The genus Neanthes is characterised by having conical paragnaths on both maxillary and oral rings of the pharynx and notochaetae all homogomph spinigers. Specimens of Neanthes species collected from various ecological surveys on coastal and offshore waters of Taiwan and coasts of the Kinmen Island during the past 20+ years are examined in the present study. As the result, seven new species are described, one new species record and one undetermined species are also present: N. babuzai n. sp., N. donggungensis n. sp., N. jihueiensis n. sp., N. kaomeiensis n. sp., N. kinmenensis n. sp., N. sanguensis n. sp., N. shigungensis n. sp., N. cf. nanhaiensis Wu, Sun Yang, 1981 and N. sp. 1. Key characters of these species are tabulated. A key to Neanthes species reported from Taiwanese waters is also provided.
