Revision of the genus Achmonia of Africa south of the Sahara (Coleoptera: Staphylinidae: Staphylininae).

A redescription of the genus Achmonia Bordoni, 2004 is presented. Based on a revision of types and of additional material, seven species are recognized in Africa south of the Sahara and placed into two species groups. All species are described or redescribed and illustrated, four of them for the first time: Achmonia carinata sp. nov., A. kapangana sp. nov., A. knirschi sp. nov., and A. simulator sp. nov. A lectotype is designated for Xantholinus amabilis Boheman, 1848, Eulissus flavomarginatus Bernhauer, 1929 and E. congoensis Bernhauer, 1932. These species are transferred to Achmonia. A lectotype is designated for Eulissus semiflavus Bernhauer, 1913, and E. gerardi Bernhauer, 1929 and the following synonymy is proposed: Achmonia amabilis (Boheman, 1848) = Eulissus semiflavus Bernhauer, 1913, syn. nov. = Eulissus gerardi Bernhauer, 1929, syn. nov. The distribution of the genus in Africa south of Sahara is mapped and a key to species is presented.
