along pristine streams in lower montane moist forest. It breeds in streams, and is not found in disturbed habitats.
It is moderately common in Honduras; there are no recent records in El Salvador.
The main threat is habitat loss, mainly due to agricultural encroachment and wood extraction. Pollution from pesticides is also suspected to be a problem. Chytridiomycosis is a potential future threat, given the impact that it has had on some other high-elevation stream-breeding members of this genus in Central America.
It occurs in Parque Nacional Celaque, and possibly also Parque Nacional Pital, both in Honduras; the Salvadorian population is not protected. Further survey work is needed to determine the status of this species in the Salvadorian part of the range.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat in Guatemala and El Salvador.
