title: Isospora bocamontensis n. sp. (Apicomplexa: Eimeriidae) from the yellow cardinal Gubernatrix cristata (Vieillot) (Passeriformes: Emberizidae) in South America.
abstract: A new coccidian species (Protozoa: Apicomplexa: Eimeriidae) is reported from the endangered yellow cardinal Gubernatrix cristata (Vieillot) in southern Brazil. Isospora bocamontensis n. sp. has oöcysts which are subspheroidal, measure 32.1 × 28.9 μm and have a smooth, bilayered wall c.1.5 μm thick. The micropyle and the oöcyst residuum are absent, but a polar granule is sometimes present. Its sporocysts are ellipsoidal and 17.3 × 12.2 μm in size and contain a half-moon-shaped Stieda body, a prominent, homogeneous substieda body; and a sporocyst residuum composed of a compact mass of granules. The sporozoites have one refractile body and a nucleus.
