Coléoptères de Corse : nouveaux signalements et observations remarquables

Abstract

Coleoptera from Corsica: new records and other notable observations. Based on the material collected in Corsica during the scientific explorations La Planète Revisitée en Corse 2019-2021, a commented list of 56 rare, endemic, poorly documented and/or new Coleoptera for the Corsican fauna is presented. DNA sequences (CO1) are associated to 25 of these species. The following two species are new to the French fauna: the Ptinidae Stagetus sardous (Reitter, 1915) and the Thymalidae (formerly Trogossitidae) Thymalus punicus Franz, 1981. The following 17 species are reported for the first time in Corsica: Brachinus nigricornis Gebler, 1830, and Trechus obtusus Erichson, 1837 (Carabidae); Hypocaccus (Nessus) ascendens (Reichardt, 1932) and Plegaderus (Plegaderus) caesus (Herbst, 1791) (Histeridae); Paederus balcanicus Koch, 1938 (Staphylinidae); Coraebus elatus (Fabricius, 1787) (Buprestidae); Dorcatoma punctulata Mulsant & Rey, 1864 (Ptinidae); Tillus elongatus (Linnaeus, 1758) (Cleridae); Arthrolips fasciata (Erichson, 1842) (Corylophidae); Corticaria crenulata (Gyllenhal, 1827) (Latridiidae); Mordellistena reichei Emery, 1876 (Mordellidae); Pyrochroa coccinea (Linnaeus, 1761) (Pyrochroidae); Vanonus brevicornis (Perris, 1869) (Aderidae); Saperda populnea (Linnaeus, 1758) (Cerambycidae); Donacia impressa Paykull, 1799, et Crepidodera fulvicornis (Fabricius, 1792) (Chrysomelidae); Polydrusus xanthopus Gyllenhal, 1834 (Curculionidae). Finally, based on morphology and DNA barcodes Purpuricenus kaehleri corsicus Vartanis, 2018, is considered a junior synonym of Purpuricenus kaehleri kaehleri (Linnaeus, 1758).
