The flora of diatoms from Brazil has been studied by several authors from the beginning of the 19(th) up to now. Some of the old lists and descriptions are unknown or have been ignored by Brazilian researchers and the situation of the names cited was not assessed. Here we compiled a list of 101 taxa of diatoms from Brazil registered by Christian Gottfried Ehrenberg during the 19(th) century. We checked the current nomenclatural status of those taxa and lectotypified species from Brazil described by this author. For this, we accessed the Ehrenberg collection in the Museum für Naturkunde, Berlin, Germany, where 11 samples from Brazil studied by Ehrenberg are housed and published in different papers. Using these samples, we found 101 taxa (specific and infraspecific) published by Ehrenberg from Brazil. Five species (Eunotia bidens Ehrenb., Eunotia depressa Ehrenb., Eunotia elephas Ehrenb., Pinnularia microstauron Ehrenb., and Terpsinoe brasiliensis Ehrenb.) were new descriptions and were lectotypified here. The other species cited for Brazil were described initially from other places. However, 23 names were invalid and one illegitimate.
从19世纪初至今，已有多位作者对巴西的硅藻植物区系进行了研究。巴西研究人员对一些早期的名录和描述并不了解或予以忽视，且未对所引用名称的情况进行评估。在此，我们汇编了一份19世纪由克里斯蒂安·戈特弗里德·埃伦贝格记录的巴西硅藻101个分类单元的名录。我们核查了这些分类单元当前的命名状况，并选定了该作者所描述的巴西物种的选定模式标本。为此，我们查阅了德国柏林自然博物馆的埃伦贝格藏品，其中保存有埃伦贝格研究过的来自巴西的11份样本，并在不同论文中发表。利用这些样本，我们发现埃伦贝格发表的来自巴西的分类单元有101个（包括种和种下分类单元）。五个物种（双齿短缝藻Eunotia bidens Ehrenb.、扁形短缝藻Eunotia depressa Ehrenb.、象形短缝藻Eunotia elephas Ehrenb.、微小等片藻Pinnularia microstauron Ehrenb.和巴西特普藻Terpsinoe brasiliensis Ehrenb.）为新描述物种，并在此选定了模式标本。其他被提及的巴西物种最初是在其他地方被描述的。然而，有23个名称无效，1个不合法。
