On the identity of Rhinusa hispida (Brulle and its current synonyms (Coleoptera: Curculionidae)

Abstract

From examination of type specimens the authors establish that Rhinusa hispida sensu auctorum is not the same species as R. hispida (Brullé, 1832), which is instead synonymous with R. tetra (Fabricius, 1792) (syn. n.). Moreover, under the name R. hispida sensu auctorum two distinct taxa are confused, which can be distinguished from each other by taxonomic, biological and genetic differences: R. pilosa (Gyllenhal, 1838) and R. brondelii (Brisout, 1862), stat. n. (= R. lanuginosa (Wollaston, 1875), syn. n.). Gymnetron vulpes Lucas, 1849 (= G. marmota Fairmaire, 1883, syn. n.), previously placed under synonymy of R. hispida (Brullé), is transferred to the genus Mecinus and considered a distinct species. A neotype of G. pilosum brondelii Brisout and lectotypes of G. hispidum Brullé, G. pilosum Gyllenhal, G. vulpes Lucas and G. lanuginosum Wollaston are designated.
