Range Description

According to van Roosmalen et al. (2002), Callicebus baptista has a disjunct distribution, occurring in central Brazilian Amazonia, south of the Rio Amazonas, east of the Rio Madeira in the state of Amazonas streching almost as far as the state of Pará, and north of the Paraná do Canumã, Paraná do Urariá, and Paraná do Ramos (van Roosmalen et al. 2002). It was first seen in the wild on the west (left) bank of the Rio Uíra-Curupá, and is believed to have crossed over the Paraná do Ramos west of the town of Parintins forming an enclave population in the lower Rio Uíra-Curupá-Andirá interfluve. Further surveys are rquired in this area to establish the exact range.

M.G.M. van Roosmalen (pers. comm.) has also observed populations of entirely pale yellowish to almost white colour morphs of Callicebus hoffmannsi along the Rio Mamurú, one river further to the east, and classic yellowish-white and gray Callicebus hoffmannsi on both banks of the middle and upper Rio Andirá.
