Abstract
In 2021, during a survey of cnidarian fauna around Geomundo located in the Dadohaehaesang National Park in the South Sea, complete pinnated hydroid colonies attaching on vertical rocky surface at depth of 45 m were collected by SCUBA diving. Through taxonomic examination, unrecorded species, Sertularella acutidentata Billard, 1919, is newly added to the hydrozoan fauna of Korea. Recently, taxonomic position of the genus Sertularella has been relocated into the new family Sertularellidae Maronna et al., 2016 and six species from Korean waters have been synonymized or transferred to new genera. Thus, a total of 17 species belonging to genus Sertularella, including the species reported in this study, have been reported in Korean waters so far.
