摘要
基于光学和扫描电子显微镜,我们研究并描述了来自中国云南省湿壁的硅藻最初被描述为Melosira radiato-sinuata var. yunnanica的晶体形态。硅藻瓣的中央部分有齿状突起,瓣周围的内部有明显的空洞。阀套高度变化。基于这些特征,我们将其归入直叶蝉属,认为它是一个独特的种。将它与其他类似的“中心”硅藻进行比较。其他几个类似的分类群也被正式划归到正形虫属,包括M. radiato-sinuata和Melosira波动型变种三胞虫。“Orthoseira sp. #2”的sense spulding和Kociolek被正式描述为一个新物种。讨论了形态多样性的属内的直立木提出。
New and interesting diatoms from the Shimen Wetwalls, Yunnan Province, China. I. Valve morphology of Melosira radiato-sinuata var. yunnanica Chen (Bacillariophyta: Melosirales) from Yunnan Province, China, with comments on its systematic position
We examine and describe the frustular morphology of the diatom originally described as Melosira radiato-sinuata var. yunnanica from a wet wall in Yunnan Province, China, based on light and scanning electron microscopy. This diatom has carinoportulae present in the central portion of the valve, and prominent caverns present internally around the periphery of the valves. The valve mantle height varies. Based on these features M. radiato-sinuata var. yunnanica is transferred to the genus Orthoseira and recognized as a distinct species. It is compared to other, similar ‘centric’ diatoms. Several other, similar taxa are also formally transferred to the genus Orthoseira, including M. radiato-sinuata, and Melosira undulata var. triocellata. ‘Orthoseira sp. #2' sensu Spaulding and Kociolek is formally described as a new species. A discussion of the morphological diversity within the genus Orthoseira is presented.
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.
