Abstract
Choleoeimeria duszynskii n. sp. is described from the gallbladder of the Middle Eastern short-fingered gecko Stenodactylus doriae (Blanford) from Salasel, Central region, Saudi Arabia. Oöcysts are ellipsoidal (rarely ovoidal), 23-25×16-18 (24×17)μm, with mean length/width ratio 1.4. Oöcyst wall is smooth, bi-layered, c.1.0μm thick. Micropyle, oöcyst residuum and polar granule are absent. Sporocysts are ellipsoidal, 8-10×4-6 (9×5)μm, with a smooth, colourless sporocyst wall and mean length/width ratio 1.7. Sporozoites are sausage-shaped, with one end slightly pointed, arranged head to tail around sporocyst residuum. Refractile bodies and nuclei are not discernible. The endogenous development is restricted to the epithelium of the gallbladder and bile duct. Meronts are rounded, 12μm in diameter, containing up to c.15 merozoites. Microgamonts are irregular in shape, 22×17μm, containing a large number of microgametes. Macrogamonts are spherical, 17μm in diameter, with centrally located nucleus and wall-forming bodies at the periphery.
