About Pithecia chrysocephala I.Geoffroy Saint-Hilaire, 1850
The golden-faced saki, with the scientific name Pithecia chrysocephala, is a species of saki monkey, which is a type of New World monkey. It is found in Brazil, in the area north of the Amazon River, occurring on both sides of the Rio Negro. This species was previously classified as a subspecies of the white-faced saki (P. pithecia), and was elevated to full species status in 2014. The species gets its name from the coloration of male individuals: males have black body hair, and orange or red-brown facial hair. Females have a lighter overall body color, more bare skin on the face, lines of orange hair that extend downward from below the eyes around the snout, and orange ventral fur. Compared to the white-faced saki, the golden-faced saki has a smaller cranial vault that is less prognathic and less spherical.
