Onthophagus cervicornis Kirby, 1825, new synonym under Onthophagus dama (Fabricius, 1798) (Coleoptera, Scarabaeidae, Scarabaeinae).

After examining syntypes of Onthophagus cervicornis Kirby, 1825, previously considered to be a synonym of the North American Onthophagus striatulus (Palisot de Beauvois, 1809), we confirm the true identity and new synonymy under South Asian Onthophagus dama (Fabricius, 1798).
