Sternaspid annelids are common and often abundant in the world ocean. They are usually corrected in sandy or muddy bottoms at a variety of depths. Sternaspid annelids are now known as characterized by the morphology of ventro-caudal shield, papillae of the body surface and posterior shield chaetae. Although sternaspid annelids recorded from Japan have been called as Sternsapis scutata since 1930s works, we could record two genera and seven species from Enshu-Nada, Kumano-Nada and off Sendai, East coast of Japan: Sternsapis scutata sensu strict, S. affinis, S. islandica, S. thalassemoides, S. costata, Petersenaspis capillata, and P. palpallatoci. Sternaspis has seven abdominal chaetigers and shield with radial ribs, concentric line or both. Petesenaspis has eight abdominal chaetigers and shield with poorly distinct ribs but no concentric line.
