The first occurrence of the genus Hornera (Bryozoa, Cyclostomata) is reported from waters around Jeju Island, Korean Peninsula. Hornera jeongsangi n. sp. differs from all known species of the genus Hornera in having very prominent spiny protrusions around the autozooidal apertures, which are not arranged in fascicles, the gonozooidal ooeciopore facing frontally and nonporous zooidal walls around the ooeciopore.
