Remarks: The 1956 paper by Agostinucci, in which he decribes this species again, is identical to the 1955 paper. This species also was reported in 3/10 (30%) T. europaea by Golemansky (1979) from the Sreburna Reserve in Bulgaria. The oocysts he found were 12.5-13.8 x 10-11; sporocysts were 10-13 x 5.4-7.6.
