根瘤菌“新分化体10”（NC 10）是淡水浮游植物中常见的18 S rRNA基因测序产物。本文描述了一新属和两种真核食双鞭原生生物，Aquavolonhoantrani n.一般的;一般的sp.和双角钝绥螨A. dientrani n.一般的;一般的例如，其代表了NC 10的第一个形态特征成员，在此命名为Aquavolonida ord. nov。轻微代谢的细胞具有裸露的异动鞭毛，其动体彼此成直角，并通过至少一根原纤维连接。与已知的最接近的亲戚Tremula longifila不同，它们在游泳时绕着纵轴旋转，很少在表面上滑行。用谱系特异性PCR引物筛选广泛的环境DNA提取物显示，Aquavolonida由大量的原生生物组成，这些原生生物在淡水浮游生物栖息地中最多样化，但在海洋环境中尚未检测到。水栖动物中较早分支的谱系包括在土壤和淡水沉积物中较少发现的生物。18 S rRNA基因的同源性表明，Aquavolonida形成了一个共同的进化谱系与吸虫和uncharacterized '新的分支12'，这可能是最深的谱系之一，在Rhizaria，独立于Cercozoa（Filosa），Endomyxa，和Retaria。
Rhizarian ‘Novel Clade 10’ (NC10) is frequently detected by 18S rRNA gene sequencing studies in freshwater planktonic samples. We describe a new genus and two species of eukaryovorous biflagellate protists, Aquavolon hoantrani n. gen. n. sp. and A. dientrani n. gen. n. sp., which represent the first morphologically characterized members of NC10, here named Aquavolonida ord. nov. The slightly metabolic cells possess naked heterodynamic flagella, whose kinetosomes lie at a right angle to each other and are connected by at least one fibril. Unlike their closest known relative Tremula longifila, they rotate around their longitudinal axis when swimming and only very rarely glide on surfaces. Screening of a wide range of environmental DNA extractions with lineage‐specific PCR primers reveals that Aquavolonida consists of a large radiation of protists, which are most diversified in freshwater planktonic habitats and as yet undetected in marine environments. Earlier‐branching lineages in Aquavolonida include less frequently detected organisms from soils and freshwater sediments. The 18S rRNA gene phylogeny suggests that Aquavolonida forms a common evolutionary lineage with tremulids and uncharacterized ‘Novel Clade 12’, which likely represents one of the deepest lineages in the Rhizaria, separate from Cercozoa (Filosa), Endomyxa, and Retaria.
