Vanzolini's bald-faced saki

Vanzolini's bald-faced saki (Pithecia vanzolinii) is a saki monkey in the genus Pithecia, 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, 1987 and lists its country distribution as Brazil. Its range is in western Brazil, and it is named after the Brazilian zoologist Paulo Vanzolini. Hershkovitz first described it as a subspecies of the bald-faced saki, and it was raised to full species status in 2014. After no records in nature for many years, an individual was photographed in the wild in 2017, and a survey of the Eiru River in early 2017 recorded 21 sightings of 12 groups totalling 34 individuals. Hunting of sakis by local people may threaten its survival. The Mammal Diversity Database gives its IUCN Red List status as Not Evaluated.
