Abstract

Members of the genus Pseudopterogorgia Kükenthal, 1919 are widely distributed in shallow water of the Indo-West Pacific. During an investigation of benthic biodiversity in the subtidal zone surrounding the Nanji Islands in the East China Sea, two specimens of Pseudopterogorgia were collected and described as a new species based on an integrated morphological-molecular approach. Pseudopterogorgiananjiensis sp. nov. is most similar to P.fredericki Williams & Vennam, 2001 in the irregular branching form and indistinct scaphoids, but differs by the coenenchymal sclerite content of distinct capstans and a few warty spindles and radiates (vs. mostly warty spindles and a few capstans), and a purplish colony (vs. white, pink to deep rose). Molecular phylogenetic analyses, based on the mtMutS-COI gene sequences, delineated a monophyletic clade encompassing all assessed Pseudopterogorgia species. Within this clade, P.nanjiensis sp. nov. showed a close phylogenetic affinity with both P.fredericki and P.australiensis Ridley, 1884.

A new gorgonian Pseudopterogorgiananjiensis sp.

Pseudopterogorgia Kükenthal, 1919 属的成员广泛分布于印度-西太平洋的浅水区。在对中国东海南麂列岛周围潮下带底栖生物多样性的调查中，采集到了两件伪opterogorgia 标本，并根据形态-分子综合方法将其描述为一个新物种。Pseudopterogorgiananjiensis sp. nov.与 P.fredericki Williams & Vennam, 2001 最为相似，都具有不规则的分枝形态和不明显的鞘状突起，但不同之处在于同源硬骨中含有明显的鞘状突起和少量疣状轴及放射状突起（与之相比，大部分为疣状轴和少量鞘状突起），以及略带紫色的菌落（与之相比，菌落呈白色、粉红色至深玫瑰色）。基于 mtMutS-COI 基因序列的分子系统进化分析划定了一个单系支系，包括所有已评估的 Pseudopterogorgia 物种。在该支系中，P.nanjiensis sp.nov.与 P.fredericki 和 P.australiensis Ridley, 1884 在系统发育上亲缘关系密切。

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.
