This species is known from the Amazon basin from southern Colombia, Ecuador through Brazil to the Guianas and northeastern Brazil at elevations up to 700m asl. There is a recent record from the Orinoco Delta in Venezuela, in Delta Amacuro state, and a record (but no specimen) in Santa María de Erebato, in estado Bolívar. A record from San Jacinto, northern Departamento Loreto, Peru might be in error.
Habitat and Ecology
Its habitat is lowland tropical rainforest. At Santa Cecilia, Ecuador, specimens have been found on low vegetation in primary forest or at the edge of forest at night (Duellman, 1978). Probably reproduces in small permanent streams.
Apparently uncommon to rare throughout much of the range.
Habitat destruction and degradation might threaten some local populations, but overall this species is not significantly threatened.
Protected under the figure of a Biosphere Reserve in Venezuela. In Ecuador, its geographic range overlaps with Reserva de Producción Faunística Cuyabeno, Parque Nacional Yasuní, and Reserva Biológica Limoncocha.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was resurrected from the synonymy of Osteocephalus buckleyi by Duellman and Mendelson III (1995). However, its taxonomy is still unclear.
