Abstract

Regions with high levels of biodiversity, which mostly correspond to tropical regions, can be treated as treasuries of endemism, even for single-celled life forms. Learning about these areas, and the species present in them, is key to understanding the processes that govern their emergence and sustainability. This paper is a contribution towards revealing the biodiversity of marine benthic diatom species of the world. The samples used in this paper were taken from East Java (Indonesia), Nosy Be (north-west Madagascar) and the Tagus River estuary (Portugal). We describe a new diatom genus, Catenulopsis, and propose the first species of the genus from Nosy Be, named Catenulopsis catenulafalsa. We also describe two new Catenula species, one from Java (Catenula javanica) and the other from Portugal (Catenula brotasiae). The paper also discusses the characteristics of Catenula adhaerens and variations in the species across geographic space. We characterize the morphological variation of C. adhaerens in samples from equatorial West Africa, South Africa, Portugal, Japan, Madagascar and Indonesia.

热带和温带海洋沿岸栖息地的新硅藻（Bacillarophyta），包括Catenuropsis gen.nov.和两个Catenula物种的描述

生物多样性水平高的地区，大多对应于热带地区，可以被视为地方病的宝库，即使是单细胞生命形式也是如此。了解这些区域以及其中存在的物种，是理解其出现和可持续性的过程的关键。本文为揭示世界海底硅藻物种的生物多样性做出了贡献。本文中使用的样本取自东爪哇（印度尼西亚）、诺西贝（马达加斯加西北部）和塔霍河河口（葡萄牙）。我们描述了一个新的硅藻属Catenulopsis，并从Nosy-Be中提出了该属的第一个物种，命名为Catenulopis catenulafalsa。我们还描述了两个新的Catenula物种，一个来自爪哇（Catenula javanica），另一个来自葡萄牙（Catenulla brotasiae）。文中还讨论了附着Catenula adhaerens的特征和物种在地理空间上的变化。我们对来自赤道西非、南非、葡萄牙、日本、马达加斯加和印度尼西亚的C.adhaerens的形态变化进行了表征。

期刊介绍： Diatom Research is the journal of the International Society for Diatom Research. The journal is published quarterly, in March, June, September and December, and welcomes manuscripts on any aspect of diatom biology. In addition to full-length papers, short notes and reviews of recent literature are published which need not contain all the sections required for full-length papers; we see these as being necessary to record information which is of interest but which cannot be followed up in detail. Discursive “Opinion” papers are encouraged which would not necessarily follow the normal lay-out. If extremely long papers are to be offered, the author(s) should contact the editors first to discuss any problems. Book reviews, obituaries and meeting reports can be published. All papers will be subject to critical review by the editors and referees, as appropriate to their content. Papers will be accepted in English only.
