Twenty-four species are treated. Two new synonyms were proposed, <em>Oncocephala kolbei</em> Gestro, 1899a is synonymized with <em>O. promontorii</em> Péringuey, 1898 and <em>O. scabrosa</em> Gestro, 1905 is synonymized with <em>O. severinii</em> Gestro, 1899(1901). Six new species are proposed: <em>Oncocephala susanstainesae </em>Calcetas, Staines &amp; Adorada <strong>sp. nov.</strong> from Namibia<em>, Oncocephala deleoni </em>Calcetas, Staines and Adorada <strong>sp. nov.</strong> from the Democratic Republic of the Congo<em>, Oncocephala camachoi </em>Calcetas, Staines &amp; Adorada <strong>sp. nov.</strong> from Cameroon<em>, Oncocephala eborai </em>Calcetas, Staines &amp; Adorada <strong>sp. nov.</strong> from Equatorial Guinea<em>, Oncocephala dimaculanganae </em>Calcetas, Staines &amp; Adorada <strong>sp. nov.</strong> from Cameroon and <em>Oncocephala demesai </em>Calcetas, Staines and Adorada <strong>sp. nov.</strong> from Togo<em>. Oncocephala methneri</em> Uhmann, 1928 and <em>O. madoni</em> Pic, 1941 are treated as <em>incerte sedis</em>. The genus <em>Oncocephala</em> in Africa is divided into seven species groups (Gestroi, Perrieri, Insignis, Senegalensis, Promentorii, Cuneata and Angusticollis) based on the similarity of their elytral characters. A key to the species groups and species of <em>Oncocephala</em> is provided.</p> ORLANDO A. CALCETAS CHARLES L. STAINES JESSAMYN R. ADORADA VENUS J. CALILUNG BARBARA L. CAOILI SERLIE B.
