Abstract - Description of Archarius ziliolii, new species from Italy and Switzerland related to A. crux (Fabricius) (Coleoptera, Curculionidae) - Archarius ziliolii n. sp. is described from northern and central Italy and southern Switzerland. This species is closely related to A. crux (Fabricius, 1777) (formerly Curculio), from which it differs by the sparser white scales of the dorsal vestiture, which form a thinner and shorter vitta at the sides of the pronotum and a thinner and shorter transverse band at the middle of elytra; moreover, in the male of A. ziliolii the uncus of fore tibiae is stouter and angularly curved, whereas the aedeagus is parallel-sided instead of being enlarged from the base to the apical third and further abruptly constricted. In addition, the lectotypes of Curculio crux Fabricius, 1777 and Balaninus rhaeticus Fuchs, 1862 are designated, and the synonymies of the latter taxon and Balaninus crucifer Fuchs, 1862 with A. crux (Fabricius) are confirmed.
