The tectiform loricate choanoflagellate genera Calotheca, Stephanacantha and Syndetophyllum have all been first described from warm water habitats and share the presence of flattened and often elaborate costal strips in the lorica. The current reinvestigation does confirm both the widespread occurrence of these taxa within the global warm water belt, and largely corroborates the established genus and species matrix. We describe here Stephanacantha oceanica sp. nov. which closely resembles S. campaniformis, and transfer Parvicorbicula zigzag to the genus Stephanacantha, despite differences in costal strip morphology, but based on a complete agreement in lorica constructional details.
栉壳质领鞭毛虫属的 Calotheca、Stephanacantha 和 Syndetophyllum 这几个形态属都首次在暖水生境中被描述，它们的共通特征是具扁平且通常复杂的肋条在鞘上。当前的重新研究确实确认了这些分类单元在全球暖水带的广泛存在，并在很大程度上证实了已建立的属和种矩阵。我们在此描述了与 S. campaniformis 非常相似的 Stephanacantha oceanica sp. nov.，尽管肋条形态存在差异，但根据鞘结构细节的完全一致，我们将 Parvicorbicula zigzag 转移到 Stephanacantha 属中。
