This species occurs in the Pacific lowlands and the lower slopes of the Cordillera Occidental in Colombia, from Serranía de Baudó south to northwestern Ecuador. It occurs from sea level to 1,100m asl.
Habitat and Ecology
It is a species of lowland and submontane forest, not occurring in degraded habitats. It lives mainly along clearwater, gravely streams flowing through swampy moist rainforest. It is commonly found along small, sluggish streams at night, usually on the ground or on rocks beside or in the stream, or sitting in shallow water on gravel, silt, or submerged leaf-litter. It is presumed to breed by direct development.
It is an uncommon to moderately common species.
The major threats are likely to be deforestation for agricultural development, plantations, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It occurs in several protected areas in Colombia, and in the Reserva Ecológica Cotacachi-Cayapas in Ecuador.
This species was previously within the genus Eleutherodactylus (Crawford and Smith, 2005).
