The impala (pronounced /ɪmˈpɑːlə,-ˈpalə/) (Aepyceros melampus) is a medium-sized antelope found in eastern and southern Africa. The sole member of the genus Aepyceros, it was first described by German zoologist Martin Hinrich Carl Lichtenstein in 1812. Two subspecies are recognised—the common impala, and the larger and darker black-faced impala.
