Up to days, 31 species of 7 genera of the tribe Xyleborini have been recorded from Korean peninsula. We have collected the bark beetles with Malaise traps from 2007 to 2009 in the central part of the Korean peninsula. As a result of this study, we report 2 species, Xyleborus japonicus Nobuchi, 1981 and X. pelliculosus Eichhoff, 1878, for the first time from Korea with brief descriptions and illustrations of diagnostic characters.
