Abstract

A new species, Ophiomonas shinseimaruae, is described based on five specimens collected from deep water settings, southeast of Cape Erimo, Hokkaido, Japan. Ophiomonas shinseimaruae sp. n. is distinguished from other congeners based on the following characters: elongate semi-circular and separated radial shields; triangular oral shields; flat and broad tentacle scales on the second tentacle pore; octagonal dorsal arm plates, approximately three times wider than long on proximal portion of the arm; and three arm spines present proximally on the arm. This is the first record of the genus Ophiomonas from Japanese waters. The COI nucleotide sequence for Ophiomonas shinseimaruae sp. n. is provided.
