Apusomonadida (apusomonads) is a group of heterotrophic biflagellates that feed on bacteria and small protists. Their diversity is not fully understood, and several major lineages remain to be identified in natural environments. Here, we report Podomonas kaiyoae n. sp., which was isolated from deep-sea sediment and can be maintained as an axenic culture. While P. kaiyoae branched within one of the major unidentified lineages, the combination of the morphological characteristics is generally similar to that of Podomonas species, but can be distinguished from that of other Podomonas species based on the cell sizes.
动质体目（动质体）是一类以细菌和小型原生生物为食的异养双鞭毛虫。它们的多样性尚未完全被了解，在自然环境中仍有几个主要谱系有待确定。在此，我们报告了从深海沉积物中分离出的开洋波豆虫新种，它可以作为无菌培养物进行保存。虽然开洋波豆虫在一个主要的未确定谱系中分支，但形态特征的组合总体上与波豆虫属物种相似，但基于细胞大小可与其他波豆虫属物种区分开来。
