Abstract

Nupela giluwensis Vyverman & Compére 1991 has been found in the aquatic ecosystem of Vietnam for the first time. The main qualitative (valve shape, shape of valve ends, and morphology of striae) and quantitative (length, breadth, and striae density) data are studied. A comparison of the valves of the Vietnamese population and typical population show their morphological and ultrastructural resemblance. Our valves differ from valves of the type species by less capitate ends and 1–3 longitudinal rows of areolae on the of the valve face. The species is illustrated by original LM and SEM microphotographs.

硅藻Nupela giluwensis的分布和形态扩展

摘要

越南水生生态系统中首次发现了Nupela giluwensis Vyverman＆Compére1991。研究了主要定性数据（阀门形状，阀端形状和条纹形态）和定量数据（长度，宽度和条纹密度）。越南种群与典型种群的瓣膜比较表明它们的形态和超微结构相似。我们的阀门与同类阀门的区别在于：其头端较少，且在阀门表面上有1-3个纵向的乳晕纵向排。该物种通过原始的LM和SEM显微照片进行了说明。
