New species and new records of exotic Scolytinae (Coleoptera, Curculionidae) in Europe

Abstract

Background Bark and ambrosia beetles (Coleoptera, Scolytinae) are amongst the most important woodboring insects introduced to Europe. During field investigations conducted between 2019 and 2021 in different countries and regions of Europe, many exotic species have been recorded providing new and relevant data. New information Dryoxylon onoharaense (Murayama, 1933) is recorded in Europe for the first time. Xyleborinus attenuatus (Blandford, 1894) is a species new to Italy, while Xylosandrus germanus (Blandford, 1894), Hypothenemus eruditus (Westwood, 1836) and Amasa sp. near A. truncata are new country records for Portugal. Cnestus mutilatus (Blandford, 1894), Phloeotribus liminaris (Harris, 1852) were collected in Italy and Amasa sp. near A. truncata was collected in France after the first discovery, confirming their establishment and their dispersal into new areas.
