The present census on freshwater bryozoans in the Han River, Geum River and in lentic water bodies in Gangwon Province revealed three gymnolaemate species. Two of them-Hislopia prolixa Hirose and Mawatari, 2011 and Victorella pavida Saville Kent, 1870 were recorded for the first time from South Korea. Paludicella articulata (Ehrenberg, 1831), on the other hand, had already been documented from a few sites since 1941. The bryozoans, all belonging to the order of Ctenostomata, were found on a variety of substrates in freshwater (H. prolixa and P. articulata) and brackish habitats (V. pavida). Hislopia prolixa had recently been established as a new species and this is the first record for an occurrence outside of Japan, where it had been newly described from Lake Biwa and nearby satellite lakes.

A ctenostomatous bryozoan, Bantariella bocki is reported from Jejudo Island of South Korea. This is the first report from Korean waters. Each zooid is produced from each kenozooid which arranged in two and originated opposite each other at intervals of about 0.64 mm along the stolon. B. bocki collected from black corals is considered to be a invasive species introduced from Bonin Islands located in the subtropical waters. The redescription, some distributional remarks and illustrations of B. bocki are provided.
