Range Description

Aotus zonalis occurs in the lowlands of Panama and the Chocó region of Colombia, extending south, west of the Andes, to the Río Raposo just south of Buenaventura, and including the Urabá region and eastward to the Ro Sinú, and possibly including the upper San Jorge valley to the region of Puerto Valdivia in northern Antioquia (Hall 1981). The range limits with A. griseimembra are not known. Its occurrence in Costa Rica is possible, but not documented (Timm 1988; Timm et al. 1989).

Defler and Bueno (2007) described A. jorgehernandezi from a specimen in captivity in Quindío Department, Colombia, said to be from the Parque de los Nevados on the border between Quindío and Riseralda. This locality is within the range currently considered to be that of A. zonalis.
