Pithecia isabela (English: Isabel's Saki) is a primate species from the group of New World monkeys that occurs in eastern Peru between the Río Marañón and Río Ucayali . The relatively small distribution area roughly covers the area of the Pacaya-Samiria nature reserve.
features
Pithecia isabela reaches a total length of 76 to 92 cm, the tail has a length of 40 to 48 cm. The males are blackish in color with light spots on the back and arms and often a coppery tinge. Females are more of a dark grayish color with brownish hair tips. In both sexes, the tops of the hands and feet are covered with short white hair. The species is characterized by a white spot above each eye, a feature that Pithecia isabela shares with Pithecia napensis from the Ecuadorian Amazon. In Pithecia napensis, however, the spots are much closer together, converge far over the forehead and increasingly grayish on the face, while in Pithecia isabela they are much smaller and more diffuse and do not extend to the face. Pithecia napensis appears bulkier and larger and the males have a lighter, more orange-appearing breast, while the breasts of the males of Pithecia isabela are more orange-brown.
Systematics
Pithecia isabela was only newly described in 2014 during a revision of the Sakis and named in honor of Isabel Godin des Odonais , who made a grueling and dangerous journey through the Amazon region in the 18th century to find her missing husband, the French naturalist Jean Godin . The monkeys had previously been assigned to the equatorial saki ( Pithecia aequatorialis ).
