| Abstract |
A new species of eriopisid amphipod, Victoriopisa satsumaensis, is described from Kagoshima Prefecture, southern Japan. The new species is distinguished from its congeners by the presence of eyes, the absence of a distodorsal tuft of long setae on peduncular article 2 of antenna 1, and the shape of the palmar margin and the dactylus of gnathopod 2. The new species is most similar to V. nhatrangensis Marin and Palatov, 2022, which was recently described from Vietnam, but differs in having (1) more numerous short setae along the palmar margin of gnathopod 1, (2) 2 projections on the palmar margin of gnathopod 2, (3) a shallower median excavation on the posterior margin of gnathopod 2 dactylus, (4) several robust setae on the anterior margin of pereopods 5 and 6 carpi, and (5) more numerous distal setae on article 2 of uropod 3 outer ramus. Additionally, partial sequences of mitochondrial cytochrome c oxidase subunit I and histone H3 were determined from the type specimens of V. satsumaensis for DNA barcoding and future taxonomic studies. |
