摘　　要：本文对栖息在我国淡水鱼苗培育池及水稻田中的6种原蚌虫(隶属于甲壳门,鳃足纲,介甲目,蚌壳虫科)进行了分类记述。其中的兖州原蚌虫Eocyzicus yanzhouensis sp.nov.及拟莱阳原蚌虫E.paralaiyangensis sp.nov.系2新种。分别列表比较了新种与其近似种佩里原蚌虫E.perrieri Daday,1914,多刺原蚌虫E.spinfer Durga Prasad et al,1981及莱阳原蚌虫E.laiyangensis Hu,1985的主要形态区别特征。文中附有6种原蚌虫的检索表及形态特征图54幅。本文记述种的名录如次: 1.东方原蚌虫Eocyzicus orientalis Daday,1914; 2.蒙古原蚌虫E.mongolianus Ueno,1927; 3.戴维原蚌虫E.davidi(Simon,1886)Brtek et al,1984; 4.莱阳原蚌虫E.laiyangensis Hu,1985; 5.兖州原蚌虫,(新种)E.yanzhouensis sp.nov.; 6.拟莱阳原蚌虫,(新种)E.paralaiyangensis sp.nov.The taxonomic characters of six species of the genus Eocyzicus Daday, 1913(Crustacea: Branchiopoda, Conchostraca, Cyzicidae) distributed in fresh - water fish - fry rearing ponds or paddy fields over China, viz. , 1. Eocyzicus orientalis Daday, 1914, 2. E. mongolianus Ueno, 1927, 3. E. davidi (Simon, 1886), Brtek et al, 1984, 4. E. luiyangensis Hu, 1985, 5. E. yanzhouensis sp. nov. and 6. E. paralaiyangensis sp. nov. , are described in this paper. Two tables are given to compare the main morphological characteristics of the two new species with those of similar species, E. perrieri Daday, 1914, E. spinifer Durga et al, 1981 and E. laiyangensis Hu, 1985. A key provides the guidance for distinguishing the six species. Fifty-four figures of them are furnished in illustration.
