Himalayan Large-eared Flying Squirrel

The Himalayan large-eared flying squirrel is found in south-western Yunnan Province, China, and adjoining Myanmar, and is the only member of its genus. It has a larger external ear than most other flying squirrels and a less-developed uropatagium, the membrane between the hind legs and tail (Wikipedia, general species account).

It can also be told apart by the development of its cheek teeth and by its larger glans penis (Wikipedia, general species account).
