ABSTRACT. Three ampharetid species, Melinantipoda quaterdentata Kucheruk, 1976, Amphicteis bifolium Kucheruk, 1976 and Amagopsis cirratus Kucheruk, 1976, are re-described based on type material. Melinantipoda quaterdentata is transferred to Melinnides Wesenberg-Lund, 1950; Amagopsis cirratus is treated as a junior synonym of Grubianella antarctica McIntosh, 1885; the generic diagnosis of Amphicteis Grube, 1850 is edited to exclude descriptions of longitudinal prostomial ridges; and Watatsumi Reuscher, Fiege et Imajima, 2015 is treated as a junior synonym of Amphicteis. A new species of Amphicteis is described, from the north-east Pacific (from the Northern Bering Sea to Honshu, at 68–256 m); the new species has one pair of foliose branchiae and well developed paleae with numerous chaetae.
