Four homalotine species-Anomognathus armatus (Sharp), Heterota onorum Maruyama, Neosilusa ceylonica (Kraatz), and Silusa lanuginosa Sharp-and three genera-Anomognathus Solier, Neosilusa Cameron, Silusa Erichson-are identified for the first time in Korea. The tribe Homalotini can be distinguished from other related tribes by the combination of the following characters: tarsal formula 4-4-5; mandible with patch or rows of denticles in ventral molar region; base of medial setae of prementum very close together, setal insertions in contact in many, setae displaced one behind the other in some; medial pseudopore field of prementum very narrow in many.
