During a floristic survey of temporal ponds in the Sahelian area of North Senegal, a new Craticula species (Bacillariophyceae) was discovered, and it is named here Craticula widouensis Beauger, C.E.Wetzel & Ector sp. nov. The new taxon is formally described using light and scanning electron microscopy. The species presents a unique set of morphological characteristics, including valve dimensions, outline, and presence of conspicuous elongated silica slats at the valve face/valve mantle junction and some narrow apically elongated struts irregularly distributed on the valve face, which make Craticula citrus (Krasske) E. Reichardt the most similar taxon to our knowledge. The ecological preferences of Craticula widouensis sp. nov. are eutrophic, contaminated, and hot ponds. A morphological comparison with the most similar species and a checklist of Craticula taxa are also presented.

在对塞内加尔北部萨赫勒地区临时池塘进行的植物学调查中，发现了一种新的Craticula物种（Bacillariophyceae），在此命名为Craticula widouensis Beauger，CEWetzel和Ector sp。年11月。使用光学和扫描电子显微镜正式描述了新的分类单元。该物种具有独特的形态学特征，包括瓣膜尺寸，轮廓以及在瓣膜面/瓣膜地幔交界处存在明显的细长二氧化硅板条，在瓣膜面上不规则地分布着一些细小的顶端细长的支柱，这使得桔梗变成了柑桔（Krasske ）E. Reichardt是我们所知的最相似的分类单元。景天草的生态偏好sp。十一月 富营养化，污染和热水池。还介绍了与最相似物种的形态比较和Craticula类群的清单。
