This species is known only from four localities in the Cordillera Occidental, in the department of Valle del Cauca, Colombia, at elevations of 1,500-2,000m asl.
Habitat and Ecology
It is terrestrial, commonly found in leaf-litter in primary and disturbed forests, but is restricted to moist conditions. Breeding is by direct development.
It is an uncommon species.
This is a large frog with a small population that is very sensitive to human disturbance. All known localities are threatened by the expansion of the city of Cali, in particular due to agriculture and human settlements.
Some populations are inside Yotoco Forest Reserve, which affords some protection to the species' habitat, but there is clearly a need for improved protection of the habitat of this species, particularly given its microhabitat requirements.
