Pissodes irroratus Reitter, 1899 (Coleoptera, Curculionidae, Molytinae) is a species from east Russia newly discovered in Europe in various locali-ties in the Alps (France, Switzerland, and Italy). We provide here a description of morphological characters and molecular data (mitochondrial standard barcode gene) for this species. We also give diagnostic characters to distinguish this species from its closest relative, Pissodes harcyniae (Herbst, 1795), and other west palearctic species of the genus.
