Chiropotes utahickae

Uta Hick's bearded saki (Chiropotes utahicki) is an endangered species of bearded saki, a type of New World monkey. It is endemic to Brazil, where restricted to the Amazon between the Xingu and Tocantins Rivers. It was formerly treated as a subspecies of the more easterly C. satanas, but its back is pale brownish. The specific name is often modified to utahickae, but this has been discouraged.
