Of these, the genus Nipponomysis including N. lingvura, N. ornata, and N. imparis, and Acanthomysis nakazatoi were newly recorded from the Korean waters. Morphological descriptions and taxonomic key to species were given. The present study reports that 45 species belonging to 15 genera from the Korean waters have been recorded.
