Abstract

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.
