N1 - Funding Information:
A total of 387 specimens of pectinariids from the coastal waters of China could be identified to genus and species. They were collected during benthic ecology surveys conducted during the implementation of the following projects: Comprehensive Investigation and Evaluation of Coastal Waters of China from 2006–2007 (The 908 Program); Investigation and Evaluation of Marine Ecology of Chang Island, Shandong Province in August and November 2018; Investigation Cruise of Natural Science Foundation to the northern Yellow Sea in September and December 2017; Intertidal Investigation of the First Beach of Qingdao, Shandong Province in June 2020; Intertidal Investigation of Eyu Island in Xiamen, Fujian Province in May 2018 and 2019; Monitoring Program of the Ecological Status of the northern South China Sea; Macrobenthic Investigation of Daya Bay, Guangdong Province in four seasons of May 2015–January 2016. All these specimens are deposited in the following institutions: South China Sea Environmental Monitoring Center, State Oceanic Administration, Guangzhou, China (SCSEMC); Third Institute of Oceanography, Ministry of Natural Resources, Xiamen, China (TIO); Marine Biological Science Museum of the Chinese Academy of Sciences, Qingdao, China (MBM); South China Sea Marine Biology Collections, Chinese Academy of Sciences, Guangzhou, China (SCSMBC).

N2 - Pectinariidae Quatrefages, 1865 is widely distributed, and easily distinguished from other polychaetes by their characteristic semi-circular operculum with two rows of stout golden paleae and “ice-cream cone”-shaped tubes made of sand or shell fragments. A total of 387 specimens of pectinariids from the coastal waters of China were examined. Eleven species belonging to three genera of pectinariids were identified and described, including four new species (Amphictene jianqingi n. sp., Pectinaria lizhei n. sp., Pectinaria dayaensis n. sp., Pectinaria xiukaii n. sp.) and one new record (Pectinaria plurihamus Choi, Jung & Yoon, 2017). A key to genera of Pectinariidae and recorded species from Chinese waters is given. Based on partial sequences of five genes (COI, 16S rDNA, 18S rDNA, 28S rDNA and H3), the phylogenetic relationship of pectinariids is analyzed. The three new species Amphictene jianqingi n. sp., Pectinaria lizhei n. sp. and Pectinaria dayaensis n. sp. with molecular data are well supported. Three species of Lagis (L. koreni, L. bocki and L. plurihamus), five species of Pectinaria (P. dayaensis, P. dodeka, P. gouldii, P. lizhei and P. torquata), and three species of Amphictene (A. auricoma, A. alata and A. jianqingi) do not form a well supported clade, which requires more detailed analyses.
