In the current study, Isospora sagittulae McQuistion and Capparella, 1992 (Protozoa: Apicomplexa: Eimeriidae) is reported from white-shouldered fire-eyes Pyriglena leucoptera (Vieillot, 1818) in the Atlantic Forest in southeastern Brazil. To date, this coccidian species was described from antbirds in Ecuador and Brazilian Amazon. In this sense, oocysts and measurements of the description of I. sagittulae from Amazonian antbirds were required from the deposit for comparison between samples from the Amazon and Atlantic Forest. The morphology was similar in all aspects, despite the polymorphism associated with the oocyst shape. DNA sequences for the mitochondrial cytochrome c oxidase subunit 1 (cox1) locus of the oocysts had similarity of 100%. Therefore, these strong morphological, molecular, and ecological equivalences ensure the unique identification of I. sagittulae. Finally, this finding reveals the wide distribution of I. sagittulae in the Neotropical region and indicates that other antbirds in the Brazilian Cerrado should disperse I. sagittulae to the Amazon and Atlantic Forest.
在当前研究中，从巴西东南部大西洋森林的白肩火眼鸟（Pyriglena leucoptera，维约洛，1818年）体内发现了1992年麦克奎斯顿和卡帕雷拉描述的箭形等孢球虫（原生动物：顶复门：艾美耳科）。迄今为止，该球虫物种是在厄瓜多尔和巴西亚马逊地区的蚁鸟体内被描述的。从这个意义上说，需要从馆藏中获取亚马逊地区蚁鸟的箭形等孢球虫的卵囊及其描述的测量数据，以便对来自亚马逊地区和大西洋森林的样本进行比较。尽管卵囊形状存在多态性，但在所有方面形态都相似。卵囊线粒体细胞色素c氧化酶亚基1（cox1）基因座的DNA序列相似度为100%。因此，这些强大的形态学、分子学和生态学等效性确保了箭形等孢球虫的独特鉴定。最后，这一发现揭示了箭形等孢球虫在新热带地区分布广泛，并表明巴西塞拉多地区的其他蚁鸟应将箭形等孢球虫传播到亚马逊地区和大西洋森林。
