This species occurs in the lowlands of western Colombia from 0-900m asl, in the departments of Valle del Cauca, Choco, Risaralda, and Antioquia, and it probably occurs a little more widely. Records from Ecuador are in error.
Habitat and Ecology
It appears to be restricted to primary and secondary forest, and is not found in open areas. It lives on fallen leaves on the ground and on very low herbaceous vegetation. It is presumed to breed by direct development, but the site of egg deposition is not known.
It is an uncommon species.
The major threats are likely to be deforestation for the creation of plantations, cultivation of illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It occurs in Parque Nacional de Las Orquídeas.
