A new species of harpacticoid copepod, Halectinosoma foveolata, was described from sandy sediments on several intertidal areas of Korea. This new species is mostly similar to H. dimorphum Coull, 1970, but differs from the latter by the following characteristics combined: (1) the third segment of antennule is longest; (2) the first exopodal segment of antenna has a row of spinules; (3) the mandibular gnathobase is composed of chitinous teeth without dorsal seta; (4) the female P5 has an incomplete boundary between the exopod and the baseoendopod; (5) the female P5 baseoendopod has two rows of spinules. We also discuss the state of H. arenicola sensu Itô (1973), reported from the Japanese coast, which is considered here a synonym with the new species.
