This species is endemic to the eastern Atlantic versant of central Panama, although it is believed to occur much more widely. It is a low-altitude species, occurring at 10-730m asl.
Habitat and Ecology
This is a terrestrial species of tropical lowland forest. Breeding and larval development takes place in forest streams.
This species is reasonably common at a number of localities, and there is little evidence of a decline. However, at Filo de Santa Rita, Provincia de Colón, while relatively abundant in October 2000, only one individual was seen in December 2002 (R. Ibáñez pers. obs.).
The deforestation of habitat for agricultural use and general infrastructure development, as well as water pollution and stream sedimentation, are the main threats to this species. A number of congeners have recently disappeared over much of their range due to the effects of chytrid, although this species probably occurs below the altitude at which chytridiomycosis is prevalent.
The species has been recorded from Parque Nacional Chagres, but expanded habitat protection is recommended. Further survey work is needed to establish the limits of the species' range, and close monitoring of existing populations is necessary.
