A new species of the ampharetid genus Amphicteis, A. hwanghaiensis sp. nov., is described based on material from the Yellow Sea. The new species is characterized by the possession of long, stout, golden paleae with blunt tips, digitiform rudimentary notopodia on the abdominal uncinigers, uncini with a subrostral process, and a narrow rectangular hump separating branchial groups. Amphicteis dalmatica was redescribed from type materials at the Australian Museum, Sydney, and the differences between A. dalmatica and A. hwanghaiensis sp. nov. are discussed. A key to distinguish Amphicteis species described or reported in Western Pacific waters is provided.
