Abstract: The oocyst is described of Eimeria peltocephali n.sp. from faeces of the freshwater turtle Peltocephalus dumerilianus from Barcelos, State of Amazonas, Brazil. Sporulation is exogenous and fully developed oocysts are elongate, ellipsoidal or cylindrical, frequently curved to a banana-shape, 54.4 ×19.1 (37.5 - 68.7 × 18.7-20.0 μm), shape-index 2.8 (1.8 -3.9). The oocyst wall is a single thin, colourless layer about 1 μm thick, with no micropyle. There is a bulky oocyst residuum, at first spherical to ellipsoidal, 19 × 16 (16. 2 -26.2 × 16 - 21.5μm) , but becoming dispersed on maturation. There are no polar bodies. The sporocysts, 19.1 × 6.8 (17.5 -21.2 × 6.2 -7.5 ×m), shape- index 2.8 (2.3 -3.2), are usually disposed in pairs at each end of the oocyst, and bear an inconspicuous Stieda body in the form of a flat cap. The sporozoites are elongate and slightly curved around the residuum. No refractile bodies were seen. Eimeria molossi n.sp., is described from the molossid bat Molossus ater. Sporulation is exogenous and the mature oocysts are predominantly broadly ellipsoidal, 23.4 × 17.5 (18-30 × 15-22.5 μm), shape-index 1.3 (1-1.6). The oocyst wall is about 2 μm thick, and of three layers: an inner thin, colourless one and two outer layers which are thicker, yellowish-brown, prominently striated and in close apposition. There is no micropyle or oocyst residuum, but one and occasionally two polar bodies are usually present. Sporocysts are ellipsoidal, 10.2 × 7.5 (10-12.5 × 7.5 μm), shape-index 1.4 (1.3-1.7) with an inconspicuous Stieda body. Endogenous stages are described in the epithelial cells of the small intestine.
