This species occurs in the eastern, central and upper Amazon Basin of Brazil, from Cerro Marahuaca in Amazonas state, Venezuela, in the lower Amazonian slopes of the Andes, Amazonas and Putumayo departments, Colombia and Peru, at 0-800m asl. The records in Venezuela might belong to a different, as yet undescribed species, but pending resolution they are included here.
