Asinus

Asinus is a subgenus of Equus that encompasses several subspecies of the Equidae commonly known as wild asses, characterized by long ears, a lean, straight-backed build, lack of a true withers, a coarse mane and tail, and a reputation for considerable toughness and endurance.

The common donkey is the best-known domesticated representative of the subgenus, with both domesticated and feral varieties. Among the wild ass species, several never-domesticated species live in Asia and Africa, with the extinct European wild ass species formerly inhabiting Europe.
