Isospora basileuterusi n. sp. (Apicomplexa: Eimeriidae) from the golden-crowned warbler Basileuterus culicivorus (Deppe) (Passeriformes: Parulidae) in South America.

ABSTRACT: Isospora basileuterusi Mello & Berto n. sp. is described based on material from the golden-crowned warbler Basileuterus culicivorus (Deppe) captured in the Itatiaia National Park (Parque Nacional do Itatiaia), a conservation unit in south-eastern Brazil. Oöcysts of the new species are ellipsoidal to ovoidal, measuring on average 25.2 × 21.1 μm, with a smooth, bi-layered wall, c.1.6 μm thick. Micropyle and oöcyst residuum are both absent, but one to three polar granules are present. Sporocysts are ellipsoidal to lemon-shaped, measuring on average 15.3 × 9.5 μm, with a knob-like Stieda body and a trapezoidal sub-Stieda body. Sporocyst residuum is present, usually as a body of membrane-bound granules. Sporozoites are vermiform, with refractile bodies. Four of the 19 warbl
