Abstract

We describe three new Achnanthidium species, A. lacustre sp. nov., A. sublanceolatum sp. nov., and A. taipingensis sp. nov., from Taiping Lake, Anhui Province (China) based on light and scanning electron microscopy. A. lacustre sp. nov. belongs to the "A. minutissimum complex" of the genus, based on it having straight external distal raphe fissures and round to elliptical areolae. Both A. sublanceolatum sp. nov., and A. taipingensis sp. nov. belong to the "A. pyrenaicum complex" of the genus, based on them having transpically-elongated areolae and deflected external distal raphe fissures. All three species are sufficiently different from other similar species based on valve outline, shape of the axial and center areas, and striae density. These three new species are all observed in benthic collections from Taiping Lake.

太平湖阿胶属三新种（硅藻门，阿胶科）

基于光镜和扫描电子显微镜，我们描述了来自安徽省太平湖的三个新的Achnanthidium物种，A.lacustre sp.nov.，A.sublanceolatum sp.nov..和A.tapingsis sp.novs。A.lacustre sp.nov.属于该属的“A.minutissimum复合体”，因为它有直的外部中缝远端裂隙和圆形到椭圆形的乳晕。A.sublanceolatum sp.nov.和A.tapingsis sp.nov..都属于该属的“A.pyrenaium复合体”，因为它们具有透明细长的乳晕和偏斜的中缝远端外部裂隙。根据瓣膜轮廓、轴向和中心区域的形状以及条纹密度，这三种物种与其他类似物种有很大的不同。这三个新物种都是在太平湖的底栖生物群落中观察到的。

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.
