Two newly recorded opheliid polychaetes, Armandia amakusaensis Saito, Tamaki and Imajima, 2000 and Polyophthalmus qingdaoensis Purschke, Ding and $M{\ddot{u}}ller$, 1995, from Korean waters are reported with the descriptions and illustrations. Armandia amakusaensis can be clearly distinguished from its congeners by the following characteristics: the prostomium has 2 or 3 subdermal eyespots; total number of setigers are 29; the branchiae are present on the setigers from the setiger 2 to the second or third from the last setiger; the lateral eyespots beginning from the setiger 7 are composed of 11 pairs; the anal funnel has 8~11 papillae and a long cirrus. Polyophthalmus qingdaoensis has the distinguishable characteristics from its relatives as follows: the prostomium has a brain bearing dark pigment-spots; the lateral eyespots are distinct; the body has only dark pigment-streaks on dorsal side. We also provide the keys for distinguishing the species of the genera Armandia and Polyophthalmus from Korean waters.

The goniadid species, Glycinde bonhourei Gravier, 1904, is newly reported with the description and illustration from Korean waters. Our Korean materials of G. bonhourei have the following characteristics that are generally known as distinctive features from its congeners: the area II-1 on proboscis possesses unidentate papillae bearing broad base; the area IV on proboscis bears the papillae of duct's foot-shaped with rounded teeth; the area V on proboscis has straightly conical papillae bearing slightly bifid tip; 4-16 micrognaths are arranged on the dorsal side; all parapodia have one neuropodial presetal lobe; uniramous parapodia are present on 19-26 anterior segments. As a result of the present study, the genus Glycinde is newly reported from Korean waters.

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.

Aarabellid polychaete, Drilonereis filum(Claparede, 1868), was newly recorded in Korean fauna. The specimens were collected in the mud bottom by a dredge in the west coast of Korea. The species was described with figures, and the key to genera was revised. Adding this Drilonereis filum, a total of 2 species representing 2 genera are known to Korean arabellid polychaetes.

A cossurid polychaete, Cossura brunnea Fauchald, 1972, was newly recorded in Korean fauna. Family Cossuridae is firstly known to in Korean coastal waters. The specimens of the species were collected in the muddy sand bottom. The species was described and illustrated. The key to family was provided.

A capitellid species, Heteromastus filiformis ($Clapar\grave{e}de$, 1864) is newly reported from Korean waters with the description and illustrations. Korean materials of the present study show several characteristics generally agreed well with the previous descriptions of H. filiformis as follows: the thorax is composed of the first achaetigerous peristomium and following 11 thoracic chaetigers; the capillary chaetae are present on the thoracic chaetigers 1-5 and narrowly bilimbate; the thoracic hooded hooks are appeared on the chaetigers 6-11 and have indistinct nodes on the shaft and several teeth above the main fang; the abdominal hooded hooks possess distinct nodes on the shaft and a few teeth above the main fang; the branchiae appearing on the posterior abdominal segments are the broadly-based and rounded lamellae projecting posteriorly. The authors reviewed the taxonomy of Heteromastus with a comparison of morphological characteristics among worldwide species, and provided a key of them.

A polynoid polychaete, Iphione muricata (Savigny, 1818), is newly recorded in Korean fauna. Genus Iphione was found for the first time in Korean waters. The specimen was collected in the Phyllospadix japonica bed by SCUBA diving. The species is described with figures and the key to subfamily was revised, Including this Iphione muricata, a total of 24 species representing 14 genera are known to the Korean polynoid polychaetes.

A nereid worm , Perineresi aibuhitensis has been frequently mis-identified in Korea as P.vancaurica tetradentata or Neanthes virens due to the wide variation in the number and arrangement of paragnaths on its proboscis. In this paper we re-examined ca. 50 worms collected in three intertidal mud flats of the western coast of Korea, and identified them to be P.aibuhitensis , a new record in Korea. We also described the hteronereid of this species and its biogeographical range.

Two new records of spionid polychaetes, Malacoceros reductus Blake & Kudenov, 1978 and Pseudopolydora cf. kempi (Southern, 1921), collected from Korean waters are reported here with detailed descriptions and illustrations. Malacoceros reductus, only reported in New South Wales, Australia, is distinguishable from its relatives by a prostomium with lateral horns, reduction of chaetiger 1, and the presence of the tridentate hooded hooks. Pseudopolydora cf. kempi, which has been known to have a wide geographical distribution, is characterized by a prostomium incised anteriorly, the presence of the occipital antenna, and two rows of black spots on the dorsal side. In this paper, photographs of scanning electron microscopy for characteristic features of each species are presented.
