As a preliminary step towards the development of a key to genera of several families of Afrotropical Chalcidoidea, seven new genera in four families are described: Cerocephalidae–Milokoa Mitroiu, gen. nov. (type species: Milokoa villemantae Mitroiu, sp. nov.); Epichrysomallidae–Delvareus Rasplus, Mitroiu & van Noort, gen. nov. (type species: Delvareus dicranostylae Rasplus, Mitroiu & van Noort, sp. nov.); Pirenidae–Afrothopus Mitroiu, gen. nov. (type species: Afrothopus georgei Mitroiu, sp. nov.); Pteromalidae–Kerangania Mitroiu, gen. nov. (type species: Kerangania nuda Mitroiu, sp. nov.), Pilosalis Mitroiu, Rasplus & van Noort, gen. nov. (type species: Pilosalis barbatulus Mitroiu, sp. nov.), Scrobesia Mitroiu & Rasplus, gen. nov. (type species: Scrobesia acutigaster Mitroiu & Rasplus, sp. nov.), and Spiniclava Mitroiu & Rasplus, gen. nov. (type species: Spiniclava baaiensis Mitroiu & Rasplus, sp. nov.). Additionally, the following new species are described: Pilosalis bouceki Mitroiu & Rasplus, sp. nov., Pilosalis eurys Mitroiu & van Noort, sp. nov., Pilosalis minutus Mitroiu, sp. nov., Pilosalis platyscapus Mitroiu, Rasplus & van Noort, sp. nov., Scrobesia pondo Mitroiu, sp. nov., and Spiniclava setosa Mitroiu, sp. nov. All taxa are illustrated and the relationships with similar taxa are discussed. For each non-monotypic genus a key to species is provided.
