摘要

在最近对喀麦隆地下水动物群的调查中，在杜阿拉市的水井中采集了一种新的甲藻属Metastenasellus，M.boutini sp.nov.的标本。这个新物种可以很容易地与该属的其他物种区分开来，因为它的体积相对较大（高达11毫米），长约1和2倍于长约7的倍，雄性中长约2的形状（原足类动物上有一个外叶，精管的远端稍微突出第二个，外足类动物缺乏远端刚毛），和欧洲的一半长度的平民。提供了Metastenasellus物种的生态学数据和关键。我们还对非洲Stenasellidae的文献进行了详尽的分析，以研究该科在非洲大陆的地理分布，并讨论了关于非洲物种起源的一些假设。

Distribution of Stenasellidae in Africa and description of a new species of Metastenasellus from Cameroonian groundwaters

During recent investigations of the groundwater fauna of Cameroon, specimens of a new species of the stygobitic genus Metastenasellus, M. boutini sp. nov. were collected in wells of the city of Douala. The new species can be easily distinguished from the other species of the genus by its relatively large size (up to 11 mm), pleonite 1 and 2 half the length of pereonite 7, the shape of pleopod 2 in males (presence of an external lobe on the protopodite, distal part of the spermatic duct slightly protruding out of the second article, lack of a distal seta on the exopodite), and uropod half the length of the pleotelson. Ecological data and a key to Metastenasellus species are provided. We also performed an exhaustive analysis of the literature on Stenasellidae in Africa to study the geographical distribution of the family in this continent and discuss some hypotheses about the origin of African species.

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.
