Purple-faced langur  (Trachypithecus vetulus)

Description

The purple-faced langur is a long-tailed arboreal monkey endemic to Sri Lanka (4). Coat colour varies with the subspecies, but is generally brownish-black on the body and limbs, whilst the facial whiskers range in colour from white to pale brown and are directed backwards. Newborns, by contrast, possess a pale grey coat, with a brownish tinge on the crown, chest, arms and legs. The thumb of this species is markedly reduced (5). The face is greyish-black, as opposed to purple as its common name suggests (2).
