The bat-eared fox, like many so called species of fox is not a true fox, but actually comes from the Genus Otocyon. Recent work genetic work has allowed them to be placed (with reasonable confidence) as sister clade to Nyctereutes (racoon dogs) and Vulpes – the true foxes.
There are two subspecies, one which exists in Southern Africa, and the other which inhabits east Africa, however these are not different enough to be separate species. As you can see from the map, these two populations are not split by a huge distance and it is quite possible that at one time they were one super population.
They are found in the Kruger, though only seemed to arrive in recent times.
