A new cirratulid species, , is described from the intertidal habitats of the eastern coast of South Korea. The new species is closely related to (Moore, 1904) from southern California based on morphological similarity of the branchial and tentacular finalents and the noto- and neuropodial spines. However, differs from the latter based on the following characteristics: 1) evenly divided peristomium into three annulations; 2) 2-4 neuropodial spines originating in the posterior chaetigers alternated by a few capillaries; and 3) complete shift in branchial finalents located about one-third between the notopodium and the dorsal midline. The new species has a methyl green staining pattern (MGSP) distinct from other species. Detailed description and illustrations of the new species are provided with molecular information based on the partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA (16S). This study also includes a key and discussion of known species from East Asia.
一种新的蛰龙介科物种， ，是从韩国东海岸的潮间带栖息地描述的。基于鳃和触手终末的形态相似性以及背叶和腹叶刚毛，该新物种与来自南加州的 （摩尔，1904年）密切相关。然而， 与后者的不同之处在于以下特征：1）围口节均匀地分为三个环；2）2 - 4根腹叶刚毛起源于后体节，中间夹杂一些毛细管；3）鳃终末完全移位，位于背叶和背中线之间约三分之一处。新物种具有与其他 物种不同的甲基绿染色模式（MGSP）。基于线粒体细胞色素c氧化酶亚基I（COI）和16S核糖体RNA（16S）的部分序列，提供了新物种的详细描述、图示以及分子信息。本研究还包括东亚已知 物种的检索表和讨论。
