Abstract: Afrotropical species of the genus Mentophilonthus Levasseur, 1966 (Coleoptera: Staphylinidae) are revised taxonomically. Twenty species are reco- gnized, including six new ones: M. crocuta sp. nov. (Ghana), M. equus sp. nov. (Malawi), M. hystrix sp. nov. (Namibia), M. manis sp. nov. (Gabon), M. struthio sp. nov. (Sudan, Democratic Republic of the Congo), and M. vanellus sp. nov. (Democratic Republic of the Congo). Six species are transferred to Mentophilon- thus from the genus Philonthus Stephens, 1829: M. curiosus (Tottenham, 1949) comb. nov., M. dilucidus (Tottenham, 1962) comb. nov., M. ochrigonalis (Tot- tenham, 1962) comb. nov., M. reinecki (Schubert, 1902) comb. nov., M. schoutedeni (Bernhauer, 1928) comb. nov., and M. tristichus (Cameron, 1929) comb. nov. Mentophilonthus bangoranensis (Levasseur, 1980), syn. nov., is synonymized with M. ochrigonalis Tottenham, 1962; M. seriatipennis (Bernhauer, 1928), stat. restit. is removed from the synonymy with M. dilutior (Bernhauer, 1928). A lectotype is designated for Philonthus schoutedeni Bernhauer, 1928 and P. seriatipennis Bernhauer, 1928. All species are (re)described and morphological details of some species and aedeagi of all species are figured. A key to Afrotropical species of the genus Mentophilonthus is provided. A list of all Mentophilonthus species is provided along with their known distribution.
