The family Ptiliidae, also called featherwing beetle because of their remarkable feather-like hind wings, is group of the smallest beetles, with their body size generally about 1 mm long. Although more than 1,000 valid ptiliids within approximately 100 genera are distributed worldwide, this family remains one of the least understood beetle groups in Korea. In this study, we introduce 13 known Korean ptiliids species within seven genera and additional some unknown species. All available information about Korean ptiliids, including their natural histories, distributional data, and diagnostic characters are provided.
