Abstract

During a biomonitoring assignment in the Swiss canton Ticino, an unknown Fragilaria taxon was discovered that could not be identified using the currently available literature. The results of a morphological comparison with the type material of F. recapitellata, based on light and scanning electron microscopy, showed that the new Swiss taxon has sufficient differences to be separated as a new species: Fragilaria subrecapitellata sp. nov. The new species can be separated by its lanceolate to elliptic-lanceolate valve outline with convex valve margins, and its smaller valves compared to F. recapitellata. The distribution and iconography of F. recapitellata in literature data is analysed. As a result of this analysis, Fragilaria deformis is appointed as the correct name for the taxon generally known as F. candidagilae or F. capucina var. capitellata (Grunow) Lange-Bertalot in Krammer & Lange-Bertalot.

亚头状Fragilaria subrepeatellata（Fragilariaceae，Bacillarophyta），一个来自瑞士的硅藻新种

在瑞士提契诺州的一次生物监测任务中，发现了一个未知的Fragilaria分类单元，该分类单元无法使用现有文献进行鉴定。根据光镜和扫描电子显微镜，将新的瑞士分类单元与金龟子属的模式物质进行形态学比较，结果表明，该分类单元具有足够的差异，可以作为一个新种进行分离：Fragilaria subredcapellata sp.nov，和它的较小的阀门相比，F.retaiterellata。分析了文献资料中金龟子的分布和图像学特征。根据这一分析，Fragilaria deformis被指定为分类单元的正确名称，该分类单元通常被称为F.candigilae或F.capucina var.capitellata（Grunow）Lange Bertalot in Krammer&Lange Bertolot。

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.
