This species occurs mainly in southern Colombia in the Pacific lowlands and slopes of the Cordillera Occidental in the Departments of Nariño and Valle del Cauca, south to the Río Mira in extreme northern Ecuador. Its altitudinal range is 100-1,600m asl.
Habitat and Ecology
It is a forest inhabitant, occurring from tropical lowland forest to lower cloud forest. The ability of this species to adapt to disturbed habitats is unknown, although it is probably restricted to closed forest. It is closely associated with small streams, and only rarely strays from the immediate vicinity of these; they are not found along larger rivers. It is active at night, sitting on rocks or in rocky crevices, or on very steep cliffs alongside streams. It is presumed to breed by direct development.
It is a very uncommon species.
The major threat is probably habitat loss, due to agricultural development (including plantations, and the planting of illegal crops), logging, and human settlement. Pollution, resulting from the spraying of illegal crops, is also a significant threat.
It is present in several protected areas in Colombia, including Parque Nacional Natural Farallones de Cali.
This species was previously included in the genus Eleutherodactylus (Crawford and Smith 2005).
