Geographic Distribution: India (Bombay).
Prevalence: Hiregaudar (1956) described this species from a single calf.
Morphology: The oocysts are ovoid, 36 to 38 by 25 to 28 u. The oocyst wall is 0.3 u thick, slightly thicker toward micropylar end, smooth, transparent, and pale yellow or yellow. The micropyle is distinct, 0.5 u in diameter. The sporocysts are oval, 15 to 9 u, thinning at the pointed end. The sporozoites are 4 to 6 by 1 to 3 u and finely granular. An oocyst residuum and polar granule are absent. A sporocyst residuum is present. The sporulation time is 1 to 2 days during the summer. The extremely thin wall and the tiny, distinct micropyle may differentiate this species from other bovine coccidia. However, the possibility must not be overlooked that these oocysts may be those of a species such as E. bukidnonensis from which the thick, brittle outer wall has cracked off.
Life Cycle: Unknown.
