We found three fouling bryozoans from the materials collected from seven localities (ports, yacht marina, intertidal and subtidal zones) in the coastal seas of South Korea from 2003 to 2021. These three species, Thalamoporella californica (Levinsen, 1909), Scruparia ambigua (d'Orbigny, 1841), and Tricellaria inopinata d'Hondt and Occhipinti Ambrogi, 1985, and one genus Scruparia Oken, 1815 are newly added to the Korean bryozoan fauna. Of the three species, Scruparia ambigua and Tricellaria inopinata are cosmopolitan or widespread, and Thalamoporella californica is from the East Pacific Ocean in tropical/temperate water. It seems that some of the previously reported T. occidentalis in Korea have a high probability of being T. inopinata. In this study, some Tricellaria occidentalis reported by Seo (2005) are synonymized into T. inopinata. A total of 77 species of fouling bryozoans has been reported in Korea, with three new bryozoans resulting from this study. Descriptions and illustrations of the three fouling bryozoans using scanning electron microscopy are provided in this study.
