Eight New Records of Siphonophores (Cnidaria: Hydrozoa) in Korean Waters

Taxonomical research on siphonophores is lacking despite their high biodiversity. We collected in Jeju and the southern coasts of Korea conducted morphological redescriptions using multi-focus stacked digital images. As a result, we revealed eight unrecorded (Abyla haeckeli, Ceratocymba leuckartii, Bassia bassensis, Dimophyes arctica, Lensia subtilis, subtiloides, Muggiaea atlantica, Nanomia bijuga). Six genera, excluding Muggiaea, were reported for first time Korean waters, subfamily Abylinae, to which Abyla haeckeli leuckartii belong, was also recorded Korea. The distributions habitats these species summarized, with most having cosmopolitan but variations individual size depending environmental conditions. Phylogenetic analysis based mtCOI each family. Finally, updated list waters include 3 suborders, 5 families, subfamilies, 14 21 species. Our findings constitute baseline data further siphonophores.
