Taxonomic and faunistic notes on the Holarctic Omiini, with description of six new Omias and one new Euplatinus (Coleoptera: Curculionidae: Entiminae)

Abstract: Six new species of the genus Omias Germar, 1817 from Greece and Bulgaria are described, illustrated and compared with closely related species: O. angelovi sp. nov., O. behnei sp. nov., O. crassirostris sp. nov., O. scrobithorax sp. nov., O. pseudomurinus sp. nov. and O. rilensis sp. nov.; moreover Euplatinus edmundi sp. nov. is described from Turkey, Omias crinitus (Reitter, 1906) is proposed as a junior synonym of Omias pustulatus (Seidlitz, 1868), Omias ganglbaueri Formánek, 1908 as a junior synonym of O. oertzeni (Stierlin, 1887 and Omias nitidulus (Vitale, 1904) as a junior synonym of Euplatinus graecus (Stierlin, 1885). Omias chelmosensis (Meschnigg, 1939) is resurrected from synonymy with O. oertzeni (Stierlin, 1887). Omias graecus (Stierlin, 1884) and O. laevis (Angelov, 1973) are transferred from the genus Omias to Euplatinus Desbrochers des Loges, 1907. Six „Omias“ species from U.S.A. and Canada are proposed as a group of incertae sedis Omias species. Lectotypes of the following species are designated (current names added in brackets where different): Curculio bohemani Zetterstedt, 1837 (i.e. Omiamima mollina (Boheman, 1834)), Mylacus armatus Seidlitz, 1868 (i.e. Omias armatus (Seidlitz, 1868)), Mylacus chelmosensis Meschnigg, 1939 (i.e. Omias chelmosensis (Meschnigg, 1939)), Mylacus desbrochersi Reitter, 1906 (i.e. Omiamima desbrochersi (Reitter, 1906)), Mylacus formaneki Reitter, 1906 (i.e. Omias formaneki (Reitter, 1906)), Mylacus Krüperi Stierlin, 1888 (i.e. Omias krueperi (Stierlin, 1888)), Mylacus martini Pic, 1902 (i.e. Omias glomeratus Schoenherr, 1826)), Mylacus murinus Boheman, 1842 (i.e. Omias murinus (Boheman, 1842)), Mylacus Oertzeni Stierlin, 1887 (i.e. Omias oertzeni (Stierlin, 1887)), Mylacus pustulatus Seidlitz, 1868 (i.e. Omias crinitus (Reitter, 1906)), My- lacus senaci Desbrochers, 1875 (i.e. Humeromima nitida (Boheman, 1842)), Mylacus subplumbeus Desbrochers, 1875 (i.e. Omiamima metallescens (Seidlitz, 1868)), Omias concinnus Boheman, 1834 (i.e. Baromiamima concinna (Boheman, 1834)), Omias globosus Gyllenhal, 1834 (i.e. Omias glomeratus Schoenherr, 1826)), Omias glomeratus Schoenherr, 1826, Omias glomulus Schoenherr, 1832 (i.e. Omias glomeratus Schoenherr, 1826)), Omias micans Seidlitz, 1868 (i.e. Baromiamima micans (Seidlitz, 1868)), Omias mollinus Boheman, 1834 (i.e. Omiamima mollina (Boheman, 1834)), Omias nitidus Boheman, 1842 (i.e. Humeromima nitida (Boheman, 1842)), Omias oblongus Boheman, 1842 (i.e. Baromiamima concinna (Boheman, 1834)), Omias parvulus Boheman, 1834 (i.e. Baromiamima concinna (Boheman, 1834)), Omias rufipes Boheman, 1834 (i.e. Humeromima rufipes (Boheman, 1834)), Omias sericeus Boheman, 1842 (i.e. Baromiamima concinna (Boheman, 1834)), Omias sphaericus Boheman, 1842 (i.e. Omias murinus (Boheman, 1842)), Omias vestitus Boheman, 1842 (i.e. Omias murinus (Boheman, 1842)). Unknown males of Omias formaneki (Reitter, 1906) and Anemophilus gracilipes Borovec, 2006 are described. O. formaneki (Reitter, 1906) is recorded from Albania for the first time, as well as O. verruca Boheman, 1834 from Romania.
