The Cixiidae (Hemiptera: Fulgoromorpha) fauna of Namibia and the Cixiidae collection of the National Museum Windhoek are revised. Six species, Atonurus meridianus (Van Stalle, 1984), Eumecurus kibuyanus (Fennah, 1955), E. decempunctatus (Van Stalle, 1984), E. eryx (Fennah, 1957), E. mashonanus (Van Stalle, 1987) and E. incompletus (Van Stalle, 1983), are reported from Namibia for the first time. Thus, 19 Cixiidae species (one Duiliini, 18 Pentastirini) are present in Namibia. In addition, one new species, Eumecurus skofitschii Huang & Holzinger nov. spec., is described from Angola, and Eumecurus zairensis (Van Stalle, 1987) is recorded from Malawi for the first time. Keywords: Hemiptera, Rhynchota, Auchenorrhyncha, Cicadina, Fulgoromorpha, Malawi, Angola, Atonurus, Duilius, Eumecurus, Pentastiridius.
