本文讨论了Cyclotella (k<s:1> tzing) brachibisson（硅藻科）的“stelligeroid”分类群的瓣形态和超微结构。这些分类群具有边缘的多孔孔和边缘孔孔(e)，位于边缘之间。由于这一特征和其他所讨论的特征不符合目前对Cyclotella (k<s:1> tzing) br<s:1> bisson nom. cons.的描述，因此建议将这些分类群正式转移到一个新属Discostella gen. nov.。
The valve morphology and ultrastructure of the the so-called “stelligeroid” taxa of the genus Cyclotella (Kützing) Brébisson (Bacillariophyceae) are discussed. These taxa have marginal mltoportulae and the rimoportula(e) positioned between costae. As this and other discussed characters do not fit the current description of the genus Cyclotella (Kützing) Brébisson nom. cons., the formal transfer of these taxa into a new genus, Discostella gen. nov., is proposed.
