| 摘要: |
| 在对历年来在中国近海采集的滨螺科（Littorinidae）贝类标本进行系统整理和研究的过程中，鉴定出隶属于豆滨螺属Peasiella的2个物种：波部豆滨螺Peasiella habei D.Reid&Mak，1998和罗豆滨螺Peasiella roepstorffiana Nevill，1885。标本采自中国山东省及海南省沿海区域，栖息于潮间带及浅海的礁石上。本文对2个物种的贝壳形态、齿舌特征及地理分布等方面进行了详细描述，并对其分类地位以及主要鉴别特征进行了讨论，提出齿舌数量及排列方式即齿式为该属物种区分的重要依据。同时，将张氏马蹄螺Trochus zhangi Dong，2002归于罗豆滨螺Peasiella roepstorffiana Nevill，1885的次异名。 |

| Abstract: |
| Two species belonging to the genus Peasiella were identified during the systematic study of the shellfish specimens of Family Littorinidae collected in the coastal waters of China over the years:Peasiella habei D. Reid & Mak, 1998 and Peasiella roepstorffiana Nevill, 1885. The specimens were collected from the coast of Shandong and Hainan Provinces, China, and inhabited on coastal intertidal zones and shallow reefs. In this paper, the shell morphology, radula characteristics, and geographical distribution of the two species are described in detail, and their taxonomic status and main identification characteristics are discussed. It shows that the number and arrangement of radulae are important taxonomic features in diagnosing species of Peasiella. In addition, Trochus zhangi Dong, 2002 was attributed to the junior synonym of Peasiella roepstorffiana Nevill, 1885. |
