Summary:Two new records of spionid polychaetes, Prionospio pulchra Imajima, 1990 and Scolelepis (Scolelepis) sagittaria Imajima, 1992, collected from Korean waters are reported here with detailed descriptions and illustrations. Prionospio pulchra can be distinguished from its relatives by remarkably long and apinnate branchiae, the first chaetiger with notopodial chaetae, and the presence of ventral sabre chaetae. Scolelepis (Scolelepis) sagittaria is characterized by a sagittate prostomium, an occipital tentacle, and bi- or tridentate hooded hooks. In this paper, photographs of scanning electron microscopy for characteristic features of each species are presented. Keys to Prionospio and Scolelepis species from Korean waters are also provided.
