The Mittermeier Nude Face Kaki ( Pithecia mittermeieri ) is a species of primate from the New World monkey group that occurs in the Amazon basin south of the Amazon between Rio Madeira and Rio Tapajós . Most of the specimens are likely to live in the Brazilian state of Mato Grosso , north of Aripuanã , but there are indications that the species has historically been found further southwest on Bolivian territory in the catchment area of Río Mamoré and Rio Guaporé .
features
The Mittermeier Nacktgesichtsaki reaches a head-trunk length of 35 to 37 cm (females) or 45 to 46 cm (males) and has a 41 to 49 cm long tail. In terms of color, Pithecia mittermeieri is one of the most variable types of Saki. The relatively long back hair of the adult males is gray with sprinkles of white. The hands and feet are covered with short white hair. The front of the legs is black. The main hair (the " pony ") reaching forward into the face is white and in old males forms a white band above the face. Females are less greyish in color than males and the fur makes a slightly brownish impression. With advancing age, the fur becomes increasingly gray, but due to the lack of white sprinkles it is never as light as the fur of the males. In both sexes, the bare skin of the face is black, and the fur on the chest and between the legs around the genital organs is orange, similar to Pithecia pissinattii .
Systematics
The Mittermeier nude-faced kaki was only newly described in 2014 during a revision of the Sakis and named in honor of the American anthropologist and primatologist Russell A. Mittermeier , President of Conservation International and for a long time chairman of the IUCN's Primate Specialist Group . The monkeys had previously been assigned to the bald-faced Saki ( Pithecia irrorata ).
status
The distribution area, which was originally completely covered by forest, has led to extensive road and rail construction in the area between Rio Madeira and Rio Tapajós in the last two centuries and the Brazilian development program Polonoroeste in the 1980s, leading to the destruction of large areas of the primate species' habitat, so that the Landscape today may only be half or less covered by forests. As a result, the occurrence of the Mittermeier Nacktges facesakis is now strongly split, possibly also hybridization zones with other, closely related species developed.
The only known keeping in European zoo history was in Cologne from the 1960s to 1980s, but under the species name Pithecia monachus , later also under Pithecia irrorata .
