Abstract
The species of Rhinusa Stephens, 1829 (Curculionidae, Curculioninae, Mecinini) belonging to the R. linariae, R. herbarum, R. melas and R. mauritii groups are revised. The R. linariae group includes three species: R. linariae (Panzer, 1795), R. brisouti (Faust, 1891) and R. kumatschevi (Bajtenov, 1977). The R. herbarum group also includes three species: R. herbarum (H. Brisout de Barneville, 1863), R. mateui (Hoffmann, 1965) and R. vulpeculus (Reitter, 1907). The R. melas group includes two species: R. melas (Boheman, 1838) and R. korotyaevi sp. n. (Israel, Jordan). Lastly, the R. mauritii group is monobasic. The lectotypes of Gymnetron consors Desbrochers des Loges, 1898, Gymnetron herbarum H. Brisout de Barneville, 1863, Gymnetron heydeni Desbrochers des Loges, 1869, and Gymnetron melas Boheman, 1838 are designated. The following new synonymy is proposed: Rhinusa herbarum (H. Brisout de Barneville, 1863) = Gymnetron semirufum Desbrochers des Loges, 1898 (syn. n.). For each species treated, description or redescription, notes on type specimens, synonymies, comparative notes, distribution, bionomics when available, photographs of the habitus and drawings of the rostra, genitalia and other structures useful for taxonomy are provided. A key including all the groups of Rhinusa as currently considered is provided for the first time.
