Pithecia pissinattii is a species of primate from the genus Sakis , which belongs to the group of New World monkeys . The species occurs in Brazil in the middle Amazon basin between the lower reaches of the Rio Purus and Rio Madeira . So far it is not known how far the distribution area expands to the southwest until itmeetsthe distribution area of Pithecia irrorata .

features

Pithecia pissinattii resembles most of the Mittermeier Nacktges facesaki ( P. mittermeieri ), whose distribution area adjoins southeast on the orographic right side of the Rio Madeira . The head-torso length of the investigated P. pissinattii males is between 45 and 55 cm, that of the females between 43 and 49 cm. The tails of the males are between 42 and 52 cm long, those of the females between 43 and 49 cm. Like all Sakis, they have a shaggy, rough coat that is gray with sprinkles of white. Males get a slightly brownish tinge with age and the fur on the chest turns orange. They have a whitish “ pony ”, which is not as distinct as with other Sakis. The hands and feet of the monkeys are covered with short white hair. The front of the thighs can be darker, brownish, or black. The face of the adult males is almost hairless and from deep reddish to waxy reddish-black color. Young Pithecia pissinattii males can be easily distinguished from those of the Mittermeier nude face jacket, because they lack the conspicuous rosy spots on the skin around the eyes. Foreheads and cheeks of adult females are covered with short white hair, the skin of the face that is not covered with hair is black. In young females, the skin above and below the eyes is light pink, the remaining skin that is not covered with hair is black.

Systematics

Pithecia pissinattii was only in 2014 in a revision of Sakis by Laura K. Marsh described and named a Brazilian veterinarian after Alcides Pissinatti. Pissinatti has done a lot to breed South American monkeys, especially the endangered spider monkeys ( Brachyteles ), in captivity. The various known populations of Pithecia pissinattii were previously assigned to the bald-faced Saki ( Pithecia irrorata ) or Pithecia hirsuta .
