This species occurs on the Pacific slopes of the Cordillera Occidental in Colombia, in Antioquia, Chocó, Cauca, Valle del Cauca, Nariño and Risaralda, and Quindío Departments, south to Cotopaxi Province in adjacent Ecuador. It is also known from the eastern slopes of the Cordillera Central in the Department of Caldas (Ruiz-Carranza and Lynch 1998), Colombia. It has been recorded between 1,780–2,650 m asl. It is a species complex (M. Rada pers. comm. 2016).
Habitat and Ecology
This species occurs on vegetation next to streams in montane forests, and is perhaps a little more arboreal than some other related species. It is not found in degraded habitats, but does occur in selectively logged forest. It breeds in streams, with the eggs laid on leaves overhanging the water.
It is uncommon to locally common throughout its range. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing. The population is not severely fragmented.
Localized threats includes habitat loss as a result of deforestation for agricultural development (including the planting of illegal crops), logging, and human settlement. Other threats include the introduction of alien predatory fish, and pollution resulting from the spraying of illegal crops. Specimens of this species have tested positive for Bd, although it is unknown whether chytridiomycosis is a threat.
This species occurs in several protected areas in Colombia, while in Ecuador its range overlaps with Reserva Ecológica Los Illinizas.
Further research in taxonomy, population trends, ecology and distribution are recommended for the species.
Red List Status
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and presumed large population.
This is a species complex (D.F. Cisneros-Heredia pers. comm.)
