During a survey of the Indonesian diatoms, five D.G.Mann taxa that could not be identified, based on the available literature were discovered. Based on light microscopy, scanning electron microscope observations and comparisons with similar taxa, all of them are described as new species. All taxa were found on mosses growing on tree trunks and concrete on the islands of Banda Besar and Seram and from spring on Java Island. is most similar to and , but it can easily be distinguished from both taxa, based on the lower striae density, the narrower valves and the well-developed silica ridges on the valve face/mantle junction. resembles , but they can be easily distinguished, based on their valve widths and the direction of the grooves located on the distal and proximal raphe endings. is most similar to , and . Amongst all the species compared, is the only one with a highly asymmetrical central area, with the isolated pore located on the wider side. shares similarities with and , but it has a notably higher stria density. From , it can also be separated by the morphology of striae and the lack of ghost areolae in the central area. is unique in the whole genus due to the presence of multiple isolated pores.
在对印度尼西亚硅藻的调查中，发现了5个基于现有文献无法鉴定的D.G.曼恩分类群。基于光学显微镜、扫描电子显微镜观察以及与相似分类群的比较，所有这些分类群均被描述为新物种。所有分类群均发现于班达贝萨尔岛和塞拉姆岛树干和混凝土上生长的苔藓以及爪哇岛的泉水中。[此处原文缺失物种名]与[此处原文缺失物种名]和[此处原文缺失物种名]最为相似，但基于较低的条纹密度、较窄的瓣膜以及瓣膜面/套膜交界处发育良好的硅质脊，它很容易与这两个分类群区分开来。[此处原文缺失物种名]与[此处原文缺失物种名]相似，但基于它们的瓣膜宽度以及位于远端和近端中缝末端的沟槽方向，它们很容易区分。[此处原文缺失物种名]与[此处原文缺失物种名]、[此处原文缺失物种名]和[此处原文缺失物种名]最为相似。在所有比较的物种中，[此处原文缺失物种名]是唯一具有高度不对称中心区域的物种，孤立的孔隙位于较宽的一侧。[此处原文缺失物种名]与[此处原文缺失物种名]和[此处原文缺失物种名]有相似之处，但它的条纹密度明显更高。与[此处原文缺失物种名]相比，它还可以通过条纹形态以及中心区域没有假网纹来区分。[此处原文缺失物种名]由于存在多个孤立的孔隙，在整个属中是独一无二的。
