Abstract

The abundance and variety of benthic diatoms inhabiting tidal flats is widely acknowledged, although it has received relatively less attention than other research areas. In this investigation, we provide a formal description of a benthic diatom found in the tidal mudflat of South Korea, based on morphological and molecular characteristics and the similarities and differences between Halamphorahampyeongensis sp. nov., with morphologically similar Halamphora species are also discussed. Morphological characteristics are described from light and electron microscopy images. H.hampyeongensis is distinguished by its wide ventral sides of the valve, small and rounded areolae present across the whole valve face, and dense dorsal striae biseriate (34-38 in 10 μm). Phylogenetic analysis based on 18S rDNA and rbcL sequence data revealed that H.hampyeongensis is related to H.montana, H.mosensis, and H.specensa. The results (morphometric and molecular) provide sufficient elements to support and propose this taxon as a new species.

Halamphorahampyeongensis sp.

栖息在滩涂中的底栖硅藻数量丰富、种类繁多，这一点已得到广泛认可，但与其他研究领域相比，底栖硅藻受到的关注相对较少。在本研究中，我们根据形态学和分子特征，对韩国潮汐泥滩中发现的一种底栖硅藻进行了正式描述，并讨论了 Halamphorahampyeongensis sp.光镜和电子显微镜图像描述了其形态特征。H.hampyeongensis 的特征是：气门腹面宽大，整个气门面上都有小而圆的窠，背面有密集的双列条纹（10 μm 内有 34-38 条）。基于 18S rDNA 和 rbcL 序列数据的系统进化分析表明，咸平藻与 H.montana、H.mosensis 和 H.specensa 有亲缘关系。这些结果（形态学和分子学）为支持并提出该分类群为一个新物种提供了足够的要素。

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.
