Abstract: Thirty-four out of 142 (23.9%) eared doves, Zenaida auriculata Des Murs, 1847 had oocysts of an Eimeria species described here as a new species. Sporulation is exogenous and fully developed oocysts are spheroid to subspheroid, 23.8 mum (22.1-26.4) x 20.3 mum (19.2-22.1); the shape index (length/width ratio) is 1.2. The oocyst wall is bilayered, with a slightly pitted outer layer and a brown inner layer. There is no micropyle or oocyst residuum, but a prominent elongated polar granule is present. Sporocysts are elongated, 13.1 mum (12.0-14.4) x 7.4 mum (7.2-7.7); the shape index is 1.8 mum with a smooth, thin wall. A large Stieda body is present, but there is no sub-Stieda body. The sporocyst residuum consists of numerous, nearly uniform granules scattered randomly. Sporozoites are elongate with a large, clear refractile body in the posterior end and a smaller refractile body in the anterior region.
