Fifteen fecal samples from peacocks (Pavo cristatus) in Saudi Arabia contained oocysts of Eimeria riyadhae n. sp. in two peacocks and oocysts of E. arabica n. sp. in one peacock. Sporulated oocysts of Eimeria riyadhae are ellipsoidal, 27-30.5 x 20.5-25 (28.8 +/- 1.3 x 22.4 +/- 1.6) micron, with a two-layered wall and bilobed polar body, but without a micropyle or residuum. The sporocysts are ovoid, 11-14.5 x 6.5-8 (13.2 +/- 1.2 x 7.2 +/- 0.6) micron with a thick, knob-like Stieda body and a residuum. Sporulated oocysts of Eimeria arabica are spheroidal, 17.5-21.5 x 17.5-21.5 (19.2 +/- 1.6 x 19.2 +/- 1.6) micron, with a two-layered wall and two refractile polar bodies, but without a micropyle or residuum. The sporocyts are elongate ovoid, 9.5-12 x 4-6.5 (11.2 +/- 0.9 x 5.5 +/- 0.88), with a small crescent-shaped Stieda body. The host bird belongs to the order Galliformis.
来自沙特阿拉伯孔雀（孔雀雉）的15份粪便样本中，两份样本含有利雅得艾美球虫（新种）的卵囊，一份样本含有阿拉伯艾美球虫（新种）的卵囊。利雅得艾美球虫的孢子化卵囊呈椭圆形，大小为27 - 30.5×20.5 - 25（28.8±1.3×22.4±1.6）微米，有两层壁和双叶极体，但无微孔或残体。孢子囊呈卵形，大小为11 - 14.5×6.5 - 8（13.2±1.2×7.2±0.6）微米，有一个厚的、瘤状的斯氏体和一个残体。阿拉伯艾美球虫的孢子化卵囊呈球形，大小为17.5 - 21.5×17.5 - 21.5（19.2±1.6×19.2±1.6）微米，有两层壁和两个折光极体，但无微孔或残体。孢子囊呈长卵形，大小为9.5 - 12×4 - 6.5（11.2±0.9×5.5±0.88），有一个小的新月形斯氏体。宿主鸟类属于鸡形目。
