In revising the afrotropical genera Stenopogon and Rhacholaemus new taxa have been described and taxonomic changes made:
     New genera: Afroscleropogon (Genotype Dasypogon dilutus Walker, 1851); Haroldia (Genotype Stenopogon trivialis Oldroyd, 1974).
     New species: Afroscleropogon: bullingtoni, clementsi, lavignei, nagatomii; Haroldia: oldroydi; Rhacholaemus: artigasi, fisheri, grimmi, hradshyi, josephi, nelsoni, tsacasi; Stenopogon: lehri.
     New combinations: Transferred to Afroscleropogon: armatus (from Stenopogon), braunsi (from Stenopogon), dilutus (from Dasypogon). Transferred to Haroldia: trivialis (from Stenopogon). Transferred to Rhacholaemus: antigenes (from Dasypogon).
     New Synonyms: Stenopogon atrox Oldroyd, 1974 and S. compactus Oldroyd, 1974 = Rhacholaemus variabilis Hermann, 1907.
     Lectotype designation: Rhacholaemus variabilis Hermann, 1907.
     Keys to the genera of afrotropical Stenopogoninae and the species of Afroscleropogon, Haroldia and Rhacholaemus are provided. Only one species of Stenopogon is believed to be present in the Afrotropics - the newly described S. lehri. The distributions and systematic positions of taxa are discussed.
