Examination of the original descriptions of the species of Sarcocystis in cattle, sheep, and swine, and of isosporid oocysts shed sporulated by dogs, cats, man, and other carnivores, has shown that it is not possible in most instances to identify unambiguously recently recognized taxa. The original descriptions are insufficient, and because no type specimens exist, could apply to two or more of the presently recognized taxa. We consider the following nomina dubia: Sarcocystis hirsuta S. miescheriana S. tenella S. cruzi S. bertrami Isospora bigemina (S. bigemina) I. hominis (S. hominis) I. buteonis (Frenkelia buteonis) Because the former type species, Sarcocystis miescheriana, is an indeterminate nomen dubium, we are proposing S. muris as the new type species. Historically, it was the first species described clearly and unambiguously even in the light of present knowledge, and the stages of its life cycle are probably completely known; it was the second species to be named. Old and recent descriptions are reviewed, and definitions are proposed for the following taxa: S. bovifelis S. bovicanis S. bovihominis S. ovifelis S. ovicanis S. muris (type species) S. suihominis S. suicanis S. equicanis Frenkelia microti F. glareoli for which neotypes will be prepared and deposited with designated institutions and curators. A new subfamily, Cystoisosporinae, is created.
对牛、羊和猪体内的肉孢子虫物种以及犬、猫、人及其他食肉动物排出的已孢子化的等孢球虫卵囊的原始描述进行研究后发现，在大多数情况下，无法明确鉴定最近确认的分类单元。原始描述不够充分，而且由于不存在模式标本，可能适用于目前确认的两个或更多分类单元。我们认为以下为疑名：多毛肉孢子虫、米氏肉孢子虫、柔嫩肉孢子虫、克鲁斯肉孢子虫、伯特拉米肉孢子虫、双芽等孢球虫（牛等孢球虫）、人等孢球虫（人肉孢子虫）、鹰等孢球虫（弗伦克隐孢球虫）。由于前模式种米氏肉孢子虫是一个不确定的疑名，我们提议将鼠肉孢子虫作为新模式种。从历史上看，即使根据目前的知识，它也是第一个被清晰明确描述的物种，其生命周期阶段可能已完全为人所知；它是第二个被命名的物种。本文回顾了过去和近期的描述，并为以下分类单元提出了定义：牛猫肉孢子虫、牛犬肉孢子虫、牛人肉孢子虫、羊猫肉孢子虫、羊犬肉孢子虫、鼠肉孢子虫（模式种）、猪人肉孢子虫、猪犬肉孢子虫、马犬肉孢子虫、微小弗伦克隐孢球虫、格氏弗伦克隐孢球虫，将为这些分类单元制备新模标本并保存在指定的机构和标本管理人处。创建了一个新亚科，即囊等孢亚科。
