Two new species of the family Aoridae (Crustacea, Malacostraca, Amphipoda) from Korean waters

Abstract

Two new species of the family Aoridae, one from the genus Aoroides Walker, 1898, and other from the genus Grandidierella Coutière, 1904, are reported from Korean waters. Aoroides gracilicrus sp. nov. is similar to A. longimerus in having numerous plumose setae on the basis and carpus of gnathopod 1. However, the new species can be distinguished from A. longimerus by the numerous plumose setae on the bases of pereopods 3 and 4 and the slender basis of pereopod 7. Grandidierella naroensis sp. nov. is morphologically most similar to G. pseudosakaensis. However, the new species can be distinguished by the presence of small distal and proximal processes and a large middle process on the carpus of gnathopod 1, and the subovate propodus of gnathopod 1. Both new species are illustrated and compared to related species. A key to species in the family Aoridae from Korean waters is also provided.
