Listed as Endangered because its extent of occurrence (EOO) is 3,484 km2, it occurs in four to five locations, and there is a continuing decline in the quality and extent of its habitat due to illegal crops, cattle grazing, and mining activities.
|Previously published Red List assessments:|
|Range Description:||This species occurs on the western slopes of the Cordillera Occidental in Colombia, in Risaralda, Chocó and Valle del Cauca Departments. It occurs between 600 and 1,280 m Asl (M. Bernal, F. Vargas-Salinas, D. Mejía pers. comm. 2016). Records of this species in Calima, Valle del Cauca need to be confirmed and therefore have not been included in this assessment. The subpopulations from Cauca formerly attributed to this species are now described as Phyllobates terribilis. Its EOO is 3,484 km2 and it is considered to occur in four or five threat-defined locations.|

|Population:||It was formerly considered to be common, but is now an uncommon species and therefore it is inferred that the population trend is decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This diurnal frog lives in the leaf litter, close to streams in tropical moist lowland and premontane forests. It can survive in logged forest, but not in open areas. It breeds continuously throughout the rainy season (March–November). The female lays a clutch of 12–20 eggs in a covered nest in the leaf litter (Halliday 2016). The male guards the eggs and keeps them moist, and, upon hatching he transports the larvae to pools in streams where they continue to develop.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||It is known to be traditionally used by native Colombians, such as the Chocó Indians of the Emberá group living near the headwaters of the Río San Juan, to poison their blow-gun darts (Myers et al. 1978). It occurs in the international pet trade and is a common frog in U.S. hobby shops, but it is easy to breed in captivity. Legal exportation of this species out of Colombia has been banned since 1985.|
|Major Threat(s):||The major threats include habitat loss due to cattle grazing, mining, and pollution from illegal crop-spraying. The chytrid fungus Batrachochytrium dendrobatidis is present within the range of this species; however, no individuals have yet been tested for chytridiomycosis so it remains unclear whether the species is affected.|
It occurs in Tatamá National Park. Decree INDERENA No. 39 of 9 July, 1985, forbids the collection of Phyllobates spp. from the wild in Colombia for breeding (or other) purposes. It is listed on CITES Appendix II.
Further survey work in the southern part of the distribution is needed to establish the limits of the species' range. Additional research on this species' distribution, population trends, ecology, and threats is recommended.
