West Zambian sable antelope or West Tanzanian sable antelope) occurs in central Angola, western Zambia and Malawi and has the largest geographic range of the four subspecies, which extends north of the Zambezi River through Zambia, the eastern Democratic Republic of the Congo and Malawi into southwestern Tanzania. It is classified as Vulnerable. The eastern sable antelope (H. n. roosevelti; also known as the Shimba sable antelope) is the smallest of the four subspecies. It occurs in the coastal hinterlands of southern Kenya, particularly in the Shimba Hills National Reserve, and ranges through the region east of Tanzania's eastern escarpment and into northern Mozambique. In English "great sable antelope", "sable" or the Swahili name mbarapi are sometimes used. An archaic term used in accounts of hunting expeditions in South Africa is "potaquaine"; the origin and exact application are unclear. Local names include swartwitpens (Afrikaans), kgama or phalafala (Sotho), mBarapi or palahala (Swahili), kukurugu, kwalat or kwalata (Tswana), ngwarati (Shona), iliza (Xhosa), impalampala (Zulu) and umtshwayeli (Ndebele).
