The rare Mountain Nyala (Tragelaphus buxtoni) is limited to central Ethiopia. While superficially similar to the lowland Nyala, it is now considered more closely related to the kudu.The name "Nyala" is the Swahili name for this antelope. The Latin name comes from "tragos" (he-goat), "elaphos" (deer), and George Francis Angas, an English artist and naturalist.
