Abstract

During a biodiversity survey around the historic Flemish town of Damme, a large Fragilariforma taxon was observed in a small pond that could not be identified using the currently available literature. Detailed light and scanning electron microscopy investigations revealed the presence of so-called resting spores within the frustules. Following comparison with similar linear, long-celled Fragilariforma species, the unknown taxon is described as new: Fragilariformameireana sp. nov. Discriminating features of the new species include the long, linear valves with protracted, distinctly rostrate apices, the absence of ribbon-like colonies, the presence of a rimoportula on both apices and the formation of internal resting spores.

Fragilariformameireana,一种产于佛兰德斯产生内瓣的麒麟硅藻新种(硅藻门)。
在历史悠久的佛兰德小镇Damme周围进行的生物多样性调查中,在一个小池塘中观察到一个大型Fragilariforma分类群,该分类群无法使用现有文献进行识别。详细的光镜和扫描电子显微镜调查显示,所谓的休眠孢子存在于小菌落内。与相似的线形长细胞Fragilariformameireana sp. nov进行比较后,这个未知的分类群被描述为新物种:Fragilariformameireana sp. nov.新物种的特征包括长而线形的阀瓣,顶端延长,明显的顶状,没有缎带状的菌落,两个顶端都有一个窗孔,以及内部静止孢子的形成。
