A species of marine limnodriloidine oligochaete, Thalassodrilides cf. brianiErseus, 1992, is recorded from gravelly sand sediments of the subtidal zone in Ehime Prefecture, Japan. The present material agrees with the original description of T. briani, which was first found at Hong Kong, with the exception that the copulatory sacs are oval; not slender. Despite the lack of genetic data for the Hong Kong population, we conclude that the Japanese specimens are conspecific with it, or at least very closely related, based on morphological considerations. This is the first record of the genus ThalassodrilidesBrinkhurst and Baker, 1979in Japan. The phylogenetic relationships between T. cf. briani and three other species of Thalassodrilides are estimated, based on partial DNA sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the complete nuclear ribosomal Internal Transcribed Spacer (ITS) region, using two members of the closely related genus Doliodrilus Erseus, 1984 as outgroups. The genetic analysis shows that T. cf. briani is a species delimited by both mitochondrial and nuclear data, and clearly separated from at least its closely related congeners in the Northwest Atlantic (Caribbean and adjacent areas).
