Abstract

A new species, , was found in the Shun River of Hunan Province, southern China, and its morphology was described based on light and scannning electron microscope obervations. is characterized by its lanceolate valve outline, apiculate valve apices, slightly undulate valve margins, mostly biseriate striae, variable central area, and closed valvocopula. Many abnormal valves of were observed in the samples investigated and the most frequent morphological abnormalities consisted of a lack of symmetry relative to the apical axis caused by a unilateral expansion in the middle part of the valve.

摘要

在中国南方湖南省舜河中发现了一个新物种，并基于光学显微镜和扫描电子显微镜观察描述了其形态。该物种的特征在于其披针形的瓣膜轮廓、具细尖的瓣膜顶端、略呈波浪状的瓣膜边缘、大多为双列的条纹、可变的中心区域以及封闭的瓣膜联结。在所研究的样本中观察到了该物种的许多异常瓣膜，最常见的形态异常包括由于瓣膜中部单侧扩张而导致的相对于顶端轴缺乏对称性。
