Open encyclopedia reference

The eastern hoolock gibbon (Hoolock leuconedys) is a primate from the gibbon family, Hylobatidae. It is one of three species of hoolock gibbon. This species is found east of the Chindwin River, such as the Mahamyaing Wildlife Sanctuary, and in south west Yunnan of China. Recent study published in April, 2021, in International Journal of Primatology confirmed that this species is not found in India as it was thought to be.
