A new species of coccidia (Protozoa: Apicomplexa: Eimeriidae) found parasitizing the white-eyed parakeet Psittacara leucophthalmus (Müller, 1776) in Brazil is described. Eimeria psittacarae n. sp. has oocysts that are ellipsoidal, 34.8 × 24.3 μm, with smooth, bilayered wall, ~1.7 μm thick. Micropyle present. Oocyst residuum absent, but one or two polar granules are present. Sporocysts are elongate ellipsoidal, 19.2 × 9.7 μm. Stieda body knob-like and sub-Stieda body rounded. Sporocyst residuum is composed of granules that appear to be membrane-bounded. Sporozoites are vermiform with one refractile body and a nucleus. This is the sixth description of an eimeriid coccidium parasitizing a New World psittacine.
本文描述了在巴西发现的一种寄生于白眼鹦哥（Psittacara leucophthalmus (Müller, 1776)）体内的新球虫（原生动物：顶复门：艾美耳科）。新种艾美耳球虫（Eimeria psittacarae n. sp.）的卵囊呈椭圆形，大小为34.8×24.3μm，壁光滑，双层，厚约1.7μm。有微孔。无卵囊残体，但有一或两个极粒。孢子囊呈长椭圆形，大小为19.2×9.7μm。斯氏体呈瘤状，亚斯氏体呈圆形。孢子囊残体由似乎有膜包被的颗粒组成。子孢子呈蠕虫状，有一个折光体和一个细胞核。这是对寄生于新大陆鹦鹉的艾美耳科球虫的第六次描述。
