Eocuma orbiculatum sp. nov. (Crustacea, Cumacea, Bodotriidae) from Korean waters

Abstract

A new species of Cumacea belonging to the genus Eocuma Marcusen was collected from the South Sea of Korea. This new species resembles E. amakusense Gamô, E. hilgendorfi Marcusen, and E. latum Calman in having a pair of well-developed dorso-lateral carinae on the flat carapace and similar setae pattern on the telson. The new species, however, is easily distinguished from its congeners by the pattern of dorso-lateral carina and lacking lateral horns on the carapace. The adult male of this new species is fully described. A key to the Korean Eocuma species is also provided.
