Abstract: Eimeria curvata is a new coccidian described in the cloves Columbina talpacoti and Scardafella squammata from western of the State of Sao Paulo, Brazil. The oocysts are ovoid to ellipsoid, 18.3 (17-19) mu m x 15.5 (15-17) mu m, with a shape index of 12.2 (1.1-1.3). The Fi all is colorless, smooth and double-layer cd. A polar granule is present, but there is no micropyle or oocyst residuum. The sporocysts are elongate, 12.3 (11.5-13) mu m x 5.8 (5.5-6) mu m with a curved anterior portion and a smooth, thin, single-layered wall. The Stieda body is protuberant and nipple-like; there is no substieda body. The sporozoites lie head-to-tail in the sporocyst and contain a large refractile body at the extremities. The sporocyst residuum contains small granules uniformly distributed in the middle of the sporocyst. The prevalence of E. curvata n. sp. was 17.4% and 12.8% in C. talpacoti and S. squammata, respectively.
