This beautiful and extremely rare colobine monkey is part of the genus Trachypithecus, in which the dark chocolate brown coat of adults contrasts spectacularly with the golden orange fur of infants, which turns to whitish-grey in juveniles (2) (3). The head and neck of adults are golden to yellowish-white in T. p. poliocephalus, with the pointed crest of hair on the top of the head being the most brightly coloured (3), and creamy-white in T. p. leucocephalus. A grey V-shaped area runs from the thighs to the back (3), and the fur of the pubic region ranges from white to pale orange (4). Adults are also adorned with a cape-like area of longer fur across the shoulders (3). The hands and feet are very slim, and the thumbs are notably shorter than in other primates (4).
