Abstract

Abstract Using molecular-assisted alpha taxonomy, we have uncovered two new pseudocryptic species of Champia in Bermuda, as well as have demonstrated that the European C. parvula, a name previously applied to historical Bermuda collections, and C. farlowii recently described from southern New England, USA, are not part of the island flora. We present COI-5P and rbcL, as well as morphological, evidence to describe two endemic species for the islands, C. hasselbringii sp. nov. and C. insularis sp. nov. They are similar species with compressed but variable axes and a wealth of overlapping anatomical characteristics. However, the two species are distinguished not only by their genetics, but also by reproductive features that are commonly found in the small prostrate, epiphytic species. It is possible that C. hasselbringii could be the correct name for species reported in warm waters of the western Atlantic as C. compressa or C. vieillardii, species with type localities in South Africa and New Caledonia, respectively.

关于百慕大群岛海藻的注释。标题洋贝壳科洋贝壳属二新种:洋贝壳和洋贝壳

摘要利用分子辅助α分类学，我们在百慕大发现了两个新的假隐种，并证明了欧洲的C. parvula(以前用于百慕大历史标本的名称)和最近在美国新英格兰南部描述的C. farlowii不是岛屿植物群的一部分。我们提出了COI-5P和rbcL，以及形态学证据来描述岛上的两个特有物种，C. hasselbringii sp. 11和C. insularis sp. 11 .它们是相似的物种，具有压缩但可变的轴和丰富的重叠解剖特征。然而，这两个物种的区别不仅在于它们的遗传，还在于生殖特征，这些特征在小型匍匐附生物种中很常见。C. hasselbringii可能是在西大西洋温暖水域报告的C. compressa或C. vieillardii物种的正确名称，这些物种的模式地点分别在南非和新喀里多尼亚。

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.
