Eimeria caretta sp.nov. (Apicomplexa: Eimeriidae) is described from the feces of a stranded loggerhead turtle, Caretta caretta (Testudines), rescued from the Atlantic coast near Jensen Beach, Hutchinson Island, Martin County, Florida. Oocysts are subspherical to ellipsoidal, 24.5 × 22.0 (21.4–28.0 ×...

| Summary: | Eimeria caretta sp.nov. (Apicomplexa: Eimeriidae) is described from the feces of a stranded loggerhead turtle, Caretta caretta (Testudines), rescued from the Atlantic coast near Jensen Beach, Hutchinson Island, Martin County, Florida. Oocysts are subspherical to ellipsoidal, 24.5 × 22.0 (21.4–28.0 × 18.4–24.0) μm, with a smooth, bilayered wall. Micropyle, polar granule, and oocyst residuum are absent. Sporocysts are ovoid, 14.3 × 8.9(12.8–16.0 × 8.2–10.0) μm, and possess a Stieda body but no substieda body. The Stieda body is unusual in that 12–20 long, thin filaments project from its surface. Sporozoites are elongate, each with two refractile bodies. The sporocyst residuum consists only of scattered granules. This coccidian is most similar to Eimeria filamentifera Wacha and Christiansen 1979 from the common snapping turtle, Chelydra serpentina, but differs because it possesses more numerous and elongate filaments associated with the Stieda body and lacks an oocyst residuum. |
