Abstract

Abstract The rare endemic Mediterranean alga Kallymenia spathulata was collected at Nice and Saint Raphael in June 2013 during a survey conducted along the French Mediterranean coast between Menton and Toulon (French Riviera). DNA barcode sequences (COI-5P) generated from the five collected specimens were identical and allied with Felicinia marginata, another Mediterranean endemic that is classified within the Halymeniaceae (Halymeniales) whereas the genus Kallymenia is representative of the Kallymeniaceae (Gigartinales). We further confirmed the alliance of K. spathulata with Felicinia marginata by conducting phylogenetic analyses inferred by combined genes including Cox1, rbcL and LSU. Unfortunately, none of the specimens were fertile, precluding emending the description of the reproductive anatomy of this species. In light of our phylogenies, we propose the novel combination Felicinia spathulata. The genus Felicinia now comprises two species, both endemic to the Mediterranean Sea.

地中海罕见特有种狐獴(Kallymenia spathulata)的认识:DNA系统发育表明该物种为Halymeniaceae (Halymeniales)而非Kallymeniaceae (Gigartinales)，并提出Felicinia spathulata comb。11月。

2013年6月，在法国里维埃拉的芒通和土伦之间的法国地中海沿岸，在尼斯和圣拉斐尔采集到罕见的地中海特有藻类Kallymenia spathulata。5个标本的DNA条形码序列(COI-5P)与Felicinia marginata同源，Felicinia marginata属于Halymeniaceae (Halymeniales)，而Kallymenia属是Kallymeniaceae (Gigartinales)的代表。通过对Cox1、rbcL和LSU等组合基因进行系统发育分析，进一步证实了spathulata与Felicinia marginata的亲缘关系。不幸的是，没有一个标本是可育的，这就妨碍了对该物种生殖解剖学描述的修改。根据我们的系统发育，我们提出了一种新的组合，即spathulata。Felicinia属现在包括两个物种，都是地中海特有的。

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.
