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

Two new species of the family Aoridae, one from the genus <i>Aoroides</i> Walker, 1898, and other from the genus <i>Grandidierella</i> Coutière, 1904, are reported from Korean waters. <i>Aoroidesgracilicrus</i> <b>sp. nov.</b> is similar to <i>A.longimerus</i> in having numerous plumose setae on the basis and carpus of gnathopod 1. However, the new species can be distinguished from <i>A.longimerus</i> by the numerous plumose setae on the bases of pereopods 3 and 4 and the slender basis of pereopod 7. <i>Grandidierellanaroensis</i> <b>sp. nov.</b> is morphologically most similar to <i>G.pseudosakaensis</i>. 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.
