Currently, the genus <i>Stylicletodes</i> Lang, 1936, which is known to occur in subtidal sediments, has not been reported in this area so far. During surveys on the subtidal meiofauna, we found a new species of <i>Stylicletodes</i> from several subtidal muddy sediments in the Yellow Sea and South Sea.<h4>New information</h4>In this study, we describe both sexes of a new species of <i>Stylicletodes</i> collected from the Yellow Sea and South Sea of Korea. <i>Stylicletodestrifidus</i> sp. nov. differs from its congeners in the following characteristics: the trifid rostrum, relative length ratio of the endopods to exopods on legs 1-4, reduced armature formulae on leBiodiversity data journale90590https://www.ebi.ac.uk/biostudies/studies/S-EPMC9836576biostudies-literatureA new species of the genus <i>Stylicletodes</i> Lang, 1936 (Copepoda, Harpacticoida, Cletodidae) from South Korea.PMC9836576Cho KLee JKim JGfalseA new species of the genus <i>Stylicletodes</i> Lang, 1936 (Copepoda, Harpacticoida, Cletodidae) from South Korea.<h4>Background</h4>Marine benthic harpacticoid copepods are poorly known in Korea due to the difficulty in obtaining specimens.
