Flower visiting records are given for 69 species belonging to six of the seven genera of southern African masarid wasps: Ceramius (14 spp.), Jugurtia (4 spp.), Masarina (3 spp.), Celonites (8 spp.), Quartinia (10 spp.) and Quartinioides (30 spp.). The records, so far assembled, indicate that southern African masarids are most commonly associated with Mesembryanthemaceae (51%) and Compositae (28%), those species visiting flowers of other families such as Campanulaceae (12%), Scrophulariaceae (5%), Leguminosae (Papilionatae) (3%) and Liliaceae (2%) being the exceptions. It is demonstrated that the majority of species exhibit fidelity to particular families or even genera of plants and that some species, at least, are probably of importance as pollinators to the plants which they visit.
