Two new species of Caryospora Leger, 1904 (Apicomplexa, Eimeriidae) from accipitrid raptors

Two new species of Coccidia (Apicomplexa: Eimeriidae) are described from Eu ropean accipitrid raptors (Falconiformes: Accipitridae). Oocysts of Caryosp ora aquilae n. sp. found in faeces of the gold eagle Aquila chrysaetos are subspherical to broad ellipsoidal and measure 43 (40-49) x 37.5 (34-39) mu m. Polar granule, oocyst residuum and micropyle are absent. Each oocyst con tains one spherical to subspherical slightly polygonal sporocyst measuring 23.8 (23-25) x 23.3 (22-25) mu m. Stieda and substieda bodies are absent. T he sporocyst residuum is composed of numerous small granules less than 0.5 mu m in diameter dispersed randomly among the sporozoites. Sporulated oocys ts of Caryospora circi n. sp. from faeces of the marsh harrier Circus aerug inosus are widely oval, measuring 24.5 (23-25) x 21.8 (21-24) mu m. A polar granule, oocyst residuum and micropyle are absent. Each oocyst contains on e spherical to subspherical sporocyst measuring 16.2 (15-17) x 15.6 (15-17) mu m. A compact granular, spherical to subspherical sporocyst residuum, 10 .4 (10-11) x 8.5 (7-9), was present in 76% of measured sporocysts. In 24% o f sporocysts the granules of sporocyst residuum were scattered among the sp orozoites.
