Abstract

A new brackish-water species of melitid amphipod,Melitachoshigawaensis, from the Choshigawa River, Mie Prefecture, Japan, is named and described.Melitachoshigawaensissp. n.is distinguished from the most similarM.shimizui(Uéno, 1940) by having an elongate and weakly arched male uropod 3, and a deep and strongly hooked anterior lobe of the coxa on the female’s pereopod 6. Nucleotide sequences of the mitochondrial cytochromecoxidase subunit I (COI) ofM.choshigawaensisandM.shimizuisupport divergence at the species level. A key to the Japanese species ofMelitais provided.
