Six phytal harpacticoid species of the genus Porcellidium are recorded from 22 algal species in the eastern (Sea of Japan) and southern (Korea Strait) coast of Korea. Among these six species, Porcellidium ofunatense Harris and Iwasaki and Porcelliadium gamoi (Harris and Iwasaki) are recorded as new to Korean fauna Other four species are described as new to science: Porcellidium bipartitum n. sp. Found from a single algal species, Porcellidium wandoensis n sp. from ten algal species, Porcellidium acutum n. sp from five algal species, and Porcellidium brevicacum n sp. from two algal species. It is found that the associations between the species of Procellidium and macroalgae reveal weak specificities.
