This species is known only from the Sierra de los Cuchumatanes and the central and southern highlands of Guatemala at an altitudinal range of 2,400-3,500m asl.
Habitat and Ecology
It is a stream-breeding amphibian, living in fir forest, pine-cypress forest, and montane grasslands. It is not known whether or not it can survive in lightly degraded habitats.
There is no information on the population status of this species.
The main threat is habitat destruction due to expanding agriculture and human settlement, and extraction of wood. Chytridiomycosis is a potential threat to this species, as it is a high-elevation stream dweller, and declines due to the disease have already been detected among congeners.
It is not known from any protected areas. However, the range includes the proposed Parque Nacional Cuchumatanes as well as the slopes of the southern Guatemalan volcanoes, which are also proposed for protection. Further survey work is needed to determine the population status of this species, and whether chytrid is a threat.
Red List Status
Listed as Endangered because its Area of Occupancy is probably less than 500km2, its distribution is severely fragmented, and the extent of its habitat in Guatemala is declining.
The form occurring in El Salvador and Honduras is considered a separate species, Plectrohyla psiloderma (McCranie and Wilson 1999a).
