Brachyteles arachnoides (ZMB_MAM 206)

The specimen of the southern muriqui, Brachyteles arachonoides, is represented by only a flat skin. The material is the only primate collected by Sellow whose label bears a specific locality other than simply the state or country where it was collected. The label reads “Ypanema,” the same locality where Natterer also collected specimens of B. arachnoides (see Pelzeln 1883). In the absence of contrary evidence, we assume that this locality is correct.
