| 摘要: |
| 小型腹足类生物在我国种类繁多, 但其相关研究在国内基本属于空白。本文对荣成天鹅湖大叶藻间的2种小型腹足类生物进行了形态学及分子生物学(16S和28S rRNA基因片段)研究。结果表明, 根据形态学所鉴定的短剑螺属未定种Machaeroplax sp., 应为畦螺属未定种Lirularia sp.; 分子生物学研究结果支持形态学对刺绣翼螺Alaba picta的鉴定。同时, 与A. picta有一定形态学差异的其它4种相近形态的小型腹足类, 在基因序列及遗传距离上与刺绣翼螺非常接近, 亦应为刺绣翼螺Alaba picta。 |

| Abstract: |
| There is a great diversity of small gastropods in China, however, the related researches are nearly vacant. We sampled 2 species of small gastropods habitating among the Zostera marina L. from the Swan Lake, Rongcheng Bay, China and the 16S and 28S rRNA were sequenced. Based on the molecular data, sequences alignment, genetic distances and phylogenetic studies were conducted. The results showed that Machaeroplaxsp. identified according to the morphology should be Lirularia sp.; and that 4 gastropods with obvious morphological variances from Alaba picta had been classified as Alaba picta according to the molecular analysis. |
