Uta Hick's bearded saki

Uta Hick's bearded saki (Chiropotes utahicki) 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 Hershkovitz, 1985 and lists its country distribution as Brazil. Also known as Uta Hick's saki, it is endemic to Brazil and restricted to the Amazon between the Xingu and Tocantins rivers. It was formerly treated as a subspecies of the black bearded saki but has a pale brownish back, and the English Wikipedia article calls it endangered. The name utahickae is often used, but the database treats it as an unjustified emendation of the original spelling utahicki. The Mammal Diversity Database gives its IUCN Red List status as Not Evaluated.
