Marssoniella elegans Lemmermann, 1900, a parasite of ovarial tissues of the copepod Cyclops vicinus Uljanin, 1875, was studied as a representative of aquatic-clade microsporidia which form "heteroinfectious spores" (spores not infective to the original host as opposed to "homoinfectious spores" which are infective for the original host) and which thus should require an alternate host. Several structural characters of this microsporidian are similar to those of copepod morphs of microsporidia infecting mosquitoes. However, small subunit ribosomal DNA phylogeny indicates that caddis flies (Insecta, Trichoptera) might be the alternate hosts of Marssoniella. Ultrastructural data obtained are used to redefine the genus Marssoniella Lemmermann, 1900 and its type species Marssoniella elegans.
秀丽马尔索尼亚虫（Marssoniella elegans Lemmermann，1900）是桡足类独眼剑水蚤（Cyclops vicinus Uljanin，1875）卵巢组织的寄生虫，作为水生类微孢子虫的代表进行了研究。该类微孢子虫形成“异感染性孢子”（与对原始宿主具有感染性的“同感染性孢子”相反，对原始宿主无感染性的孢子），因此应该需要一个替代宿主。这种微孢子虫的几个结构特征与感染蚊子的微孢子虫的桡足类形态相似。然而，小亚基核糖体DNA系统发育表明，毛翅目昆虫（昆虫纲，毛翅目）可能是秀丽马尔索尼亚虫的替代宿主。所获得的超微结构数据用于重新定义1900年的马尔索尼亚虫属（Marssoniella Lemmermann）及其模式种秀丽马尔索尼亚虫（Marssoniella elegans）。
