Pithecia inusta is a primate species from the group of New World monkeys that occurs in central eastern Peru on both sides of the upper reaches of the Río Ucayali and in the adjoining extreme west of Brazil on the lower reaches of the Rio Juruá and possibly also south of the lower reaches of the Rio Javari .
features
The head-torso length of the examined males and females of P. inusta is 37 to 42 cm. The male's tail is 30 cm long, the tails reach lengths of 30 to 50 cm. Like all Sakis, Pithecia inusta has a shaggy, coarse fur, which consists of black hair with white tips, so that overall a gray to gray-black color appears. The females are rather medium gray, the males rather dark gray to gray-black. Caused by light brown hair tips, the ruff of the males is brown. The hands and feet of the monkeys are covered with short whitish hair. The face of the females is covered with short white hair, in the males the facial hair is brownish. The facial coloring of the males led to the species' scientific name ( Latin : inusta = burned). In both sexes, the face is surrounded by a ring of gray hair. The region around the mouth and nose is hairless and black. Narrow white hairbands extend along the lips.
Systematics
Pithecia inusta was described in 1824 by the German scientist Johann Baptist von Spix after his expedition to Brazil, but in 1913 it was synonymous with the monk monkey ( Pithecia monachus ) by the US zoologist Daniel Giraud Elliot . Only in 2014, in a revision of the Sakis , was Pithecia inusta recognized again as an independent species.
