Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Panama.

Geographic Range [top]

Range Description: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.

Population [top]

Population: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.).
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a terrestrial species of tropical lowland forest. Breeding and larval development takes place in forest streams.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): 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.

Conservation Actions [top]

Conservation Actions: 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.
