摘 要 ：2004~2006年,对武汉东湖的底栖藻类进行了生态学调查研究。在对底栖硅藻的定性和定量研究中,发现了一种中心纲种类为中国新记录,它具有一些海洋角盘藻科种类的特征,如眼纹斑(Ocellus)等。经鉴定为光滑侧链藻Pleurosira laevis(Ehrenberg) Compere。参考Compere 1982年的研究,我们同意他的看法,即以前在我国台湾发现的台湾多变筒藻Proteucylindrus taiwanensis Li et Chiang和广东发现的Cerataulus laevis var.?chinensis Grunow也应归于侧链藻属(Pleurosira),名称为索科特拉侧链藻Pleurosira socotrensis(Kitton) Compere。

Abstract:A new record centric diatom was found from Donghu Lake,Wuhan during the periphyton ecology investigation in 2004-2006,it shows close affinity to those of marine Eupodiscaceae species because of remarkable ocellus.As result,it is Pleurosira laevis(Ehrenberg)Compere.According to the study of Compere in 1982,we agreed that the name of Proteucylindrus taiwanensis Li et Chiang from Taiwan and Cerataulus laevis var. chinensis Grunow from Guangdong should be moved into this genus as P.socotrensis(Kitton)Compere.So,both species of Pleurosira were found from China.
