A microsporidian parasite infecting the pheasantshell mussel, Actinonaiais pectorosa, was discovered in a freshwater system in the USA. The original description of this species placed it into the holding genus "Microsporidium"; however, the availability of ecological, environmental, histological, electron microscopy, and genetic data, suffice to provide a complete formal taxonomic account of this species. In this note, the genus Knowlespora n. gen. is erected and described to hold the type species: Knowlespora clinchi gen. et comb. nov., originally described as 'Microsporidium clinchi'. A discussion is presented to suggest that this novel species is unlikely to be closely related to other molluscan microsporidians (all of which lack genetic data, to date) and highlights the diversity of oocyte-infecting species across the Microsporidia.
在美国的一个淡水系统中发现了一种感染褶纹冠蚌（Actinonaiais pectorosa）的微孢子虫寄生虫。该物种的最初描述将其归入“微孢子虫属（Microsporidium）”；然而，生态、环境、组织学、电子显微镜和遗传数据足以提供该物种完整的正式分类描述。在本说明中，建立并描述了诺氏微孢子虫属（Knowlespora n. gen.），以容纳模式种：克林奇诺氏微孢子虫（Knowlespora clinchi gen. et comb. nov.），最初被描述为“克林奇微孢子虫（Microsporidium clinchi）”。本文进行了讨论，表明这种新物种不太可能与其他软体动物微孢子虫密切相关（迄今为止，所有其他软体动物微孢子虫均缺乏遗传数据），并强调了微孢子虫中感染卵母细胞物种的多样性。
