Range DescriptionCebus kaapori was described from the eastern Amazon in the state of Maranhão and eastern part of the state of Pará in 1992. The distribution of this form is now quite well known, occurring east of the lower Rio Tocantins to the right bank of the Rio Grajaú in Maranhão where it entres the Zona dos Cocais (Queiroz 1992; Ferrari and Queiroz 1994; Ferrari and Souza Jr 1994; Ferrari and Lopes 1996; Silva, Jr. and Cerqueira 1998; Carvalho, Jr. et al. 1999; Cunha et al. 2007). Although possibly extending as far east as the Mearim-Itapecuru interfluvium in the past, Silva Jr and Cerqueira (1998) concluded that it can be "considered practically absent from the right bank of the Rio Grajaú, eastwards".
