Abstract - A new Otiorhynchus (Lixorrhynchus) Reitter, 1914 from Baronia, central-eastern Sardinia (Coleoptera, Curculionidae) - Otiorhynchus (Lixorrhynchus) gigantium n. sp., from hills south of Mount Albo (Baronia, CE Sardinia) is herein described. For some characteristics, the new species is close to O. (L.) consortii Magrini, Abbazzi & Cirocchi, 2001, endemic to Sardinia in the area of Lula, from which however is well distinguished by its vestigial eyes, the shorter pronotum, narrower at base and with sparser punctation, the less prominent pterygia, the dorsal carinae of the rostrum converging posteriorly rather than parallel, the larger and sharper spines of femora, the more massive and stout aedeagus in lateral view, the spermatheca with thinner, less curved cornus, and, above all, the basal armor of the internal sac of the aedeagus clearly different in ventral view. The updated sizes, on the basis of new records, of O. (L.) consortii are also given.
