Sarcocystinae:Nomina Dubia and available names

Abstract
Summary Examination of the original descriptions of the species ofSarcocystis 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 followingnomina dubia: Because the former type species,Sarcocystis miescheriana, is an indeterminatenomen dubium, we are proposingS. 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 reviwed, and definitions are proposed for the following taxa: for which neotypes1 will be prepared and deposited with designated institutions and curators. A new subfamily, Cystoisosporinae, is created.
