摘要

研究并描述了来自中国南方青衣江和茂兰自然保护区的一个新的单瓣膜硅藻物种 Cocconeis crisscrossis You, Yu, Kociolek & Wang, sp.形态学描述基于光学显微镜和扫描电子显微镜观察，并将该新种与该属的相似类群进行了比较。Cocconeis crisscrossissp.nov.的独特特征包括其中心区域不规则地向两侧延伸，具有封闭的瓣膜，瓣膜边缘具有严重硅化的流苏状边缘，瓣膜的两极具有 "剑形 "硅质延伸。这些特征将该新物种与该属的其他物种区分开来。这一新物种发现于碱性水体中，包括溪流、瀑布和池塘。它通常作为附生植物出现在石头上，但也出现在苔藓等其他基质上。

Cocconeis crisscrossis sp. nov., a new monoraphid diatom (Bacillariophyta) from southern China

A novel monoraphid diatom species, Cocconeis crisscrossis You, Yu, Kociolek & Wang, sp. nov. is examined and described from the Qingyi River and Maolan Nature Reserve of southern China. The morphological description is based on light microscopy and scanning electron microscopy observations and the new species is compared with similar taxa in this genus. The characteristics unique to Cocconeis crisscrossissp. nov. include its central area extending irregularly to both sides, it having closed valvocopulae with heavily silicified fimbriate margins and poles of the valvocopulae have ‘sword-shaped’ siliceous extensions. These features differentiate this new species from others in the genus. This new species was found in alkaline waterbodies, including streams, waterfall and ponds. It was usually found as an epiphyte on the stones; however, it was present on other substrates such as mosses.

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.
