Abstract: The subgenus Neosciaphobus Apfelbeck, 1922 of the genus Sciaphobus K. Daniel, 1904 (Coleoptera: Curculionidae: Entiminae: Sciaphilini) is discussed, revised, redefined, redescribed and keyed. All included species are redescribed and illustrated. A review of the species of the subgenus Sciaphobus s. str. without long elytral erect setae is given. Sciaphobus (Neosciaphobus) angustus sp. nov. from Albania, S. (Sciaphobus) formaneki sp. nov., and S. (Sciaphobus) pelikani sp. nov. from Montenegro are described and compared with similar species. Four new synonyms are proposed: Sciaphobus curvimanus Apfelbeck, 1922 = S. muelleri Penecke, 1928, syn. nov.; S. squalidus (Gyllenhal, 1834) = Sciaphobus balcanicus Apfelbeck, 1922, syn. nov. = Sciaphobus squalidus alternans Apfelbeck, 1922, syn. nov. = Sciaphobus squalidus ovalipennis Apfelbeck, 1922 syn. nov. A neotype for Sciaphilus subnudus Desbrochers des Loges, 1892 is designated; lectotypes for the following species are designated: Eusomus setosulus Germar, 1824, Polydrusus squalidus Gyllenhal, 1834, Polydrusus vittatus Gyllenhal, 1834, Sciaphilus beckeri Stierlin, 1863, Sciaphobus balcanicus Apfelbeck, 1922, Sciaphobus scheibeli Apfelbeck, 1922, Sciaphilus smaragdinus Boheman, 1840, and Thylacites ningnidus Germar, 1824. Sciaphobus rasus (Seidlitz, 1867) is tranferred from the subgenus Neosciaphobus to the nominotypical subgenus. All the examined types of both subgenera are commented on. Female genitalia of the genus are studied and illustrated for the first time. The following new country records are presented: Sciaphobus ningnidus from Croatia and Montenegro, S. reitteri from Croatia, and S. squalidus from Moldova and Greece.
