title: Two new Isospora species from Brazilian tanager (Ramphocelus bresilius dorsalis) of South America.
abstract: Two new coccidian (Protozoa: Apicomplexa: Eimeriidae) species from the Brazilian tanager Ramphocelus bresilius dorsalis are reported in the current study. Isospora cadimi n. sp. oocysts are spheroidal to sub-spheroidal, 24.2 x 22.9 microm, with a smooth and bi-layered wall, approximately 1.1 microm. Micropyle, oocyst residuum, and polar granule are absent. Sporocysts are broadly ovoidal, 16.9 x 11.6 microm. Stieda and substieda bodies are present. Sporocyst residuum is present and sporozoites have refractile body and nucleus. Isospora navarroi n. sp. oocysts are spheroidal to sub-spheroidal, 21.4 x 20.6 microm, with a smooth and bi-layered wall, approximately 1.1 microm. Micropyle, oocyst residuum, and polar granule are absent. Sporocysts are ellipsoidal, 16.1 x 10.2 microm. Stieda and substieda bodies are present. Sporocyst residuum is present and sporozoites have a robust posterior refractile body.
