Abstract

We describe a new species of diatom, Psammodictyon taihuensis sp. nov., collected from the Taihu Basin, Jiangsu Province, China. There are several features of this diatom that suggest it should be included in the genus Psammodictyon, notably the possession of panduriform valves characterized by a longitudinal fold near the apical axis, coarsely areolate striae, and a keeled raphe system present on the valve margin. This species is distinct from others in the genus by its small size, being only 16.5-25.0 μm long and 10.0-12.5 μm wide in the central region, and with the widest valve being 10.5-13.5 μm in width. There are 8-11 distinct fibulae per 10 μm and the striae are composed of 18-22 coarse areolae per 10 μm. This is the first report of a freshwater member of the genus Psammodictyon in China, which expands the known geographical and ecological distributions of the genus and enhances our understanding of freshwater diatom diversity in China.

标题江苏太湖盆地一新种

本文报道了一种新的硅藻，太湖硅藻Psammondictyon taihuensis sp.nov.，产于中国江苏省太湖流域。这种硅藻的几个特征表明它应该被包括在Psammodictyon属中，特别是具有盘状瓣，其特征是在心尖轴附近有一个纵向褶皱，粗糙的乳晕状条纹，瓣缘上有一个龙骨状中缝系统。本种与本属其他种的不同之处在于其体型较小，中部长16.5-25.0μm，宽10.0-12.5μm，最宽的瓣宽10.5-13.5μm。每10μm有8-11个明显的腓骨，纹由18-22个粗糙的乳晕组成。这是Psammondictyon属淡水成员在中国的首次报告，扩大了该属已知的地理和生态分布，增强了我们对中国淡水硅藻多样性的了解。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
