|Range Description:||Saguinus imperator subgrisescens Bolivia, Brazil, Peru|
Southwestern Amazon, in Brazil along the east (right bank) of the upper Rio Juruá east to the Rios Tarauacá and Juruparí, to the Brazil/Peruvian frontier. Into Peru, west from the Juruá headwaters, it occurs as far as the foothills of the Andes in the upper Río Ucayali, east of the mouth of the Río Apurimac and to the south of the Ríos Urubamba and Inuya. Its range extends east into Bolivia on both sides of the Río Madre de Dios (Izawa, 1979). It is probably limited to the south of the Río Tahuamanú. Izawa and Bejarano (1981) reported it only from the Río Muyumanu basin, a south bank tributary of the Río Tahuamanú. Castro et al. (1990) found that it was absent from the area between Iñapari (just south of the Río Acre) and Iberia (north bank of the Río Tahuamanú) in Peru where S. l. labiatus occurs. Aquino and Encarnación (1994) extended the range indicated by Hershkovitz (1979) east to the basin of the Río Tambopata to the Bolivian border, indicating that the Río Madidi, an eastern tributary of the Río Beni in Bolivia, may mark the southern limit to this species.
