Holocarpic oomycetes are poorly known but widespread parasites in freshwater and marine ecosystems. Most of the holocarpic species seem to belong to clades that diverge before the two crown lineages of the oomycetes, the and the . Recently, the genus was described to accommodate , a holocarpic parasitoid of diatoms, which received varying support for its placement as the earliest-diverging oomycete lineage. In the same phylogenetic reconstruction, was grouped with some somewhat divergent sequences derived from environmental sequencing, indicating that would not remain monotypic. Here, a second species of is reported, which was found as a parasitoid in the limnic centric diatom . Its life-cycle stages are described and depicted in this study and its phylogenetic placement in the genus revealed. As a consequence, the newly discovered species is introduced as .
全果卵菌是鲜为人知但在淡水和海洋生态系统中广泛存在的寄生虫。大多数全果物种似乎属于在卵菌的两个冠群谱系（即 和 ）之前分化的进化枝。最近，描述了 属以容纳 ，一种硅藻的全果寄生蜂，其作为最早分化的卵菌谱系的位置得到了不同程度的支持。在同一系统发育重建中， 与一些来自环境测序的略有差异的序列归为一组，这表明 不会保持单型。在此，报道了 的第二个物种，它被发现是湖泊中心硅藻 中的一种寄生蜂。本研究描述并描绘了其生命周期阶段，并揭示了其在 属中的系统发育位置。因此，新发现的物种被命名为 。
