Note on the Taxonomy of Frenkelia microti (Findlay & Middleton, 1934) (Apicomplexa: Sarcocystidae).

Based on biological, morphological and molecular data, species of Frenkelia Biocca, 1968 should be reclassified within the genus Sarcocystis Poche, 1913. This taxonomic change leads to the secondary homonymy of S. microti (Findlay & Middleton, 1934) n. comb. and S. microti Dubey, 1983. The recently suggested conspecificity and consequent synonymy of S. microti (Findlay & Middleton, 1934) and S. buteonis (Henry, 1932) is not really justifiable and thus S. microti (Findlay & Middleton, 1934) should be considered a valid species. S. jaypeedubeyi nom. nov. is, therefore, proposed as a nomen novum for S. microti Dubey, 1983 to alleviate the problem of this secondary homonymy.
