Type locality and geographic distribution
Lönnberg (1940) indicated "Santo Antonio, western side of Rio Eiru near the confluence with Rio Juruá″ as the provenience of the material used by him to describe his Mystax imperator subgrisescens.
Tamarinus subgrisescens occurs in the Brazilian states of Acre and Amazonas, the Peruvian departments of Madre de Dios and Ucayali, and the Bolivian department of Pando. In Bolivia (Fig. 10), this species is recorded in the Muyumanu River Basin, on the border of Peru, at the south Tahuamanu River, and at sites along the right (south) bank of the Acre River (Izawa & Bejarano, 1981; Buchanan-Smith et al., 2000), including Cobija. In Peru, there are records of T. subgrisescens in localities along Madre de Dios and Manu Rivers, at the Curanja River (department of Ucayali), Atalaya, the mouth of Urubamba River, and Iñaperi (Encarnación & Castro, 1990); the western limit of the species seems to be the lowlands bordering the Fitzcarrald Arch. In Brazil, T. subgrisescens occurs along the right bank of the upper Juruá River (state of Acre and the Envira River, municipalities of Feijó and Cruzeiro do Sul) and the southwestern state of Amazonas, in Pauiní (west bank of Purus River), the northernmost reliable limits of the species to date (Fig. 10).
