摘要：
Sabaco sinicus sp.nov.is described based on material collected from Chinese coast.It has been misidentified as Asychis gangeticus Fauvel,1932 since Uschakov and Wu(1962).Here,we recognized it as a new species based on combination of the following characters:dark-brown pigmentation spots on nuchal grooves and first three chaetigers;glandular pattern on chaetigers 4–6;preanal achaetigerous segments absent;anal plaque trumpetshaped with a disc-shaped dorsal lobe;notochaetae consisting of geniculate capillaries and fine capillaries with or without spinose spiral bands;neurochaetae presented as a single row of rostrate uncini.Asychis gangeticus differ from the new species in having no pigmentations on body and a triangular dorsal lobe of anal plaque.Distribution region of this species have moved northward significantly from sea area south of Changjiang Estuary since the1950s.
