黑腿白臀叶猴 (Pygathrix nigripes)
Three species of doucs are recognized: the black-shanked douc (P. nigripes), red-shanked douc (P. nemaeus), and grey-shanked douc (P. cinerea). The black-shanked douc is identified in the field by its black legs and arms, grey belly, blue face with yellow eye-rings, and a long white tail.
The black-shanked douc is endangered with a restricted range in Vietnam and Cambodia . In Vietnam, it is estimated that there are between 3,300 and 4,000 individuals , with only a number of ecological research on the species in the wild [3,4,5].
