E-mail: kajimura@agr.nagoya-u.ac.jp Abstract - In June 2005 Xylosandrus germanus (BLANDFORD, 1894), a new ambrosia beetle for Hungary was found close Nagymáté, County Baranya. The adults were excavated from freshly felled logs of Quercus and Tilia, and reared from these attacked trees in light eclector respec­tively. The prepared specimens are deposited at the Hungarian Natural History Museum (Coleoptera Collection) and at the Institute of Sylviculture and Forest Protection, University of West-Hungary. In its natural distribution X. germanus is considered as an important pest, while in Europe - where the species was introduced more than 60 years ago - no remarkable damage was reported. Genetic analyses - a comparison of the 400bp fragment of the mitochondrial COI gene - of Hungarian and German individuals were performed to confirm the species' sta­tus. The investigated populations can be considered identical (0.25% divergence, 2 haplotypes: GenBank accession numbers: HT-1 EF433438 and HT-2 EF433439). As outgroup for the anal­yses sequence data oïXylosandrus mancus (BLANDFORD, 1894) from the GenBank (AFI 87143) was used. Keywords - Xylosandrus germanus, new record, Hungary, mtDNA, COI. INTRODUCTION The investigation of the Hungarian scolytid fauna was rather extensive in the last decades. The last detailed description was published by ENDRÖDI (1959). The checklist of the Hungarian weevils (family Curculionidae) ­where, regarding the latest taxonomic rating, also the former family of the
