Two new species of capitellid polychaetes are described from Hokkaido, northern Japan. Heteromastus tohbaiensis sp. nov. is very similar to H. filiformis (Claparède, 1864) and H. similis Southern, 1921, but differs from these species in having eye spots in mature specimens, distinct nodes on the thoracic hooded hooks, and by its small size. Barantolla orientalis sp. nov. is distinguished from its congeners in having the combination of an areolated thoracic epithelium, capillary setae on both rami in setigers 1-6, a caudal cirrus on the pygidium, and in the absence of branchiae on the abdominal segments.
