| 摘 要： | 本文描述了采自南麂列岛小柴屿岩相潮间带的一海洋底栖硅藻新种,南麂侧链藻（Pleurosira nanjiensis sp.nov.）。本研究使用光学显微镜和扫描电子显微镜对该种进行了形态学观察,并基于SSU rRNA和rbcL基因重建了其系统发育关系。南麂侧链藻具有壳面橄榄形、椭圆形或圆形,壳面隆起,单眼突出于壳表面,2–3个唇状突（rimportulae）,放射排列的线纹等特征,区别于其他侧链藻。

| Abstract: | A new marine benthic diatom, Pleurosira nanjiensis sp. nov., is described from the rocky intertidal zone of the Xiaochaiyu Island of the Nanji Islands in China. Its morphology was examined with light and scanning electron microscopy. Molecular phylogeny was reconstructed based on SSU rRNA and rbcL gene sequences. Pleurosira nanjiensis differs from congeners in possession of a combination of morphological features including the domed valve with broadly lanceolate, elliptical or circular valve outline, two elevated marginal ocelli, two (rarely three) rimportulae, and radiate striae. |
