Two newly recorded opheliid polychaetes, Armandia amakusaensis Saito, Tamaki and Imajima, 2000 and Polyophthalmus qingdaoensis Purschke, Ding and Müller, 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.
