This species is known from the Venezuelan states of Aragua, Carabobo, Cojedes, Falcón, Lara, Miranda, Portuguesa, Yaracuy, and the Andean piedmont of Barinas State. It has also recently been reported from Colombia on the Cordillera Central and Cordillera Oriental. It is a mid-altitude species, occurring up to 1,800m asl.
Habitat and Ecology
This is a nocturnal and crepuscular frog living on the floor of semi-deciduous (seasonal) forest in mountain regions of the Venezuelan coastal mountain range and the northernmost portion of the Venezuelan Andes. It is often associated with slow-flowing stream pools where it congregates in large numbers in the breeding season.
It is a common species.
Habitat degradation is a major threat since most of the species' habitat is being converted for coffee and cacao plantations.
Some populations are within national parks in the Venezuelan Coastal range, and the Sierra de Portuguesa (Portuguesa and Lara States). Lower montane forests in the Venezuelan Andes are in need of protection, especially the semi-deciduous forests that have been used for coffee and cacao plantations for centuries.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is not much greater than 20,000 km2, and the extent and quality of its habitat are declining, thus making the species close to qualifying for Vulnerable.
