蚜虫仍然是鲜为人知的藻类寄生蜂，但由于它们位于全菌门的系统发育位置，最近引起了相当大的兴趣。它们与隐菌门（Rozellosporidia）和微孢子虫门一起，最近被重新分类为后孢子菌门（Opisthosporidia），构成全菌门内真菌的姐妹群。分子环境研究揭示了蚜虫的巨大多样性，但仅描述了四个属：蚜虫属、变形虫属、拟疟疾属和假疟疾属。在这里，我们描述了蚜虫新代表 Paraphelidium letcheri sp 的生命周期。 11月，并提供该物种的18S rRNA基因序列。分子系统发育分析表明，P. letcheri 是 Paraphelidium tribonemae 的姐妹，它们一起形成一个单系簇，与具有鞭毛游动孢子的 Aphelidium 和具有变形虫游动孢子的变形虫有远缘关系。
Aphelids remain poorly known parasitoids of algae and have recently raised considerable interest due to their phylogenetic position at the base of Holomycota. Together with Cryptomycota (Rozellosporidia) and Microsporidia, they have been recently re-classified as the Opisthosporidia, which constitutes the sister group to the fungi within the Holomycota. Molecular environmental studies have revealed a huge diversity of aphelids, but only four genera have been described: Aphelidium, Amoeboaphelidium, Paraphelidium, and Pseudaphelidium. Here, we describe the life cycle of a new representative of Aphelida, Paraphelidium letcheri sp. nov., and provide the 18S rRNA gene sequence for this species. Molecular phylogenetic analysis indicates that P. letcheri is sister to Paraphelidium tribonemae and together they form a monophyletic cluster which is distantly related to both, Aphelidium, with flagellated zoospores, and Amoebaphelidium, with amoeboid zoospores.
