A new species of coccidia (Protozoa: Apicomplexa: Eimeriidae) found parasitizing the yellow-legged thrush Turdus flavipes (Vieillot, 1818), the pale-breasted thrush Turdus leucomelas Vieillot, 1818 and the creamy-bellied thrush Turdus amaurochalinus Cabanis, 1850 in Southeastern Brazil is described. Isospora brasilsatoae n. sp. has oocysts that are ovoidal to pyriform, 26.8 × 21.1 μm, with smooth, bilayered wall, ~1.6 μm thick. Micropyle present. Oocyst residuum absent, but one to three polar granules are present. Sporocysts are elongate ovoidal, 18.1 × 10.5 μm. Stieda body knob-like and sub-Stieda body trapezoidal. Sporocyst residuum is composed of granules that appear to be membrane-bounded. Sporozoites are vermiform with refractile bodies and striations. This is the ninth description of an Isospora sp. parasitizing a New World thrush.
描述了一种新的球虫（原生动物：顶复门：艾美耳科），它寄生于巴西东南部的黄腿鸫（Turdus flavipes，维约洛，1818年）、淡胸鸫（Turdus leucomelas，维约洛，1818年）和乳腹鸫（Turdus amaurochalinus，卡巴尼斯，1850年）。巴西索托伊氏等孢球虫（Isospora brasilsatoae）新种的卵囊呈卵形至梨形，大小为26.8×21.1μm，壁光滑，双层，厚约1.6μm。有微孔。无卵囊残体，但有1至3个极粒。孢子囊呈细长卵形，大小为18.1×10.5μm。斯氏体呈瘤状，亚斯氏体呈梯形。孢子囊残体由似乎有膜包被的颗粒组成。子孢子呈蠕虫状，有折光体和条纹。这是对寄生于新大陆鸫的等孢球虫属的第九次描述。
