Amazon, Callitrichidae, Tamarins, Range extensionAbstract
The known range of the White Saddle-back Tamarin (Leontocebus melanoleucus) is restricted to the region between the Juruá and Tarauacá rivers in the southwestern Amazon. Documented records east of the Tarauacá along both banks of the Muru river in central Acre expand its distribution eastwards by over 60 km and suggest the Envira river marks the actual limit of its range, increasing its probable range by 39.5%.
