Range Description

Aotus brumbacki is a lowland night monkey, that extends east from the Cordillera Oriental in Colombia between the Ríos Arauca and Guaviare (Hershkovitz 1983; Defler 2003, 2004). The form occurring along the middle and lower reaches of the Meta, Tomo and Vichada and Guaviare has not been ascertained. Based on a specimen collected at Maipures, near the mouth of the Río Tomo on the Río Orinoco, Defler and Bueno (2007) indicated that the night monkeys of eastern central Colombia north of the Río Guaviare may be A. brumbacki, extending the range of this species to the Río Orinoco. Neither Bodini and Pérez-Hernández (1987) nor Linares (1998) give any indication of the occurrence of A. brumbacki in Venezuela, north of the lower Río Arauca.
