title: A new species of the genus Rhinoecetes Just, 1983 (Crustacea: Amphipoda: Ischyroceridae) from Japan.
abstract: A new species of ischyrocerid amphipods, Rhinoecetes spinicaudus sp. nov., is described from Nabeta Bay, southeast coast of Izu Peninsula, central Japan. This new species can be distinguished from the other congeners by the presence of spinulation on the lateral margins of uropod I rami, row of small robust setae on uropod II ramus, and single robust seta on uropod III ramus. More detailed distinguishing characters from R. albomaculosus are also discussed. This is the first record of the genus Rhinoecetes from Japan. Key to all the species of Rhinoecetes is provided.
