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 , with morphologically similar species are also discussed. Morphological characteristics are described from light and electron microscopy images. 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 L sequence data revealed that is related to , , and . The results (morphometric and molecular) provide sufficient elements to support and propose this taxon as a new species.
尽管潮间带底栖硅藻的丰富度和多样性相较于其他研究领域受到的关注相对较少，但它们的存在已得到广泛认可。在本研究中，我们基于形态学和分子特征以及与形态相似物种之间的异同，对在韩国潮间带泥滩发现的一种底栖硅藻进行了正式描述，并讨论了形态相似的物种。形态特征是根据光学显微镜和电子显微镜图像描述的。该物种的特征在于其瓣膜腹侧宽阔，整个瓣膜表面分布着小而圆的网纹，以及密集的双列背纹（每10μm有34 - 38条）。基于18S rDNA和L序列数据的系统发育分析表明，该物种与[具体物种1]、[具体物种2]和[具体物种3]相关。这些结果（形态测量和分子方面）提供了足够的依据来支持并提议将这个分类单元认定为一个新物种。
