On the type specimen of Otiorhynchus (Dodecastichus) ambrosii Bertolini, with a catalogue of Dodecastichus (Coleoptera: Curculionidae)

Abstract

Study of the type specimen of Otiorhynchus ambrosii Bertolini, 1893 allowed to reinstate the synonymy: Dodecastichus mastix (Olivier, 1807) [= Otiorhynchus (Dodecastichus) ambrosii Bertolini, 1893; syn. n.]. As a consequence, the following synonymy is also established: Dodecastichus consentaneus (Boheman, 1842) [= Otiorhynchus (Dodecastichus) consentaneus alticola A. Solari & F. Solari, 1915; syn. n.]. A revised list of Dodecastichus Stierlin, 1861 is also drawn up to correct some errors in the latest 2013 catalogue, to include the revised synonymies above, and additional data on all the species of the genus. The alternative original spelling Dodecastichus oligostictus (J. Müller, 1946) is selected over Dodecastichus oligolepis (J. Müller, 1946), both used in the description of this species.
