ABSTRACT: The phalacrid fauna of Southern Introduction Africa was studied. Six new species belonging to the genus are described: O. capriviensis sp.n., The phalacrid fauna of Southern Africa was O. fuscostriatus sp.n., O. rufopunctatus sp.n., O. principally described by Champion in 1925 [Cham- namibiensis sp.n., O. sternosetosus sp.n., O. rufos- pion, 1925] and is known to include 18 species of the ignatus sp.n., as well as one new species of the genus genus Olibrus Erichson, 1845, 4 species of Augas- : S. capriviensis.

The distribution of the genera Phalacrus, pion, O. nigroclavatus Champion, O. natalensis Olibrus, and Stilbus is worldwide, Augasmus is Champion are described for the first time. A key to spread from Japan in the north to New Guinea and Olibrus species from Southern Africa is given. Data Southern Africa.
