摘要

摘要: 本文报道了采自广西沿海沙质环境的3种中国新记录硅藻门植物，分别为沃氏海生双眉藻（Halamphora woelfeliae Stachura-Suchoples, Enke, Schlie, Schaub, Karsten & R.Jahn）、履沙盘藻（Psammodiscus calceatus Tsuy.Watanabe, Nagumo & Ji.Tanaka）和颗粒爱氏藻（Ehrenbergiulva granulosa (Grunow) A.Witkowski, Lange-Bertalot & Metzeltin）。对3个中国新记录种的形态特征、生态习性和地理分布进行了详细描述，丰富了我国海洋硅藻的生物多样性。

Abstract: During an investigation of marine diatom flora in the sand samples from Guangxi, three species were identified as new records in China, which were Halamphora woelfeliae Stachura-Suchoples, Enke, Schlie, Schaub, Karsten & R.Jahn, Psammodiscus calceatus Tsuy.Watanabe, Nagumo & Ji.Tanaka and Ehrenbergiulva granulosa (Grunow) A.Witkowski, Lange-Bertalot & Metzeltin. Their morphological features, ecological habitats and geographical distribution were described in detail. This study enriched the biodiversity of marine diatoms in China.
