Eimeria idmii n. sp. (Apicomplexa: Eimeriidae) from the Arabian Mountain gazelle, Gazella gazella in Saudi Arabia. Journal of the Helminthological Society of Washington, 59: 120-124.

ABSTRACT: Fecal examination of 47 idmi, the Arabian or dark-colored mountain gazelle, Gazella gazella Pallas,
1766, at King Khalid Wildlife Research Center in Thumamah, Riyadh Province, Saudi Arabia, yielded oocysts
of an undescribed coccidian, Eimeria idmii sp. n. Sixteen of the 47 idmi (34%) were infected. Sporulated oocysts
of E. idmii sp. n. are ellipsoidal, flattened at micropylar end, 42 x 30 (36-48 x 27-37) urn., length/width ratio
1.4 (1.2-1.6), with smooth, double-layered oocyst wall, the inner yellow, the outer green, with micropyle covered
with dome-shaped micropylar cap, 9 (2-15) /^m wide, 2 (1—4) /urn high. Sporocysts elongate, ovoidal, 18 x 10
(10-23 x 8-13) ^m with Stieda body and sporocyst residuum. Sporozoites elongate, 15 x 6(10-18 x 4-9) ^m,
each with a large and a small refractile body, 5 (3-8) nm and 3 (1-5) nm in diameter, respectively. Sporulation
time 7-8 days at 25 ± 2°C.
