During surveys conducted in the woods of the Ticino Park in Lombardy, northern Italy, we recorded a North American Phloeotribine scolytid, new to the fauna of Europe, Phloeotribus liminaris (Harris), the "Peach Bark Beetle". High densities of wintering refuges and adults were observed on Prunus serotina Ehrh., its typical host tree in the natural distribution area. P. serotina was introduced into Italy from North America and is now a very diffuse infestant in various lowland woods of northern Italy. This is the first record of the Peach Bark Beetle outside of its natural distribution area where it caused serious damage to P. serotina, an important source of valuable wood, and other forest and fruit Prunus, especially P. persica. The habitat where the bark beetle was found consists of riparian lowland woods dominated by Quercus robur L., Fraxinus excelsior L., Populus nigra L., Salix alba L. and Pinus sylvestris L., associated with the introduced species Robinia pseudoacada L., Ailanthus altissima (Mill.) and Prunus serotina. To facilitate the identification of the species and the recognition of new infestations, the Authors provide a brief description with original drawings of both P. liminaris and the nearly related P. scarabaeoides (Bernard) and with an identification key with brief bioecological notes. Potential risk of the diffusion of P. liminaris in Italy is also discussed.
