The white-cheeked macaque (Macaca leucogenys) is a species of macaque found only in Mêdog County in southeastern Tibet and Arunachal Pradesh in northeastern India. The white-cheeked macaque lives in forest habitats, from tropical forests to primary and secondary evergreen broad-leaved forests and mixed broadleaf-conifer forests. The species was first described by Chinese primatologists Cheng Li, Chao Zhao, and Peng-Fei Fan, in the American Journal of Primatology in 2015. It is one of twenty-three extant species in the genus Macaca, and the most recent to be formally described to science. While the species' exact conservation status has not yet been determined, it is likely threatened by poaching, deforestation, and increased human development of its habitat, much like the other primates which inhabit the area.
