Lake Qinghai is an ancient brackish water lake in which several endemic diatom species have been discovered. In this study, a species of is observed under light and scanning electron microscopy and described as new, The living cells of always lie in girdle view due to the cell depth being much larger than valve width (3.3-8.8 vs. 2.0-3.0 μm). The valves of are characterized by their narrow, linear-lanceolate outline, with capitate to subcapitate apices, the presence of two rimoportulae, one at each apex, embedded in the last rib or located among striae and a 4:2 configuration of girdle bands in normal vegetative cells, with four bands assigned to the epivalve and two to the hypovalve. The new taxon is compared with similar species from the genera and .
青海湖是一个古老的咸水湖，在其中发现了几种地方性硅藻物种。在本研究中，在光学显微镜和扫描电子显微镜下观察到一种物种，并将其描述为新物种。由于细胞深度远大于瓣片宽度（3.3 - 8.8微米对2.0 - 3.0微米），该物种的活细胞总是呈带面观。该物种的瓣片特征在于其狭窄的、线状披针形轮廓，顶端为头状至近头状，在每个顶端有两个缘孔，一个嵌入最后一条肋或位于条纹之间，正常营养细胞中的带纹呈4:2配置，四个带纹属于上壳，两个属于下壳。将这个新分类单元与来自[相关属名未给出]属的相似物种进行了比较。
