With the alias of Kerchief Leaf Monkey, it belongs to the Cercopithecidae family of Primates order. Its scientific name is Presbytis pileata (Latin), or Capped Leaf Monkey (English).

The body hair is silver gray or yellow. Its dorsal hair, outer sides of the four limbs and tail end are black grey. The hair on top of the head is fluffy, without whirling hair. The crest is dark colored as wearing a small cap, which is a brilliant contrast to light colored whiskers. Its face is black. The skin around eyes and mouth forms eye-rim and mouth-ring for lack of pigment. The hands and feet are black. The salivary secretory is advanced, and the stomach is bag-shaped adapting the digestive system to its leaf-eating nature, thus it has no cheek pouch of polyphagous cercopithecine monkey.

Inhabiting in tropical and subtropical forests, it lives in groups of 10 to 30 monkeys. It dwells on trees and feeds on different kinds of fresh and delicate leaves, twigs, buds, flowers, and fruits.

In China, there are only 500 to 600 Capped Leaf Monkeys, seen in the valley of the Dulong River of Gongshan in northwestern Yunnan Province.
