Geographic Distribution: Europe (Austria).
Prevalence: Supperer (1952) found this species in 5% of 130 cattle in Austria.
Morphology: This species has been described by Supperer (1952). The oocysts are 36 to 41 by 26 to 30 u, ovoid, with a flattened small end. There is a micropyle at the small end. The oocyst wall is relatively thick and dark brown. The surface of the oocyst bears numerous small, uniformly distributed protuberances in the form of small, blunt points which give the wall a velvety appearance. An oocyst polar granule and residuum are absent. The sporocysts are elongate ovoid, 14 to 18 by 6 to 8 u, without a Stieda body. A sporocyst residuum is present, usually compact. The sporozoites lie lengthwise in sporocysts, with 2 retractile globules. The sporulation time is 10 to 12 days.
It is possible that E. pellita is a synonym of E. bukidnonensis. However, it differs from it in the velvety appearance described for its oocyst wall; the oocyst wall of E. bukidnonensis has been described as speckled, and as a matter of fact Supperer's drawing of E. pellita looks speckled, too. Other differences are that a sporocyst residuum has not been described in E. bukidnonensis, while E. pellita has a prominent one, and the sporocysts of E. bukidnonensis are somewhat pointed at one end (with a Stieda body?), while those of E. pellita are not.
