Abstract

Abstract Epithemia hirudiniformis and three morphologically related taxa, described in Rhopalodia by O. Müller from material collected in East Africa at the end of the 19th and the beginning of the 20th century were re-evaluated and lectotypes designated. Rhopalodiella as a new subgenus is proposed which refines O. Müller's infrageneric classification and to which all these taxa belong. In addition, the type of Epithemia rhopala, described by Ehrenberg from Egypt, was studied to examine the assumed synonymy, introduced by Hustedt, with some of Müller's species. This study, using light and scanning electron microscopy, was not only based on historic material but also more recent material from Africa, including samples from the Island of Reunion from which the new species Epithemia vandevijveri is described. The distribution of Epithemia subg. Rhopalodiella, known to be restricted to tropical Africa, is discussed based on literature data and own observations. Corresponding to recent molecular-based studies, Rhopalodia is given a new status as subgenus.

水蛭癣亚属及其相关分类群。11 .与Epithemia亚群的比较。产自东非的芽孢杆菌

摘要对19世纪末20世纪初在东非收集的资料中由O. m ller在《Rhopalodia》中描述的水蛭形Epithemia hirudiniformis和3个形态相关的分类群进行了重新评价和鉴定。提出了一个新的亚属Rhopalodiella，该亚属完善了O. m ller的近属分类，并将所有这些分类群归为该亚属。此外，研究了Ehrenberg从埃及描述的Epithemia rhopala的类型，以检验Hustedt引入的假设同义词与一些m ller的物种。这项研究，使用光学和扫描电子显微镜，不仅基于历史材料，而且基于来自非洲的最新材料，包括来自留尼旺岛的样本，其中描述了新物种Epithemia vandevijveri。Epithemia亚群的分布。根据文献资料和自己的观察，讨论了已知局限于热带非洲的Rhopalodiella。根据最近的分子基础研究，Rhopalodia被赋予了一个新的亚属地位。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
