Abstract In this paper, the material of the genus Ampharete Malmgren, 1866 from China Seas (Annelida: Ampharetidae) deposited in the collections of the Marine Biological Museum of the Chinese Academy of Sciences (MBMCAS) is reviewed and previous identifications reassessed. In total, four species were found among all specimens examined. Material previously attributed to A. acutifrons (Grube, 1860) and A. arctica Malmgren, 1866 had been misidentified and is now confirmed as belonging to A. lindstroemi Hessle, 1917 and A. finmarchica (Sars, 1865), respectively; the presence of A. falcata Eliason, 1955 is also confirmed; A. orientalis (Annenkova, 1929) is recorded for the first time from China.

1 INTRODUCTION Ampharetids are tubicolous, infaunal species in muds and sands at all water depths, most of the adults are 1–6 cm long (Jumars et al., 2015). Ampharetidae Malmgren, 1866 comprises approximately 230 species distributed among 63 genera, 33 of them monotypic (Read and Fauchald, 2020). Ampharete Malmgren, 1866 is the most speciose genus in the family Ampharetidae. We agree with Imajima et al. (2012) that the genus Asabellides Annenkova, 1929, Parampharete Hartman, 1978, Pterampharete Augener, 1918 and Sabellides Milne-Edwards in Lamarck, 1838 are the junior synonyms of Ampharete. Consequently, Ampharete would include ampharetids with papillose buccal tentacles, prostomium without glandular ridges, with the middle lobe delimited by a more or less U-shaped incision, four or exceptionally three pairs of branchiae and 11 or 12 thoracic uncinigers. Three Ampharete species were reported from the coasts of China according to the checklist of Huang (1994) and Liu (2008). They are A. acutifrons (Grube, 1860), A. arctica Malmgren, 1866 and A. reducta
Chamberlin, 1920. Afterwards, Sui (2013) firstly reported another three species from China, A. finmarchica (Sars, 1865), A. lindstroemi Hessle, 1917 and A. falcata Eliason, 1955. We have checked the Ampharete material deposited in MBMCAS, reassessed previous identifications and confirmed the presence of four species in China Seas: Ampharete finmarchica (Sars, 1865), A. lindstroemi Hessle, 1917, A. orientalis (Annenkova, 1929) and A. falcata Eliason, 1955; A. reducta Chamberlin, 1920 is an invalid record in China because it was
