Abstract

Abstract A new monotypic diatoms genus from Brazil is described based on gatherings and descriptions from the Amazon made by Hustedt in the early 50's. Burliganiella gen. nov. is described using light and scanning electron microscope and has as generitype Burliganiella siolii (Hustedt) comb. nov., originally described within Fragilaria Lyngb. The main diagnosed features include valves slightly asymmetrical to the apical axis with a sternum located near the ventral margin (Eunotia-like) while internally having slits that are not associated with a helictoglossa and no rimoportula (which is completely absent). While some characters link the species to the ‘araphid’ genus Fragilariforma D.M. Williams & Round, Burliganiella has more shared characters with the Eunotiales. For instance, the lack of a raphe in other species of eunotioid diatoms, suggests multiple lineages within the Eunotiales have reduced or lost raphe systems, such as in the case of Burliganiella.

burliganella gen. 11 .(硅藻门，硅藻门):基于Fragilaria siolii Hustedt类型材料的中缝还原的另一个案例

摘要根据Hustedt于50年代初在亚马逊河流域的采集和描述，描述了一个新的单型硅藻属。利用光镜和扫描电镜对burliganella gen. 11进行了描述，其属型为burliganella siolii (Hustedt) comb。11 .，原属Fragilaria Lyngb。诊断的主要特征包括瓣与尖轴略微不对称，胸骨位于腹缘附近(类似于椎体)，而内部有狭缝，与螺旋舌骨无关，没有窗状孔(完全没有)。虽然一些特征将该物种与“蚜虫”属Fragilariforma D.M. Williams & Round联系起来，但Burliganiella与Eunotiales有更多的共同特征。例如，在其他种类的类针叶硅藻中缺少针叶，这表明针叶硅藻中的多个谱系已经减少或失去了针叶系统，例如伯利根菌的情况。

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.
