The Afrotropical species of the genus Jugurtia de Saussure, 1854 (Hymenoptera: Vespidae, Masarinae) are revised. Ten new species from southern Africa are described: damara, einensis, elegans, gariepensis, hessei, mandibulata, namibicola, nigrifrons, tibialis, zebra. The female of nigrifrons is that previously attributed by Gess (1997) to duplicata Richards from which species it is now removed. Also described are the previously unknown males of alfkeni (du Buysson) and simpsoni Meade-Waldo. Full distributional data and distribution maps are given for all species except spinolae (de Saussure)-24 species in all, and forage plant records are included for 17 of these species. A key to species is given. Keywords: Hymenoptera, vespidae, Masarinae jugurtia, new species, Africa, southern Africa, wasp.
