Pithecia rylandsi is a primate species from the group of the New World monkeys that occurs in northern Bolivia in the Pando departmentand in southeastern Peru in the Madre de Dios region , as well as possibly in the adjacent part of Brazil ( Rondônia and southwest of Mato Grosso ). This makes it the most southerly Saki species.
features
Pithecia rylandsi is one of the largest saki species, but exact measurements are not yet available. Like all Sakis, they have a shaggy, rough fur. The hair on the top of the head resembles a hood, the tail, which is not used for grasping but for balance, is hairy and bushy throughout. Young animals are blackish, adult specimens are gray-white in color. With age, the monkeys get lighter and lighter until they are almost completely white. The face is hairless and black. The mouth region is bordered by hairy, white lines that are slightly wider in females than in males, which are often missing. The forearms of the females can have a yellowish or blonde tint; this coloration can extend to the breast.
Systematics
Pithecia rylandsi was only in 2014 in a revision of Sakis by Laura K. Marsh described and after Anthony Rylands , one of Conservation International and the International Union for the Conservation of Nature working primate expert and former professor of the Universidade Federal de Minas Gerais , named. The different known populations of Pithecia rylandsi were previously assigned to different types of Saki.
