摘要

An examination of major collections of bark-beetles from Leningrad Province of Russia has revealed 11 species new to the region: Carphoborus rossicus Sem., Scolytus intricatus Ratz., S. laevis Chap., S. multistriatus Marsh., Pityogenes trepanatus Nordl., Pityokteines spinidens Reitt., Ips amitinus Eichh., I. cembrae Heer, Taphrorychus villifrons Duf., Trypodendron laeve Egg., and Trypophloeus palmi Hansen. The verified list of bark beetles from Leningrad Province includes now 68 species. Old records of some bark-beetle species from this region, which cannot be verified nowadays, are specially discussed. The area under study is the northernmost region of Europe from which two species of bark beetles, Scolytus laevis and Pityogenes trepanatus, havebeen recorded. Several species of bark beetles, including Hylastes ater Pk., are excluded from the regional faunal list. The ambrosia beetles Trypodendron laeve and T. proximum Niis. are proved to be separate species. The biology and distributions of several bark-beetle species are discussed in comparison with data from neighboring regions.
