| 2020年至2023年, 作者在我国黄海沿岸潮间带进行软体动物多样性调查时获取到多个耳螺科标本, 通过整理鉴定为3属3种, 分别为: 中国耳螺Ellobium chinense (Pfeiffer, 1855)、赛氏女教士螺 Pythia cecillii (R. A. Philippi, 1847) 和教徒肋耳螺Laemodonta exaratoides Kawabe, 1992。其中, 教徒肋耳螺在我国沿海系首次报道, 为中国新记录种, 作者基于COI、16S rRNA和H3基因对其进行了系统发育分析, 确定了该种在耳螺科中的分类地位。耳螺科是典型的暖水性类群, 在我国主要见于热带和亚热带海域, 之前仅有中国耳螺在浙江沿海有分布。作者认为, 耳螺科分布范围在中国海的北扩可能与全球变暖导致的黄海水温逐年升高有关。 |

| Abstract: |
| During investigations of the intertidal zone of the Yellow Sea (2020–2023), three species belonging to family Ellobiidae were sampled, including Ellobium chinense (Pfeiffer, 1855) and Pythia cecillii (R. A. Philippi, 1847) from Lianyungang (Jiangsu Province) and Laemodonta exaratoides Kawabe, 1992 from Qingdao (Shandong Province)) and Dalian (Liaoning Province). Laemodonta exaratoides Kawabe, 1992 is new to Chinese waters. Systematic position of Laemodonta exaratoides Kawabe, 1992 was clarified by reconstructed Bayesian phylogenetic tree based on two mitochondrial (COI, 16S rRNA) and nuclear (H3) genes. Ellobiidae is a group that are mainly distributed in the tropical and subtropical seas. In China, only one species, i.e. Ellobium chinense, can spread northward to the southern Yellow Sea. It is believed that the increasing number of ellobiid species found in the Yellow Sea is related to the warming climate. |
