Abstract

During the study of freshwater diatom communities in Hainan Province, China, we uncovered an unknown diatom species of the genus Decussiphycus, which is described as Decussiphycussinensis sp. nov. herein. The description is based on LM and SEM investigations; morphologically, the new species is compared to other taxa belonging to the genus. We complemented the description with the results of a molecular analysis based on SSU rDNA and rbcL sequencing. Molecular data is acquired for Decussiphycus for the first time. Hereby, we discuss the phylogenetic relationships between this genus and its closest allies - Aneumastus and Mastogloia, demonstrating the affinity of Decussiphycus within the order Mastogloiales.

在对中国海南省淡水硅藻群落的研究过程中，我们发现了一个未知的硅藻属物种，本文将其描述为Decussiphycussinensis sp.nov.。该描述基于 LM 和 SEM 研究；在形态学上，该新种与属于该属的其他类群进行了比较。我们利用基于 SSU rDNA 和 rbcL 测序的分子分析结果对该描述进行了补充。这是首次获得 Decussiphycus 的分子数据。在此，我们讨论了该属与其最亲近的盟友--Aneumastus 和 Mastogloia 之间的系统发育关系，证明了 Decussiphycus 在 Mastogloiales 目中的亲缘关系。
