Abstract

ABSTRACT Despite more than 150 years of diatom research in India, cymbelloid taxa have rarely been investigated when compared to the other parts of the world. A new freshwater species of Encyonema Kützing was discovered from the mountain ranges of Peninsular India and is described based on light and scanning electron microscopy observations. This paper provides a comparison of the new taxa with morphologically similar taxa of the genus Encyonema. Encyonema keshrii, sp. nov., is characterized on the basis of distinctive morphological characters including valve and apex shape as well as striae density. Enccyonema keshrii, sp. nov., is found to be a wide spread taxon with distribution across the Eastern Ghats, Western Ghats and the Eastern Himalayas of Indian subcontinent.

印度次大陆一硅藻新种(小叶藻门，硅藻科)

尽管在印度进行了150多年的硅藻研究，但与世界其他地区相比，小叶藻分类群很少被调查。在印度半岛的山脉中发现了一种新的淡水Encyonema k tzing，并根据光学和扫描电子显微镜观察进行了描述。本文将这一新分类群与形态学上相似的Encyonema属分类群进行了比较。keshrii, sp. nov.具有独特的形态特征，包括阀形和先端形状以及条纹密度。Enccyonema keshrii, sp. nov.是一个分布广泛的分类群，分布在印度次大陆的东高止山脉、西高止山脉和东喜马拉雅山脉。
