Abstract

During a French biomonitoring survey of the lakes in the region Rhône-Méditerranée-Corse, a large, unknown Gomphonema taxon was observed in a lake in the vicinity of the City of Lyon (Département du Rhône, France), that could not be identified using the currently available literature. Detailed light and scanning electron microscopy investigations revealed the presence of two types of valves, one bearing a thick marginal crest and valves lacking the crest. Following comparison with similar, mostly tropical Gomphonema species, the unknown taxon is described as new: Gomphonemavancampianum sp. nov. Discriminating features of the new species include the peculiar valve shape resembling a Chinese spoon, the broad upper valve part with acuminate tip, the presence of shallow depressions in the axial area, distinctly punctate striae and the occasional presence of the marginal crest. The new species was observed in several samples collected in an oligo- to mesotrophic, calcium-carbonate rich lake with a high ecological quality.

Gomphonemavancampianum sp.

在法国对罗纳-地中海-科尔斯地区的湖泊进行生物监测调查期间，在里昂市（法国罗纳省）附近的一个湖泊中观察到了一种未知的大型 Gomphonema 类群，根据现有文献无法确定该类群。详细的光镜和扫描电子显微镜研究发现了两种类型的瓣膜，一种带有厚厚的边缘嵴，另一种则没有嵴。经与类似的、主要是热带的 Gomphonema 物种比较，未知类群被描述为新种：Gomphonemavancampianum sp.该新种的特征包括：类似中国勺子的奇特瓣膜形状、瓣膜上部宽阔且顶端渐尖、轴区存在浅凹陷、明显的点状条纹以及偶尔出现的边缘嵴。在一个生态质量较高、富含碳酸钙的寡养至中养湖泊中采集的多个样本中观察到了这一新品种。

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.
