Indian crested porcupine

Zootierliste says they are Indian but in mine opinion they also could be Africans.
Can someone tell me the differences ( exept the country of orgin ofcourse ! ) ?

I'm not sure how accurate this is, and there might be an easier way, but I've noticed that in general Africans (H. cristata) tend to have white-tipped crests, and Indian porcupines have brown crests; their general colouration is lighter than that of Africans too.
