Four cyclostomatous bryozoans from Korea belong to the genera Bicrisia, Nevianipora, Tubulipora and Crisia are described here for the first time. Of which, Bicrisia erecta Mawatari & Mawatari, 1973, Nevianopora pulcherrima (Kirkpatrick, 1890) and Tubulipora similis Liu in Liu, Yin & Ma, 2001 are newly added to the Korean bryozoan fauna, and Crisia spissus n. sp. is new to science. These species in this study are identified based on three features, which are its pseudopore, gonozooids and ooeciostomes. Two genera, Bicrisia and Nevianopora, are new to the Korean bryozoan fauna. As a result of this study, nine Korean cyclostomatous bryozoans in seven genera, five families are reported.

This paper describes three cyclostomatous bryozoans belonging to the family Tubuliporidae Johnston, 1838 from Korean waters. It was carried out with the materials which were collected from three localities during the period from 2011 to 2017. As a result of the present study, three cyclostomatous bryozoans, Exidmonea intercalata Liu, Liu & Zágoršek, 2019, Qingdaoella conaria Liu, Liu & Zágoršek, 2019 and Tubulipora perforata Liu, Liu & Zágoršek, 2019 are newly added to the Korean bryozoan fauna. Furthermore, two genera, Exidmonea David, Mongereau & Pouyet, 1972 and Qingdaoella Liu, Liu & Zágoršek, 2019, are reported for the first time from Korea. These species were previously known only in Qingdao, China, which belongs to the temperate zone influenced by the Kuroshio Current. Descriptions and illustrations of the three cyclostomatous bryozoans using Scanning Electron Microscopy are provided in this study.

For the systematic study of the bryozoans in Cheju-do, the present study was done with the materials collected from 13 localities of Cheju-do during the period from 1965 to 1985. As a result, 52 species were reported, bringing total number of species known from Cheju-do to 74. Of them eleven species were new to Korean fauna. They were as follows: Tubulipora pulchra, Ellisina canui, Labioporella sinuosa, Mucropetraliella mucroaviculata, Emballotheca pacifica, Hippomenella spatulata, Microporella cribrosa, Smittina raigii, Smittoidea prolifica, Parasmittina triangularis and Escharoides excavata.

The bryozoan assemblage from Seogwipo Formation in Jejudo yielded 33 taxa, including seven cyclostomes and 26 cheilostomes. It is the first fossil bryozoans described from the entire Korean peninsula. Five species, Callopora inermis, Tegella horrida, Celleporaria reflexa, Porella rotundirostris, and Rhynchozoon obliquimandibulatum, are new to the Korean bryozoan fauna as both in the Recent and fossil records. Tegella horrida, Celleporella reflexa, Porella donoghueorum, and Leischara subgracilis are notably cold-water species. This suggests that the Seogwipo Formation was primarily deposited in shallow water environment, subject to changesinfluenced by warm-water masses and temporarily impacted by cold currents. Only 33 species from the Seogwipo Formation in Korea, are very poor because the Seogwipo Formation is the only Pleistocene marine deposit in the Korean Peninsula. Eight species previously unknown as fossils worldwide, Tubulipora perforata, Puellina paracaesia, Reginella multipora, Celleporella reflexa, Exochella cryptodontia, Suhius cf. rubescentis, Cheiloporina cf. haddoni, and Jodoella koreensis are found in the Seogwipo Formation. This study is meaningful as it reports the first fossil assemblage of bryozoans from the Korean peninsula.
