Based on samples collected from the Korean Exclusive Economic Zone (EEZ) during an investigation of fishery resources by the National Fisheries Research and Development Institute (NFRDI) from 2002 to 2010, alongside some supplemental material, six species of the genus $Plesionika$ are identified: $P.$ $izumiae$ Omori, 1971, $P.$ $ortmanni$ Doflein, 1902, $P.$ $grandis$ Doflein, 1902, $P.$ $lophotes$ Chace, 1985, $P.$ $narval$ (Fabricius, 1787), and $P.$ $orientalis$ Chace, 1985. Of these, the last four species are new to Korean marine fauna. The distributional range of $P.$ $narval$ extends to the East China Sea off Jeju Island. Excluding $P.$ $izumiae$ and $P.$ $ortmanni$, the other four species are relatively rare in the seas around Korea. They are described and illustrated with color photographs. A key to the Korean species of $Plesionika$ is also presented.
