On the true identity of Curculio pericarpius Linnaeus, 1758 (Coleoptera: Curculionidae)

Basing on the study of the type specimen of Curculio pericarpius Linnaeus, 1758 preserved in the Linnean Collection in London, and here designated as the lectotype, it was found that this name was misapplied to another close species of the genus Rhinoncus Schoenherr, 1825 starting from the Paykull 1792 misidentification. As a consequence, the following new synonymies are established: Rhinoncus pericarpius (Linnaeus, 1758) [= Curculio castor Fabricius, 1792, syn. n.; = Curculio interstitialis Reich, 1787, syn. n.; = Curculio scabratus Fabricius, 1792, syn. n.; = Curculio fruticulosus Herbst, 1795, syn. n.; = Curculio interstitialis Reich, 1797, syn. n.; = Rhynchaenus seniculus Gravenhorst, 1807, syn. n.; = Campylirhynchus quadricornis (Gyllenhal, 1813) sensu Dejean, 1821: 85 [misidentification] not Rhynchaenus quadricornis Gyllenhal, 1813, syn. n.; = Rhinoncus flavipes Stephens, 1831, syn. n.; = Rhinoncus rufipes Stephens, 1831, syn. n.; = Rhinoncus granulipennis Gyllenhal, 1837, syn. n.; = Rhinoncus pyrrhopus Boheman, 1845 sensu Hatch & Kincaid,1958: 20 [misidentification] not Rhinoncus pyrrhopus Boheman, 1845, syn. n.]; and Rhinoncus leucostigma (Marsham, 1802) [ = Curculio pericarpius Linnaeus, 1758 sensu Paykull, 1792 [misidentification] not Curculio pericarpius Linnaeus, 1758, syn. n.; = Cryptorhis herbstii Billberg, 1820: 43 [replacement name for Curculio pericarpius Linnaeus sensu Paykull, 1792], syn. n.; = Rhinoncus spartii Stephens, 1831, syn. n.; = Rhinoncus sanguinipes Reitter, 1916, syn. n.; = Rhinoncus pericarpius ssp. montanus Hoffmann, 1960, syn. n.]. Lectotypes are designated for Curculio pericarpius Linnaeus, 1758 and Curculio leucostigma Marsham, 1802. A neotype is selected for Curculio interstitialis Reich, 1797
