Larvae of Simulium (Freemanellum) hessei Gibbins, 1941, S. (Metomphalus) letabum de Meillon, 1935, S. (Nevermannia) rutherfoordi de Meillon, 1937, S. (Nevermannia) katangae Fain, 1951, S. (Pomeroyellum) bequaerti Gibbins, 1936, S. (Pomeroyellum) harrisoni Freeman & de Meillon, 1953 and S. (Pomeroyellum) merops de Meilion, 1950 are descriptionbed for the first time from specimens collected in southern Africa. Descriptions include ecologically useful information, such as cephalic-fan structure, which is normally not included in formal taxonomic descriptionptions. Cephalic fan rays of S. hessei bear two rows of long and flexible microtrichia with curved tips which hook around the base of microtrichia on adjacent rays to form a coupling network. A checklist of southern African blackflies is provided.
