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.
果胶蛸科 Quatrefages, 1865 广泛分布，其半圆形的具有两列粗壮的金色薄片的鳃盖和由沙子或贝壳碎片制成的冰淇淋锥形管，使其与其他多毛类动物明显区分开来。共检查了来自中国沿海水域的 387 个果胶蛸标本。鉴定并描述了属于三个果胶蛸属的 11 种，包括 4 个新种（Amphictene jianqingi n. sp.、Pectinaria lizhei n. sp.、Pectinaria dayaensis n. sp.、Pectinaria xiukaii n. sp.）和一个新记录种（Pectinaria plurihamus Choi, Jung Yoon, 2017）。给出了中国海域果胶蛸属和记录种的属的关键。基于五个基因（COI、16S rDNA、18S rDNA、28S rDNA 和 H3）的部分序列，分析了果胶蛸的系统发育关系。带有分子数据的三个新种 Amphictene jianqingi n. sp.、Pectinaria lizhei n. sp. 和 Pectinaria dayaensis n. sp. 得到了很好的支持。三种 Lagis 种（L. koreni、L. bocki 和 L. plurihamus）、五种 Pectinaria 种（P. dayaensis、P. dodeka、P. gouldii、P. lizhei 和 P. torquata）和三种 Amphictene 种（A. auricoma、A. alata 和 A. jianqingi）没有形成一个支持度很好的分支，这需要更详细的分析。
