Synonym: Eimeria hones si Landers, 1952.
Location: Unknown. Oocysts found in feces.
Geographic Distribution: North America (Wyoming).
Prevalence: Landers (1952) found this species in 2 of 9 sheep in Wyoming.
Morphology: This species has been described by Landers (1952). The oocysts are subspherical, 18 to 25 by 16 to 21 u with a mean of 21.2 by 17.7 u. Their length-width ratio is 1.1 to 1.3 with a mean of 1.20. The oocyst wall has conspicuous, uniform, cone-shaped pits about 0.5 u in diameter. It is 1.2 to 1.8 u thick (mean, 1.5 u); its outer layer is colorless to yellowish, and its inner layer greenish, with two dark refraction lines, one at either surface. There is a conspicuous micropyle. A micropylar cap is present, sometimes imperceptible, up to 6.5 u wide and 1.6 u high with a mean of 4.1 by 0.8 u. An oocyst residuum and oocyst polar granule are absent. The sporocysts are spherical to ellipsoidal, and average 8.1 u in diameter or 10.4 by 6.9 u. The presence or absence of a sporocyst residuum was not mentioned.
