ON THE TAXONOMY AND NOMENCLATURE OF SOME MECININI (COLEOPTERA, CURCULIONIDAE)

In accordance with the Code, ten actions are taken to preserve nomenclatural stability of names of taxa currently belonging to <em>Mecinini</em>. Following the provisions of ICZN Article 23.9.1, <em>Cleopomiarus graminis</em> (Gyllenhal, 1813) (formerly <em>Rhynchaenus</em>) is made a <strong>nomen protectum</strong> and <em>Curculio</em> <em>ellipticus</em> Herbst, 1795 is made a <strong>nomen oblitum</strong>; <em>Rhinusa</em> <em>antirrhini</em> (Paykull, 1800) (formerly <em>Curculio</em>) is made a <strong>nomen</strong> <strong>protectum</strong> and<em> Curculio noctis</em> herbst, 1795 is made a <strong>nomen</strong> <strong>oblitum</strong>; having met the conditions of ICZN article 75.3 the neotypes of the following taxa are designated:<em> Curculio antirrhini</em> Paykull, 1800,<em> Curculio cinctus</em> Rossi, 1790<em>, Curculio</em> <em>curvirostris</em> Rossi, 1790, <em>Curculio linariae</em> Panzer, 1792, <em>Cionus</em> <em>thapsicola</em> Germar, 1821, <em>Mecinus collaris</em> Germar, 1821. Lectotypes of <em>Curculio</em> <em>ellipticus</em> Herbst, 1795, <em>Gymnetron</em> <em>eversmanni</em> Rosenschöld, 1838, <em>Mecinus</em> <em>barbarus</em> Gyllenhal, 1838, and <em>Mecinus</em> <em>longiusculus</em> Boheman, 1845 are also designated. <em>Rhinusa linariae</em> (Panzer, 1792) (formerly <em>Curculio</em>) remains the valid name of the taxon since<em> Curculio curvirostris</em> Rossi, 1790 (non Fabricius, 1781 nec Herbst, 1784) is unavailable; <em>Mecinus collaris</em> Germar, 1821 remains the valid name of the taxon since <em>Curculio cinctus</em> Rossi, 1790 (non Drury, 1782 nec Geoffroy, 1785) is unavailable. The following new synonymies are proposed:<em> Mecinus barbarus</em> Gyllenhal, 1838 = <em>Mecinus longiusculus</em> Boheman, 1845 <strong>n. syn</strong>., = <em>Mecinus teretiusculus</em> Boheman, 1845 <strong>n. syn</strong>., = <em>Mecinus</em> <em>filiformis</em> Aubé, 1850 <strong>n. syn</strong>.; <em>Rhinusa florum</em> (Rübsaamen, 1895) = <em>Gymnetron smreczynskii</em> Fremuth, 1972 <strong>n. syn.</strong>; <em>Rhinusa</em> <em>tetra</em> (Fabricius, 1792) = <em>Cionus thapsicola</em> Germar, 1821 <strong>n. syn.</strong> <em>Rhinusa eversmanni</em> (Rosenschöld, 1838) is the name proposed for <em>Rhinusa thapsicola </em>sensu auctorum (non Germar, 1821)
