The loricate choanoflagellate genera Diaphanoeca Ellis and Crinolina Thomsen encompass a total of ten species. The majority of these are recorded from the warm water regions reported on here. A distinct morphological dichotomy characterizes the genus Diaphanoeca as currently circumscribed. The species distribute themselves within a ‘D. grandis subgroup’ and a ‘D. pedicellata subgroup’ distinguished on e.g., the position of the protoplast inside the lorica chamber and the elaboration of the anterior projections. We are, while awaiting in particular further molecular evidence, taking a conservative approach and abstain from dealing with the subgroup issue at the generic level. The examination of material from the warm water regions of the world’s oceans has resulted in the description of D. sargassoensis sp.n., D. pseudoundulata sp.n., and D. throndsenii sp.n., and a thorough re-examination of D. undulata. Species of Crinolina share multiple features with in particular the D. grandis species subgroup. It is yet relevant, both in a morphological and molecular perspective, to retain the genus Crinolina which remains unambiguously defined based on the posteriorly open lorica. A high level of agreement is found when contrasting morphological and molecular based phylogenetic schemes.

来自温水海洋的 Loricate choanoflagellates (Acanthoecida)。八。Crinolina Thomsen 和 Diaphanoeca Ellis

loricate choanoflagellate 属Diaphanoeca Ellis 和Crinolina Thomsen 共有十个物种。其中大部分记录来自此处报告的温水区域。一个独特的形态二分法表征了目前所界定的Diaphanoeca属。该物种分布在“ D. grandis亚群”和“ D. pedicellata”中亚组的区别在于,例如,原生质体在 lorica 室内的位置和前部投影的制作。我们在等待特别是进一步的分子证据的同时,采取保守的方法,避免在通用水平上处理亚组问题。对来自世界海洋温水区的材料的检查导致对D. sargassoensis sp.n.、D . pseudoundulata sp.n.和D. throndsenii sp.n. 的描述,并进行了彻底的重新检查的D. undulataCrinolina物种与D. grandis具有多种特征种亚群。从形态学和分子角度来看,保留Crinolina属仍然是相关的,该属仍然基于后部开放的 lorica 明确定义。当对比基于形态学和分子的系统发育方案时,发现高度一致。
