Abstract

A new monoraphid diatom, Karayevia chelonica sp. nov., is described from Nha Trang, Vietnam, isolated from marine littoral habitats. Phylogenetic analysis based on partial 18S rDNA and rbcL sequences places this species within the family Stauroneidaceae, and related to other monoraphid species. Karayevia chelonica sp. nov. differs from other species in the genus in stria density and a broad axial area on the rapheless valve. Morphology and taxonomy of the closely related genera Karayevia, Kolbesia and Madinithidium are discussed. Based on morphological characteristics, we conclude that these three genera might represent a single genus, however, further molecular investigation is required to clarify their taxonomic and systematic affinities.

文章标题单蚜虫硅藻属一新种(硅藻科:银藻科)及其分类和系统发育的评述

从越南芽庄的海洋沿岸生境中分离出一种新的广场形硅藻Karayevia chelonica sp.nov。基于部分18S rDNA和rbcL序列的系统发育分析将该物种归入Stauroneidae科，并与其他广场花类物种相关。Karayevia chelonica sp.nov.与该属其他物种的不同之处在于纹密度和无缝瓣上的宽轴向区域。对亲缘关系较近的卡拉叶菌属、科尔贝菌属和麦地菌属的形态学和分类学进行了讨论。根据形态学特征，我们得出结论，这三个属可能代表一个属，然而，还需要进一步的分子研究来阐明它们在分类学和系统上的亲缘关系。

期刊介绍： Diatom Research is the journal of the International Society for Diatom Research. The journal is published quarterly, in March, June, September and December, and welcomes manuscripts on any aspect of diatom biology. In addition to full-length papers, short notes and reviews of recent literature are published which need not contain all the sections required for full-length papers; we see these as being necessary to record information which is of interest but which cannot be followed up in detail. Discursive “Opinion” papers are encouraged which would not necessarily follow the normal lay-out. If extremely long papers are to be offered, the author(s) should contact the editors first to discuss any problems. Book reviews, obituaries and meeting reports can be published. All papers will be subject to critical review by the editors and referees, as appropriate to their content. Papers will be accepted in English only.
