This species can be found in the Orinoco Basin of Venezuela and Colombia and in the Amazon Basin of Ecuador, Brazil, Peru, Bolivia, Colombia, Venezuela and the Guianas. It also occurs in gallery forest within the Cerrado of Mato Grosso and Maranhão, Brazil. An old record from Caracas, again cited in Barrio (1999) was considered to be erroneous by Trueb and Duellman (1971). Its altitudinal range is up to 1,250m asl.
Habitat and Ecology
This species is a nocturnal frog found in primary and secondary tropical rainforest as well as gallery forest in Cerrado. Individuals perch on trunks in the forest (up to a height of 40m), or sit at the banks of ponds. Also found at the border of forest. The species reproduces in temporary ponds or watercourses (including water-filled tire tracks) in the forest or at the border where it lays eggs. Tadpoles live in the water. Newly metamorphosed individuals are associated with temporary ponds (Neckel-Oliveira, 2007).
This species is abundant.
Habitat loss/clear cutting are major threats.
The range of this species overlaps with several protected areas.
The call variation of this nominal species might conceal a number of cryptic species.
