Loricate choanoflagellate genera that incorporate flattened costal strips in the lorica (i.e. Calotheca, Stephanacantha, Thomsenella (= Platypleura) and Syndetophyllum) are prevalent in warm water habitats. The genus Thomsenella (=Platypleura) thus comprises four species and three of these have an Andaman Sea type locality. Our ongoing examination of loricate choanoflagellate material from all major warm water oceans has provided us with the opportunity of revisiting species of Thomsenella in order to test and fortunately verify, in a morpho-specific context, the robustness of the species matrix initially defined.

含鞭毛平坦的肋条的鞭毛鞭毛藻属属（即Calotheca，Stephanacantha，Thomsenella（= Platypleura）和Syndetophyllum）在温暖的水生环境中盛行。因此，Thomsenella属（= Platypleura）包含四个物种，其中三个具有安达曼海类型的位置。我们正在进行的对所有主要温水海洋中的鞭毛鞭毛材料的研究，为我们提供了重新审视沙门氏菌物种的机会，以便在特定形态的背景下测试并幸运地验证最初定义的物种矩阵的稳健性。
