Abstract

Twelve species of cyclopoid copepods, including two new genera and ten new species, associated with polychaetes are described from Korea. The new taxa comprise Petalocopus planus n. gen. n. sp. in the Clausidiidae, Rhodinicola exilis n. sp. in the Clausiidae, Gastrodelphys vadicola n. sp. in the Gastrodelphyidae, Polyankylis estivalis n. sp. in the Polyankyliidae, Pentakela cylindrica n. gen. n. sp., Pseudanthessius oporinus n. sp. and P. petilus n. sp. in the Pseudanthessiidae, and Myxomolgus buanensis n. sp., M. dokdoicus n. sp. and Serpuliphilus antennatus n. sp. in the Sabelliphilidae. As characteristic features of the new genera, Petalocopus n. gen. has a pair of pedunculate suckers on the terminal segment of the antenna and an enlarged posterodistal seta on the second segment of antennule, and Pentakela n. gen. has five strong hooks on distal segments of antenna, three-segmented exopod and two-segmented endopod in legs 1 and 2, and one-segmented exopod and a lobate, rudimentary endopod in legs 3 and 4. The male of Maxilliclausia propria Kim, 2014 of the Clausiidae is recorded for the first time. Nereicola ovata Keferstein, 1863 known previously only in European waters is redescribed based on a newly collected female specimen from Korea.
