This species is known only from the Sierra de Santa Cruz, eastern Guatemala, from 366-1,150m, though it might occur a little more widely.
Habitat and Ecology
It inhabits undisturbed subtropical moist forest and is found near, and breeds in, streams.
It is a common species within its range.
The major threats to this species include habitat loss due to expanding agriculture, wood extraction, and human settlement, and water pollution. Chytridiomycosis is also a potential threat, and declines due to the disease have already been detected amongst other species of this genus in Guatemala (Mendelson et al. 2004).
This species has not been found in any protected area, though one has been proposed within its range. In view of the severe risk of chytridiomycosis, the status of this species should be closely monitored, and ex-situ populations might need to be established.
