Taxonomic notes on the tribe Omiini, with description of one new genus and species, and with revision of genera Anemophilus and Euplatinus (Coleoptera: Curculionidae: Entiminae)

Abstract: Baromiamima gen. n. is erected for a group of species closely related to Omiamima concinna (Boheman, 1834), living in Central and South Europe. Anemophilus gracilipes sp. n. is described from Madeira. Genus Omiamima Silfverberg, 1977 is redefined. Four genera are transferred to the tribe Omiini: Anemophilus Wollaston, 1854 from Trachyphloeini Lacordaire, 1863, Chiloneonasus Reitter, 1913 and Euplatinus Desbrochers, 1907 from Holcorhinini Desbrochers, 1898, and Sitonapterus Reitter, 1913 from Polydrusini Schoenherr, 1823. Three new synonymies of the following genera are proposed: Chiloneonasus Reitter, 1913 and Sitonapterus Reitter, 1913 as junior synonyms of Desbrochersella Reitter, 1906, and Microelytrodon Pic, 1945 as a junior synonym of Chiloneus Schoenherr, 1842. The genera Anemophilus and Euplatinus are redescribed, revised, keyed and illustrated. The following new combinations are proposed: Aomus haifensis (Formánek, 1904), Aomus cypricus (Seidlitz, 1868), Argoptochus albisetus (Borovec, 1998) and Argoptochus hystricus (Borovec, 1998) (all from Omiamima), Chiloneus theresae (Pic, 1945) (from Microelytrodon), Desbrochersella formaneki (Reitter, 1913) (from Chiloneonasus), Desbrochersella sitonoides (Reitter, 1913) (from Sitonapterus), Euplatinus cupripubens (Reitter, 1906) (from Omias Germar, 1817) and Omias ganglbaueri Formánek, 1908 (from Omiamima). Four new species synonymies are proposed: Aomus otiorrhynchoides (Reitter, 1913) as a junior synonym of A. haifensis, Omias lonae (Solari, 1926) and Omias taygetanus (Purkyně, 1949) as junior synonyms of Omias sandneri (Reitter, 1906), and Omias punctatus (Angelov, 1973) as a junior synonym of Omias inermis (F. Solari, 1926). Lectotypes of the following species are designated (current names added in brackets where different): Asphalmus japonicus Sharp, 1896, Chiloneonasus formaneki Reitter, 1913 (i.e. Desbrochersella formaneki (Reitter, 1913)), Euplatinus tigrellus Desbrochers, 1907 (i.e. Euplatinus syriacus Pic, 1898), Euplatinus otiorhynchoides Desbrochers, 1909 (i.e. Euplatinus syriacus Pic, 1898), Otiorhynchus subconstrictus Reitter, 1896 (i.e. Hlavena subconstricta (Reitter, 1896)), Microelytrodon theresae Pic, 1945 (i.e. Chiloneus theresae (Pic, 1945)), Mylacus bulgaricus Purkyně, 1949 (i.e. Omias bulgaricus (Purkyně, 1949)), Mylacus helleri Reitter, 1906 (i.e. Omias helleri (Reitter, 1906)), Mylacus inermis F. Solari 1926 (i.e. Omias inermis (F. Solari, 1926)), Mylacus lonae F. Solari, 1926 (i.e. Omias sandneri (Reitter, 1906)), Mylacus ossae Purkyně, 1949 (i.e. Omias ossae (Purkyně, 1949)), Mylacus taygetanus Purkyně, 1949 (i.e. Omias sandneri (Reitter, 1906)), Mylacus sandneri Reitter, 1906 (Omias sandneri (Reitter, 1906)), and Mylacus cupripubens Reitter, 1906 (i.e. Euplatinus cupripubens (Reitter, 1906)). Holotypes of the following species are designated (current names added in brackets where different): Mylacus brancsiki Reitter, 1906 (i.e. Omias brancsiki (Reitter, 1906)), Mylacus matejkai Purkyně, 1949 (i.e. Omias matejkai (Purkyně, 1949)), Omias fulgidus Formánek, 1909 (i.e. Omiamima fulgida (Formánek, 1909)), Omias ganglbaueri Formánek, 1908, Omias haifensis Formánek, 1904 (i.e. Aomus haifensis (Formánek, 1904)), Omias villosus Formánek, 1911 (i.e. Omiamima villosa (Formánek, 1911)), and Sitonapterus sitonoides Reitter, 1913 (i.e. Desbrochersella sitonoides (Reitter, 1913)). Key to the known Palaearctic genera and a check-list of all Palaearctic genera and species of the tribe Omiini are given. Male and female genitalia of most species are studied and illustrated for the first time.
