Abstract
Two new species of Coccidia (Apicomplexa: Eimeriidae) are described from European accipitrid raptors (Falconiformes: Accipitridae). Oöcysts of Caryospora aquilae n. sp. found in faeces of the gold eagle Aquila chrysaetos are subspherical to broad ellipsoidal and measure 43 (40–49) × 37.5 (34–39) μm. Polar granule, oöcyst residuum and micropyle are absent. Each oöcyst contains one spherical to subspherical slightly polygonal sporocyst measuring 23.8 (23–25) × 23.3 (22–25) μm. Stieda and substieda bodies are absent. The sporocyst residuum is composed of numerous small granules less than 0.5 μm in diameter dispersed randomly among the sporozoites. Sporulated oöcysts of Caryospora circi n. sp. from faeces of the marsh harrier Circus aeruginosus are widely oval, measuring 24.5 (23–25) × 21.8 (21–24) μm. A polar granule, oöcyst residuum and micropyle are absent. Each oöcyst contains one spherical to subspherical sporocyst measuring 16.2 (15–17) × 15.6 (15–17) μm. A compact granular, spherical to subspherical sporocyst residuum, 10.4 (10–11) × 8.5 (7–9), was present in 76% of measured sporocysts. In 24% of sporocysts the granules of sporocyst residuum were scattered among the sporozoites.
