Range Description

The distribution of C. a. paraguayanus (here referred to as C. cay) is described by Cabrera (1957) as the south of the state of Mato Grosso (now the states of Mato Grosso and Mato do Grosso do Sul) and extreme south-east of Goiás, Brazil, through Paraguay, to south-east Bolivia, to northern Argentina, including the provinces of extreme south-east Jujuy, Salta, Formosa, and Chaco (Mantecon et al. 1984; Brown 1989). In Paraguay, C. cay occurs to the east of the Río Paraguai (Hill 1960; Stallings 1985, 1989). Capuchin monkeys are not found in the chaco region of the Provinces of Formosa and Chaco in northern Argentina. So the distribution of C. cay forms a horseshoe shape, bordering the xerophytic chaco of Argentina, Bolivia, and Paraguay (Brown and Rumiz 1986). In the west, the limits are defined by the Andes in Argentina and Bolivia, and in the east it is confined to eastern Paraguay, east of the Rio Paraguai. Probably its southernmost limit in the east is defined by the confluence of the Rios Paraguai and Paraná, about 27º15’S.
