The new species is considered a simultaneous hermaphrodite, but no brooding embryos were found in any of the specimens collected in this study. This species is unique in the absence of ciliation in the anteriormost chaetigers. <jats:italic>Rhynchospio aciliata<\/jats:italic><jats:bold>sp. nov.<\/jats:bold> is morphologically most similar to <jats:italic>Rhynchospio foliosa<\/jats:italic> Imajima, 1991 from Japan in having an elevation on the prostomium, conspicuously large and foliaceous branchiae, and intersegmental lateral pouches. However, the new species differs from the latter by the following characteristics: (1) large and lanceolate notopodial postchaetal lamellae of chaetiger 1, (2) transverse ciliated bands and ciliation on the inner branchiae absent in anteriormost chaetigers, and (3) pygidium with one pair of ventral cirri and numerous elongated dorsolateral cirri. Detailed description and illustrations of the new species are provided with molecular information on mitochondrial cytochrome c oxidase subunit I (COI), 16S ribosomal DNA (rDNA), nuclear 18S rDNA, and 28S rDNA.<\/jats:p>","DOI":"10.3897\/zookeys.1100.80077","type":"journal-article","created":{"date-parts":[[2022,5,16]],"date-time":"2022-05-16T14:16:57Z","timestamp":1652710617000},"page":"191-205","source":"Crossref","is-referenced-by-count":2,"title":["\ufeffRhynchospio aciliata sp. nov., a new spionid species (Annelida, Spionidae) from the Korea Strait"],"prefix":"10.3897","volume":"1100","author":[{"given":"Geon Hyeok","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gi-Sik","family":"Min","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2022,5,16]]},"reference":[{"key":"80077_B1","doi-asserted-by":"publisher","DOI":"10.3897\/zookeys.1015.54387"},{"key":"80077_B2","first-page":"81","article-title":"Family Spionidae Grube, 1850.
