The specimens collected from five localities during the period from 2004 to 2022 were observed. As a result of this study, Jellyella eburnea was found to be new to the Korean fauna and three membraniporids were reviewed. Two species, Jellyella eburnea and Biflustra grandicella, were redescribed and illustrated with the collected specimens in this study. Membranipora perfragilis from Korea is changed into Biflustra grandicella. Jellyella eburnea is new to the Korean fauna and first reported outside subtropical and tropical seas of the South Pacific and Indo-Pacific Ocean. This fact proves that the seas in Korea are warming. Additionally, Biflustra crenulata reported from the West Sea, South Sea and Jejudo waters of Korea is synonymized into Biflustra okadai. Membranipora irregulata is transferred into the genus Biflustra. Five of Korean membraniporids, Biflustra grandicella, Biflustra irregulata, Biflustra okadai, Jellyella eburnea, and Jellyella tuberculata, are reported in the Korean fauna as a result of this study. The photos taken in the field and by Scanning Electron Microscopy of two species, Biflustra grandicella and Jellyella eburnea, are provided herein.
