Nomenclatural changes in the genus Xylothrips Lesne, 1901 (Coleoptera, Bostrichidae, Xyloperthini)

The paper contains informations on the descriptions and analyse of various authors’ opinions as to the ocurrence and systematic position of species belonging to the genus Xylothrips. As the result of the analysis Calophagus has been downgraded to a subgenus of Xylothrips – Xylothrips (Calophagus) n. comb. – and Xylothrips geffroyi (n. syn.) synonymized with X. religiosus. At the end a key to the identification of all known species of Xylothrips is presented, together with a catalogue and maps showing the geographical distribution of particular species.
