【摘要】 作者对中国科学院海洋研究所历年来在中国近海采集的笠贝总科标本进行了整理和分类学研究,共鉴定出2科5属11种,选取了其中的9种进行了齿舌解剖,利用扫描电镜对其齿舌形态进行了观察对比。结果表明,笠贝总科种类的齿舌形态包括形状、排列方式以及齿尖的大小和数目可以作为区分笠贝总科种类的分类依据之一,从而将各属、种区分开来。此外,文中利用最新的分类系统对各类群进行了整理和分类,对相关种类的分类地位进行了确立,并对各物种贝壳的主要鉴别特征进行了描述,与相似种进行了分类讨论。更多还原

【Abstract】 In this study, we investigated the morphologies of a total of 11 species of Lottioidea belonging to two families and five genera. Of these, we examined the radular features of nine species by scanning electron microscopy. The results reveal that radular morphology is a useful feature for distinguishing between Lottioidea species at the familial and generic levels, as well as the specific level. In addition, in this paper, we provide the latest classifications for all the species studied and briefly describe and compare them to related species. We also discuss the taxonomic status of some species.更多还原
