摘要

New species of eimeriid coccidia (Apicomplexa: Eimeriidae) is described from the Common Wood Pigeon Columba palumbus (Aves: Columbidae). Sporulated oocysts of Eimeria columbapalumbi sp. n. are ellipsoidal 24-17 × 18-15 μm. Micropyle and oocyst residuum are absent. Sporocysts are broadly ellipsoidal, 11-16 × 6-7 μm, with Stieda body. ubstiedal body is absent. Sporocyst residuum is scattered, composed of hundreds of small granules. Sporozoites are elongate and slightly curved, each with two refractile bodies. There are two irregularly shaped polar granules present in the oocyst. The endogenous development takes place within the enterocytes of jejunum.
