The horse rams (Hippotragini) are a tribe of the horned family . These antelopes are common in Africa and the Arabian Peninsula .

Many species have a horse-like build, but the name comes from the mane-like hair on the neck. Both sexes always have very long horns that can either be straight or curved. With the exception of the sable antelope, there is no distinctive sexual dimorphism , the sexes are approximately the same size and color.

Roan antelopes have adapted to dry habitats like no other group of hornbears, they inhabit savannas, semi-deserts and deserts. All species are grass-eaters, which are adapted to this food with high-crowned teeth.

These animals are severely affected by human hunting. One of the ten species, the bluebock, became extinct; three more - the mendes and two of the oryx - are highly endangered.

The following genera and species are distinguished:

  • Tribus Hippotragini Sundevall in Retzius & Lovén, 1845
  • Genus Addax Laurillard , 1842

The tribe of the Hippotragini was scientifically introduced by Carl Jakob Sundevall in 1845 under the name Hippotragina. In some cases, the giant sable antelope ( H. n. Variani ) is also considered an independent species. According to genetic studies, four units can be identified within the sable antelope, which in addition to the actual sable antelope, the East African sable antelope and the giant sable antelope also include a population in Zambia and corresponds to the subspecies H. n. kirkii . A fifth independent line that has not yet been defined in detail may exist in western Tanzania.
