Aided by an extensive collection of specimens from warm water seas, it has been possible to revisit the loricate choanoflagellate genus Cosmoeca. While the type species C. norvegica and also C. ventricosa sensu stricto have been described from temperate North Atlantic realms and share a cosmopolitan distribution, the remaining species and morphotypes of Cosmoeca are largely confined to warmer waters. The new data broadly validates the initial circumscription of species of Cosmoeca. The persisting taxonomic puzzle with respect to C. ventricosa, which in addition to the core type accommodates no less than five different morphotypes (form A–E), has been further elucidated. The Cosmoeca paper is part of a ‘monographic’ series of warm water loricate choanoflagellate contributions in progress, where the aim is to provide the best possible account of warm water species diversity, based on traditional light and electron microscopical techniques, as a tool for future identification work based on microscopy, and in support of the work in progress with establishing a quality assured molecular tool for future recognition of diversity.

在温暖的海水中收集大量标本的帮助下，有可能重新审视了鞭毛鞭毛藻科（Cosmoeca）。虽然已经从北大西洋温带地区描述了C. norvegica和C.ventricosa sensu stricto类型的物种，并且它们具有世界性的分布，但Cosmoeca的其余物种和形态类型主要限于温暖的水域。新数据广泛地验证了科斯莫卡物种的初始界限。相对于该持续分类难题C.萼，其中在除了核心类型容纳超过五个不同形态型（晶型A-E）无以下，得到了进一步的阐明。的Cosmoeca纸是正在进行的“专题”系列温水卤代胆囊酸盐研究的一部分，其目的是基于传统的光和电子显微镜技术，为暖水物种多样性提供最佳的解释，作为未来鉴定的工具以显微镜为基础的工作，并为建立正在进行中的工作提供支持，以建立一种有质量保证的分子工具，以供将来识别多样性。
