Reddish-brown bearded saki

Reddish-brown bearded saki (Chiropotes sagulatus) is a bearded saki in the genus Chiropotes, family Pitheciidae, the New World monkeys that also include the other titis, the sakis and the uakaris. The Mammal Diversity Database credits the species name to (Traill, 1821) and lists its country distribution as Brazil, French Guiana, Guyana and Suriname. It is endemic to Brazil, French Guiana, Guyana and Suriname. The English Wikipedia article says the IUCN notes it is possibly a synonym of Chiropotes israelita, though the two populations of sakis may be distinct species, and the database applies the name sagulatus to the populations previously attributed to israelita. The Mammal Diversity Database gives its IUCN Red List status as Least Concern.
