The tribe Erythropini Hansen, 1910 belonging to the subfamily Mysinae Haworth, 1825, is one of the peculiar groups mainly found in the pelagic or deep sea. Of these, the genus $Erythrops$ G.O. Sars, 1869 including two mysids, $Erythrops$ $minuta$ Hansen, 1910 and $Erythrops$ $nana$ W. Tattersall, 1922, is reported for the first time from Korea. The genus is easily distinguished from other genera by the antennal scale with a terminal strong spine, the carpus of third to eighth thoracopods divided into the propodus by an oblique articulation, and the trapezial telson. The morphological descriptions and the illustrations of these species are given with photographs. As a result of this study, 49 species of mysids including these two species are now recorded in the Korean fauna.
