In this paper, an addendum to my 'Revision of the Mydaidae (Diptera) of southern Africa', three new genera and sixteen new species from the Namib Desert and other parts of South West Africa are described. The genus Namamydas Hesse, described 1969, is sunk as a synonym of Namadytes Hesse and a key is given to separate the known species of the latter. A new tribe Halterorchini is erected to accommodate the anomalous genera Halterorchis Bezzi, Nothomydas Hesse, and the other two genera Mimadelphus and Namibimydas. A short descriptive key for the separation of these genera is appended. A revised key to the subfamily Mydainae, to include the new genus Parectyphus, is also given. In 8 text-figures certain genital structures which help to distinguish some of the new species and the more important structures of the new genera are illustrated. A short list of the more important bibliographical references is added.
