This species is known from western Guyana and south-eastern Venezuela at between 100 and 1,700m asl. It probably ranges more widely than is currently known.
Habitat and Ecology
It inhabits cloud forests, seasonally dry forests, and marshland areas. The females guard the eggs, which are laid terrestrially under cover, such as rocks. The larvae presumably develop in streams. Its ability to adapt to secondary habitats is not known.
The population status of this species is unknown. It is currently known only from four specimens (Marvalee Wake pers. comm.).
It occurs in an area of very limited human impact, and it is therefore unlikely to be significantly threatened.
It occurs in the Canaima National Park, Venezuela.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
The species is sometimes incorrectly cited as Epicrionops nigrus. The taxonomy of the genus is in need of revision (M. Wilkinson pers. comm.).
