Pithecia hirsuta ( Latin hirsutus "hairy", English: Hairy Saki) is a primate species from the New World monkey group that occurs in the northwestern Amazon basin between the Rio Japurá in the north and the Rio Napo in the south. The distribution area is in the extreme south of Colombia ( Departamento de Amazonas ), in northwestern Peru and in the eastern continuation of the region in Brazil. How far west the distribution area extends is not yet known. To the west is the occurrence of Miller's monk monkeys ( P. milleri ). A German name for the species has not yet been established, Brehm called it shaggy monkey, in a caption in the new description (Figure 16) the name black-bearded monk monkey can be found.
features
Pithecia hirsuta reaches a head-trunk length of about 50 cm, the tail is longer. Males can grow a little larger than females; her tail is longer. Pithecia hirsuta has the most monochrome fur of all saki species . The sexual dimorphism is also only very slight. Males and females are blackish, the fur is slightly lightly dotted with a few light hair tips, a little more in the females than in the males. The hands are white in both sexes. Males are predominantly black, the head is brownish aguti, the breast black or brownish. The lips and the narrow stripes that contrast the hairless mouth and nose region in color are white or cream-colored. The hairless skin of the face is black with the exception of pink or light spots above the eyes. The scrotum is black, the penis pink. The female's lips are not white. The hair around the face is blacker than that of the males and is not aguti-colored. The skin around the eyes, above the mouth and on the chin is pink.
Systematics
The shape was described in 1823 by the German scientist Johann Baptist von Spix after his expedition to Brazil. The holotype was prepared sitting on a branch and is in the Munich State Zoological Collection . Pithecia hirsuta was later synonymous with the monk monkey ( Pithecia monachus ) . Only in 2014, in a revision of the Sakis , was Pithecia hirsuta recognized again as an independent species.
