The genera Chalinus Konow and Mocsarya Konow are revised. Eight species are recognised in Chalinus: C. berlandi Guiglia, C. braunsi (Enslin), C. haugi du Buysson, C. imperialis (Westwood), C. orientalis Guiglia, C. purpureiventris Cameron, C. somalicus Guiglia, C. timnaensis Kraus. Chalinus balianii Guiglia is proposed as a new synonym of C. berlandi Guiglia, C. schulthessi Guiglia as a new synonym of C. braunsi (Enslin), and the synonymy of C. congoensis Guiglia with C. imperialis (Westwood) is reestablished. Two species are recognised in Mocsarya: M. metallica (Mocsáry); M. syriaca Benson. Two nominal species, Oryssus oberthueri Saussure and Oryssus plumicornis Guérin-Menneville are treated as species inquirendae in Chalinus. Keys, redescriptions and distribution maps are provided for all recognised species.
