The sable antelope (Hippotragus niger) is a large antelope which inhabits wooded savanna in East and Southern Africa, from the south of Kenya to South Africa, with a separated population in Angola. Taxonomy The sable antelope shares the genus Hippotragus with the extinct bluebuck (H. leucophaeus) and the roan antelope (H. equinus), and is a member of the family Bovidae. In 1996, an analysis of mitochondrial DNA extracted from a mounted specimen of the bluebuck showed that it is outside the clade containing the roan and sable antelopes. The cladogram below shows the position of the sable antelope among its relatives, following the 1996 analysis: Subspecies Hipotragus niger has four subspecies: The southern sable antelope (H. n. niger; also known as the common sable antelope, black sable antelope, Matsetsi sable antelope or South Zambian sable antelope) is regarded as the nominate subspecies, as it was the first one to be described and named in 1838. Often referred to as the black sable antelope because it tends to have the darkest coat, this subspecies occurs south of the Zambezi River, particularly in northern Botswana and in large numbers in the Matsetsi Valley of Zimbabwe, but it is also found in South Africa. In South Africa, most of the commercial sable antelope farmers crossed their Matsetsi sable antelope (indigenous to South Africa) with Zambian sable antelope in the hope to move nearer to the nearly extinct giant sable antelope (that was larger with bigger horns). Currently, only about 15% pure Matsetsi sable antelopes are thought to exist in South Africa. The Matsetsi sable antelope population in Zimbabwe is only 450 (down from 24,000 in 1994). The sable antelope population in South Africa is about 7,000 (commercial and in reserves). Therefore, the Matsetsi sable antelope population apparently is less than 1,500 and declining. However, most of the sable antelope in the reserves are pure Matsetsi sable antelope. Anglo-American recently started a program of breeding pure Matsetsi sable antelope commercially and keeping them pure. The giant sable antelope (H. n. variani; also known as the royal sable antelope) is so named because both sexes are larger and their horns are recognizably longer. It is found only in a few remaining localities in central Angola. It is classified as Critically Endangered on the IUCN Red List and is listed on Appendix I of CITES.
