The white-headed langur (Trachypithecus leucocephalus) is a Critically Endangered species of langur endemic to Guangxi, China.[1]

It was formerly considered a subspecies of the Cat Ba langur (T. poliocephalus), which is now thought to be endemic to Vietnam.[2]
Its taxonomy was previously uncertain; it has been considered a partially
Populations of the white-headed langur in Chongzuo and Fusui County display notable genetic divergence from the rest of the species, and it has thus been proposed they be treated as evolutionarily significant units.[1]
Description
The white-headed langur is blackish in color with white crown, cheeks, and neck (in contrast to the similar T. poliocephalus, which has a golden crown, cheeks, and neck).[5]
Distribution
The white-headed langur has a very small range in the province of Guangxi in southernmost China, endemic to karst hills, where it is known from a few scattered populations. The Zuo River separates its range from the one of the François' langur farther north.[1]
