Miller's saki

Miller's saki (Pithecia milleri) is a saki monkey in the genus Pithecia, family Pitheciidae, the New World monkeys that also include the other titis, the sakis and the uakaris. The Mammal Diversity Database credits the species name to J. A. Allen, 1914 and lists its country distribution as Colombia, Ecuador and Peru. Also known as Miller's monk saki, it ranges across parts of southwestern Colombia, northeastern Ecuador and perhaps adjacent areas of Peru. J. A. Allen first described it as a species, it was demoted to a subspecies of the monk saki in 1987 and raised back to full species status in 2014. Confusion over saki taxonomy arose partly from poorly labelled museum specimens. Males are darker grizzled black with brown on the face and forearms, and females are more grayish. The Mammal Diversity Database gives its IUCN Red List status as Vulnerable.
