Eastern hoolock gibbon

The eastern hoolock gibbon (Hoolock leuconedys) is a primate from the Hylobatidae (gibbon) family. The species is found in extreme eastern corner of Assam and parts of Arunachal Pradesh, Myanmar east of the Chindwin River, and in south west Yunnan of China.

Classification
Mootnick and Groves stated that hoolock gibbons do not belong in the genus Bunopithecus, and placed them in a new genus, Hoolock. This genus was argued to contain two distinct species which were previously thought to be subspecies: Hoolock hoolock and Hoolock leuconedys.
