The family Bostrichidae contains 9 subfamily and about 580 species. Almost all have adapted to xylophagy, living mainly in sapwood rich in cellulose and many species are considered as serious and onerous technical pests - with increasing export of wooden articles and containers increases also the frequency of introduction of these beetles to various parts of the world, including those of temperate or cold climate (Borowski and Wegrzynowicz, 2007). In Korea, Up to days, 7 species of 5 genera of the family Bostrichidae have been recorded. We added two species, Dinoderus speculifer Lesne, 1895 and Xylothrips pekinensis (Lesne, 1902 - Comb. nov.). And Xylothrips cathaicus Reichardt, 1966 is synonymized with Xylothrips pekineisns (Lesne, 1902 - Syn. nov.). Borowski and Wegrzynowicz (2008) added Xylothrips pekinensis to the Japanese fauna with a photo and mentioned on the possibility of the distribution in the Korean peninsula, but this species had been already recorded to the Japanese fauna by Iwata and Kusakabe (2002).
