Polychaeta is an important class of annelids and has important economic and ecological significance. The classification system of Polychaeta is being restructured and has undergone many changes. Based on previous results of cladistics analysis and volumes of Fauna Sinica, we collated keys to the orders and families of benthic groups of Polychaeta from the coastal waters of China. Referring to Rouse & Fauchald (1997) system, we sorted these benthic groups of Polychaeta into six orders, Scolecida, Spionida, Terebellida, Sabellida, Phyllodocida and Eunicida. We used existing work to compile the keys for the six orders and their constituent families. Finally, we reviewed domestic studies of coastal polychaetes and discussed the contribution of molecular studies to the development of Polychaeta phylogeny.

Key words: Polychaeta, benthos, identification key, phylogeny
