Distribution. Amazon Basin of the upper Orinoco and Casiquiare rivers of extreme E Colombia and S Venezuela; it might occur in adjacent N Brazil.
Distribution. Amazon Basin in E Peru (S of the Rio Maranon), NW Bolivia, and W Brazil, largely S of the Amazon River and E to beyond the Rio Purus, but extending N of the Amazon River in the Imeri region W of the lower Rio Negro. in Echimyidae
Distribution. Amazon Basin in E Peru (S of the Rio Maranon), NW Bolivia, and W Brazil, largely S of the Amazon River and E to beyond the Rio Purus, but extending N of the Amazon River in the Imeri region W of the lower Rio Negro.
Distribution. Central Amazon Basin of Brazil (Amazonas and Para states), from the left bank of the lower Rio Negro to the mouth of the Rio Pitinga N of the Amazon River axis, and from the lower Rio Madeira to lower Rio Tapajos on the S side of the main Amazon trunk. in Echimyidae

Distribution. Brazilian Amazon, S of the Rio Amazonas, between the Tapajos/Juruena system and the Tocantins/Araguaia river system to the E, in the Brazilian states of Para and Mato Grosso; the exact S limit ofits distribution is unclear, but it seems likely that it coincides with the transition between the Amazon rainforest and the cerrado savannas of C Brazil; this ecotone encompasses headwaters of the Xingu and Tapajos river systems in N Mato Grosso. Vieira's Titi (C. vieirai) is also known to occur in this region, but there are too few records to confirm whether their distributions intergrade, or in fact where the exact limits of their distributions are. One recent study also found that the Red-bellied Titi may be absent from or present at extremely low densities in large areas of the Tocantins-Xingu interfluvium. Given the overall lack of records, while it is clear that the Red-bellied Titi occurs over a vast area of the SE Amazon Basin, the exact limits of its distribution within this area remain unclear. in Phitheciidae
