Original host: Crocidura russula (Hermann, 1780) (Syn. C. aranea [?]), Greater white-toothed shrew.

Remarks: This description was published in a short paragraph with no figure. Oocysts were subspheroid, 16 x 12.7 with a very small micropyle and sporocysts were ovoid, 7.5 x 6. No other structural or qualitative information was given for the sporulated oocyst. There also was great confusion about the correct identity of the host as discussed by Levine and Ivens (1979). For these reasons, this species must be regarded as a species inquirendae.
