Lophoceros

The genus Lophoceros was introduced in 1833 by the German naturalists Wilhelm Hemprich and Christian Gottfried Ehrenberg to accommodate Buceros, Lophoceros, forskålii.^[1] This is now considered as a junior synonym of the nominate subspecies of the African grey hornbill (Lophoceros nasutus nasutus).^[2] The genus name comes from the Ancient Greek λόφος (lóphos), meaning "crest", and κέρας (kéras), meaning "horn".^[3]

The species now placed in this genus were formerly included in the genus Tockus. A molecular phylogenetic study published in 2013 found that Tockus was divided by a deep phylogenetic split into two major groups. The genus Lophoceros was therefore resurrected to contain one of these groups.^[4][5]

The genus contains 8 species:^[5]
