Abstract
A new species of photid amphipod, Podoceropsis nanseiae, is described from Kagoshima Bay, Japan. The present new species can be distinguished from all the congeners in having clusters of robust setae on the male gnathopod 2 basis. This species resembles Gammaropsis laevipalmata Ren, 1992, however can be distinguished from G. laevipalmata by the presence of small accessory flagellum in antenna 1, the size of eyes, the shape of palmer margin of male gnathopod 2, and the clusters of robust setae on the male gnathopod 2 basis. The closely related species G. laevipalmata should be transferred to the genus Podoceropsis. Additionally, a partial DNA sequence of the mitochondrial cytochrome c oxidase subunit I (COI) was determined from the type specimens of P. nanseiae sp. nov. for future taxonomic studies.
