The correct genus name is Asiatic wild ass, Asian wild ass or ... Kulan.
The 5 conventionally recognised subspecies are:
Equus h. hemionus - the Mongolian Kulan (in northern Mongolia) (E. h. luteus - the Gobi Kulan in southern Mongolia and northern China, is probably a synonym of E. h. hemionus (Oakenfull et al. 2000, Grubb 2005))
E. h. khur – the Khur (India)
E. h. kulan the Turkmen Kulan (in Turkmenistan, re-introduced in Kazakhstan, Uzbekistan and Ukraine)
E. h. onager - the Onager (Iran, introduced in Saudi Arabia)
E. h. hemippus – the Syrian Wild Ass (Extinct, formerly from Syria south into the Arabian Peninsula)

Nice assemblage of species ... How are the kulan getting along with the *** camels. Some zoos have had issues with them.
