Three new coccidian (Apicomplexa, Eimeriidae) species from the sayaca tanager, Thraupis sayaca, from Brazil, are reported in the current study. Isospora sanhaci sp. nov. oocysts are spherical to subspherical, 22.1 × 21.0 μm, with smooth, bilayered wall, ∼1.0 μm. Micropyle, oocyst residuum and polar granule are absent, while Stieda and substieda bodies are present. Sporocysts are elongated, 17.0 × 9.9 μm. Sporocyst residuum is present, sporozoites have one refractile body and a nucleus. Isospora sayacae sp. nov. are spherical to subspherical, 28.9 × 27.4 μm, with smooth, bilayered wall, ∼1.3 μm. Micropyle, oocyst residuum and polar granule are absent, while Stieda and substieda bodies are present. Sporocysts are bottle-shaped, 23.4 × 11.8 μm and containing a sporocyst residuum and sporozoites with one refractile body and a nucleus. Isospora silvasouzai sp. nov. are spherical to subspherical, 25.5 × 22.6 μm, with a smooth, bilayered wall, ∼1.0 μm. Micropyle and oocyst residuum are absent, but one polar granule is present. Sporocysts are pyriform ellipsoidal, 17.6 × 10.5 μm. Stieda and substieda bodies and sporocyst residuum are present and sporozoites have one refractile body and a nucleus.

Isospora cagasebi sp. nov. (Apicomplexa, Eimeriidae) is reported from a bananaquit, Coereba flaveola from Brazil. Oocysts are sub-spherical, 24.9 × 24.5 (23.0–26.1 × 22.6–25.4), with a smooth, bilayered wall ∼1.4 and mean L:W ratio 1.0; micropyle, oocyst residuum and polar granule are absent. Sporocysts are elongate ovoidal, 18.7 × 11.5 (17.6–19.4 × 10.4–12.3), with both Stieda and substieda bodies and mean L:W ratio 1.6; sporocyst residuum present and sporozoites each with 2 refractiles bodies.

Two new coccidian species (Protozoa, Apicomplexa, Eimeriidae) are reported from the saffron finch Sicalis flaveola Linnaeus, 1766, a very common species in South America. Isospora cetasiensis sp. nov. oocysts are subspherical to ellipsoidal, 23.1 × 21.6 μm, with smooth, bilayered wall, ∼1.0 μm. Micropyle, oocyst residuum and polar granule are absent. Sporocysts are ovoidal, 15.1 × 10.9 μm. Stieda body is knob-like and substieda body is rounded. Sporocyst residuum is composed of many scattered granules and spherules of different sizes. Sporozoites are vermiform with one refractile body and a nucleus. Isospora sicalisi sp. nov. oocysts are subspherical to ellipsoidal, 27.5 × 25.2 μm, with a smooth, bilayered wall, ∼1.1 μm. Micropyle, oocyst residuum and polar granule are absent. Sporocysts are ellipsoidal, 17.2 × 11.7 μm. Stieda body is knob-like and substieda body is trapezoidal. Sporocyst residuum is composed of scattered granules and spherules of different sizes. Sporozoites are vermiform with one refractile body and a nucleus.
