Geographic Range [top]

Range Description: Saguinus imperator imperator Bolivia, Brazil, Peru
Southwestern Amazon, east of the upper Rio Purus, between the Purus and the Rio Acre (Hershkovitz, 1979). Izawa and Bejarano (1981) did not record S. i. imperator for Bolivia, but reported an isolated population on the left bank of the Rio Acre, in the basin of the Rio São Pedro in Brazil, in an area otherwise occupied by S. l. labiatus. Encarnación and Castro (1990) found populations of S. i. imperator (but not S. l. labiatus) on the right and left banks of the Rio Acre near the Quebrada Río Branco, approximately 20 km west of Inapari, close to the region indicated by Izawa and Bejarano (1981). The population on the south bank of the Río Acre is evidently highly restricted, the subspecies not having been found anywhere else further south in Peru despite a number of surveys (Castro et al., 1990). It is not known how far it extends into Peru along the Rio Acre, nor whether it occurs between the Rio Purus and Pauiní and the Rios Purus and Ituxí (Hershkovitz, 1979).
