described from Russia was examined here, and as a result, important morphological differences were detected between Korean material and the Russian type specimen. The characteristics differing between the Korean specimens and the type material are as follows. In male gnathopod 1, the basis is expanded anterodistally in the Korean specimens, while it is narrow and straight in the type material. The length ratios of carpus and propodus of the Korean and Russian specimens are 1.3 and 1.8, respectively. The shape of gnathopod 1 carpus is more rectangular in the Russian material than in the Korean sample. The propodus of male gnathopod 2 is longer and more rectangular in the Russian material compared to the Korean sample. The apical margin of the telson is round in the Korean specimen, while it is subacute in the Russian type material. Based on the morphological differences mentioned above, the Korean material has been assigned to a new species,
