Abstract

A new species of Eimeria is described from the faeces of the Blue Rock Pigeon, Columba livia Gmelin, 1789. Sporulation is exogenous and fully developed oocysts are ellipsoidal, 24.3μm x 19.8μm; the shape index (length/width ratio) is 1.2. The oocyst wall is smooth and bilayered. There is no micropyle or oocyst residuum, but a prominent spherical polar granule is present. Sporocysts are pyriform, 12.06μm x 10.1μm; the shape index is 1.2μm. A large and prominent stieda body is present. The sporocyst residuum is present with numerous, nearly uniform granules. Sporozoites are banana-shaped lying lengthwise head to tail inside the sporocyst.
