This species ranges widely in northern and central Brazilian Amazônia, through the Guianas, to southeastern Venezuela (the only known record from this country coming from Bolívar state, east slopes of Cerro Santa Rosa, in the Serranía del Supamo), and southeastern Colombia. A dot-map of its distribution in French Guiana provided in Lescure and Marty (2001). It occurs at low elevations at 100-700m asl.
Habitat and Ecology
It lives under leaf-litter and in holes in the ground in humid tropical forests at low elevations. It lays large, terrestrial eggs, which develop into non-feeding tadpoles on the ground, and which do not develop in water. It is not known from degraded habitats.
It is a rare frog in collections and its range is poorly documented. However, it can be locally common in places.
It is probably not seriously threatened, but local populations might be impacted by fire and clear cutting.
It occurs in several protected areas, for example Kaieteur and Mabura Hill Forest Reserve (Guyana), La Neblina (Venezuela), and several in Brazil, Suriname and French Guiana.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
