Abstract

The genus SinonereisWu & Sun, 1979 and the species Sinonereis heteropodaWu & Sun, 1979 were described from Chinese waters, based on only epitokous specimens with modified dorsal cirri in chaetigers 5-7 and bare pharynx. In the same publication, another species based on only atokes was described, Nicon sinicaWu & Sun, 1979. We show that N. sinica is a junior synonym of S. heteropoda based on their affinities in chaetal and parapodial features. We redefine Sinonereis and formally synonymize N. sinica and S. heteropoda. Sinonereis closely resembles NiconKinberg, 1865 and KainonereisChamberlin, 1919, but Sinonereis differs from them by having napiform dorsal cirri in chaetigers 5-7, and by lacking notopodial dorsal ligules in chaetiger 3 in both atokes and epitokes.
