This species can be found in the Amazon basin, in the Guianas and the upper Amazon Basin in Venezuela (Amazonas and Bolivar states), Colombia, Peru, Bolivia, and western Brazil. A dot-map of distribution in French Guiana is provided in Lescure and Marty (2001). This species has an altitudinal range of sea level to 860m asl.
Habitat and Ecology
It is in an arboreal species found in primary and secondary forests (often along rivers) and border of forest, usually at heights of up to 1.5m. It is associated with savannahs in Suriname. For reproduction, the species employs temporary ponds.
This species can be considered as uncommon to common. It is not frequent in French Guiana (Lescure and Marty, 2001).
Although there are no major threats to this species, it is threatened locally in Venezuela by illegal mining, and water pollution from the mining is a threat to the species' habitat.
Some populations are within protected areas.
A taxonomic revision of this species is needed. We follow Jungfer and Hödl (2002) in considering Osteocephalus ayarzaguenai Gorzula and Señaris, 1997 "1996", to be a synonym of O. leprieurii.
