A new isosporan parasite, Isospora iridosornisi, is identified from the fecal contents of the yellow-throated tanager, Iridosornis analis, from Peru. Sporulated oocysts are ovoidal, 22.1 × 18.9(20-25 × 16-23) µm with a smooth, colorless, bilayered wall; the inner wall is darker than the outer wall. The average shape index is 1.2. No micropyle or oocyst residuum are present but the oocyst contains one ovoid polar granule. Sporocysts are ovoid, 13.6 × 9 (9-17 × 8-11) µm with a smooth single layered wall and an average shape index of 1.5. The Stieda body is bubble-shaped with a collar-shaped substieda body. Within the sporocyst is a large spherical residuum composed of coarse non-uniform granules and 4 randomly arranged vermiform sporozoites with a subspherical, posterior refractile body and a centrally located nucleus.
