The main outcome of this and subsequent papers is to provide a baseline survey of heterotrophic protist diversity from warm water marine ecosystems, exemplified by loricate choanoflagellates (Acanthoecida). Loricate choanoflagellates are heterotrophic, nano-sized protists that are ubiquitous in marine and brackish water habitats. They dwell in a lorica formed by silicified costal strips organized in species specific patterns. The single anteriorly directed flagellum is surrounded by a collar formed by microvilli which together constitute the feeding apparatus. Keystone benefits from this warm water survey, which covers all three major oceans, is an improved understanding of global biogeographical patterns, and a further consolidation of the morphospecies matrix, that constitutes a highly essential reference framework for the current efforts to provide barcodes for as many species of loricate choanoflagellates as possible, based on e.g. single cell pipetting techniques. We describe here Conioeca gen. et sp. nov., which is so far distributionally confined to warm water habitats, and elaborate on the morphological variability encountered within the N. minuta complex. This leads to both the circumscription of a new N. minuta form A as well as the description of N. mexicana sp. nov.
本文及后续论文的主要成果是为暖水海洋生态系统中的异养原生生物多样性提供基线调查，以具鞘有孔虫（Acanthoecida）为例。具鞘有孔虫是异养的纳米级原生生物，在海洋和半咸水栖息地中普遍存在。它们生活在由硅化的肋条以物种特异性模式组成的鞘中。唯一向前指向的鞭毛被微绒毛组成的领围绕，共同构成了摄食器官。本项暖水调查的主要益处是增进了对全球生物地理格局的理解，并进一步巩固了形态种矩阵，这是当前努力为尽可能多的具鞘有孔虫物种提供条形码的重要参考框架，例如基于单细胞移液技术。我们在这里描述了 Conioeca gen. et sp. nov.，它目前仅分布在暖水栖息地，并详细阐述了在 N. minuta 复合体中遇到的形态变异性。这导致了新的 N. minuta 形式 A 的划定以及 N. mexicana sp. nov. 的描述。
