This species is known from the Pacific lowlands of Colombia in the Departments of Antioquia, Cauca, Chocó, Risaralda and Valle del Cauca, between 680–1,600 m Asl. Records from northwestern Ecuador were in error (Mueses-Cisneros 2009).
Habitat and Ecology
It lives on the ground in leaf litter close to water sources, in lowland tropical moist forest. All records of this species are from mature forest. There is no information on its breeding biology, although reproduction is presumably by larval development in water.
It is a rare species. There have been no records since those listed in Mueses-Cisneros (2009), despite regular surveys in the Valle del Cauca portion of the range. The population is not considered severely fragmented. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The major threats are deforestation for agricultural development (including the cultivation of illegal crops), logging, mining, and pollution resulting from the spraying of illegal crops.
Its range overlaps with Parque Nacional Natural Farallones de Cali and Parque Nacional Natural Munchique. It may occur also in some regionally protected areas.
More information is needed on this species' distribution, population status, natural history, and threats. There is a need for monitoring the population status of this species given the threats of habitat loss due to agriculture, logging and pollution.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population and its occurrence in two large protected areas. However, the species is apparently rare and more research is required to determine the population size and trends.
