On the identity of some weevil species described by Johann Christian Fabricius (1745–1808) in the Museum of Zoology of Copenhagen (Coleoptera, Cucujoidea, Curculionoidea, Tenebrionoidea)

Abstract. The types of thirty-two nominal weevil species described by Johann Christian Fabricius are reviewed and lecto- and paralectotypes are designated for twenty-two of them. A neotype is designated for Curculio sticticus Fabricius, 1777. Protapion varipes (Germar, 1817) is declared a nomen protectum over Curculio flavipes Fabricius, 1775. Based on a study of syntypes, Rhinomacer curculioides Fabricius, 1781 is confirmed as a member of Mycterus (Mycteridae), Bruchus undatus Fabricius, 1787 is tentatively transferred to Erotylidae, Curculio fulvirostris Fabricius, 1787 and Anthribus roboris Fabricius, 1798 are confirmed as members of Salpingus (Salpingidae), and Brachycerus cristatus Fabricius, 1798 is transferred to Tenebrionidae. Based on lectotype designation, Curculio caninus Fabricius, 1792 is confirmed as a synonym of Sitona lineatus (Linnaeus, 1758) and Curculio innocuus Fabricius, 1802 as a synonym of Cneorhinus barcelonicus (Herbst, 1797). Bruchus rufipes Fabricius, 1792 is not considered an available species name, but a later use of Bruchus rufipes Olivier, 1790. Cossonus incisus Pascoe, 1885 is reinstated as valid from synonymy under Cossonus illigeri Champion, 1909 and Cossonus vulneratus Illiger, 1805 from synonymy under Cossonus canaliculatus (Fabricius, 1792) (a primary homonym of Curculio canaliculatus Olivier, 1791). Cossonus canaliculatus Fabricius, 1802 is a secondary homonym of the former and is replaced with Cossonus incisus. Salpingus fulvirostris (Fabricius, 1787) is reinstated as valid from synonymy under Salpingus planirostris (Fabricius, 1787), a primary homonym of Curculio planirostris Piller & Mitterpacher, 1783. The following new combinations are proposed: Brachysomus erinaceus (Fabricius, 1802) (from Curculio), Bronchus ferus (Gyllenhal, 1840) (from Hipporhinus), Bronchus glandifer (Fabricius, 1792) (from Curculio), Bronchus nivosus (Sparrman, 1785) (from Curculio), Bronchus sparrmani (Gyllenhal, 1833) (from Hipporhinus), Coelocephalapion atrirostre (Fabricius, 1802) (from Attelabus), Nerthops sticticus (Fabricius, 1777) (from Curculio), Piezotrachelus crotalariae (Fabricius, 1802) (from Attelabus), and Poropterus granulatus (Fabricius, 1802) (from Curculio). The junior homonym Brachycerus uva Fabricius, 1792 (non Sparrman, 1785) is replaced by Brachycerus fabricii nom. n. The following new synonymies are established: Brachycerus obesus (Fabricius, 1775) = Curculio scalaris Fabricius, 1777, syn. n., Brachyderes lusitanicus (Fabricius, 1781) = Curculio moratus Fabricius, 1798, syn. n., Brachypera (Brachypera) crinita (Boheman, 1834) = Curculio striatus Fabricius, 1787, syn. n., Brachysomus erinaceus (Fabricius, 1802) = Brachysomus villosulus (Germar, 1824), syn. n., Bronchus abruptecostatus (Gyllenhal, 1833) = Curculio spectrum Fabricius, 1802, syn. n., Bronchus nivosus (Sparrman, 1785) = Curculio recurvus Fabricius, 1802, syn. n., Camptorhinus tibialis (Sparrman, 1785) = Rhynchaenus alienatus Fabricius, 1802, syn. n., Coelocephalapion atrirostre (Fabricius, 1802) = Coelocephalapion luteirostre (Gerstäcker, 1854), syn. n., Cyrtoderes cristatus (DeGeer, 1778) (Tenebrionidae) = Brachycerus cristatus Fabricius, 1798, syn. n., Desmidophorus hebes (Fabricius, 1781) = Curculio tuberculatus Fabricius, 1792, syn. n., Donus salviae (Schrank, 1789) = Curculio denticornis Fabricius, 1798, syn. n., Exomias holosericeus (Fabricius, 1802) = Exomias chevrolati (Boheman, 1842), syn. n., Nerthops sticticus (Fabricius, 1777) = Nerthops guttatus (Olivier, 1807), syn. n., Phyllobius oblongus (Linnaeus, 1758) = Curculio mali Fabricius, 1782, syn. n., and Rhinocyllus conicus (Froelich, 1792) = Bruchus punctatus Fabricius, 1798, syn. n. Bronchus synthesys sp. n. is described to represent the concept of Hipporhinus spectrum sensu Marshall, 1904, a misidentification.
