Geog. Distr. Anim.: 224 . Genera: 4 genera with 10 species: Genus Alcelaphus de Blainville 1816 (3 species with 6 subspecies) Genus Beatragus Heller 1912 (1 species) Genus Connochaetes Lichtenstein 1812 (2 species with 5 subspecies) Genus Damaliscus Sclater and Thomas 1894 (4 species with 5 subspecies) Discussion: Living genera assigned to two subtribes by Vrba (1997) , Alcelaphini (including Alcelaphus , Beatragus , and Connochaetes ) and Damaliscini (includes only Damaliscus ), but retention of flehmen behavior, lost in Alcelaphus and Damaliscus ( Estes, 1999 ) , and karyology suggests Beatragus is sister group of Alcelaphus plus Damaliscus ( Kumamoto et al., 1996 ; Robinson et al., 1991 ).
