Original host: Sorex araneus Linnaeus, 1758 (Syn. S. vulgaris), Eurasian common shrew.

Remarks: This description was published as a note under observations on some animal parasites from Czechslovakia. Oocysts were ovoid, 50 x 30, with a slightly flattened, very small M; sporocysts were spheroid, ~20; SP were 10 x 9. His description lacked qualitative detail and there was no line drawing and/or photomicrograph of a sporulated oocyst. This form, therefore, must be regarded as a species inquirendae. The only other time this "species" was mentioned was when Frank (1978) said she found it in S. araneus in Austria.
