Abstract
    Two new species of the genus Orchomenella G. O. Sars, 1890 from South Korea are described here in detail. Orchomenella paucisetigera sp. nov. is characterized by an irregular and serrated palmar margin of gnathopod 1, non-serrated posterior margins of pleonal epimera 2-3, a more produced posteroventral corner of pleonal epimeron 3, and scarcely setose uropods 1-2. Orchomenella rugosa sp. nov. is easily discriminated from other congeners by its proximally slender basis and irregular palmar margin of gnathopod 1, marginal wrinkles ventrally of coxa 4, and the serrations and shapes of pleonal epimera and urosomite 1.
