Black Bearded Saki (Chiropotes satanas)
Chiropotes or bearded sakis, is a genus of New World monkeys. They live in the eastern and central Amazon in South America, ranging through southern Venezuela, Guyana, Suriname, French Guiana and northern and central Brazil
Until recently, only two species were recognized in this genus, but Chiropotes israelita was re-validated in 2003 (having long been considered a synonym of Chiropotes), where it – based on differences in colour of pelage, karyotype, and molecular analysis – also was recommended treating Chiropotes chiropotes and Chiropotes utahickae as species separate from Chiropotes satanas.
