In India there are two main species of wild bovines, the water buffalo, which also is a domestic beast, and the gaur, also known as seladang (Malay) and akin to our wild banteng cattle. May be other species as well but definitely not cape buffalo.

Writers also refer sometimes to wild bison, which I believe is the gaur (???). i don't believe there is any actual wild bison in India.

A good source of information is the ultimate ungulate website.
