This species is known from the Pacific lowlands of Colombia in Choco Department, and from two localities in north-western Ecuador (in Esmeraldas Province), and is presumed to exist in between these two areas. It occurs between 10 and 500m asl.
Habitat and Ecology
It lives on the ground in leaf-litter close to water sources, in lowland tropical moist forest. All records of this species come from mature forest. There is no information on its breeding biology, although reproduction is presumably by larval development in water.
It is a rare species, and there have been no records of this species in Ecuador since 1984.
The major threats are deforestation for agricultural development (including the cultivation of illegal crops), logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It has been found in a few protected areas in Colombia.
