Eimeria muraiae sp. n. (Figs. 4A, B) Diagnosis. - Oocyst ellipsoid or oval, 46.5 (45.5-47) long and 36. 4 (35.8-37.1) wide. Cyst wall smooth, colorless, composed of a single thin layer (0.1-0.2). Sporocysts localize near the centre of the oocyst, with a relatively large space separating them from the cyst wall.'Oocyst residuum, micropyle and polar granule absent. Sporocysts elongated ellipsoidal, measuring 23.4 (22. 1-24. 8) x 9. 0 (8.4-9.5). Sporocyst wall 0.2 thick. Each sporocyst with two banane-shaped sporozoites arranged head to tail. The sporozoites have a refracting area at the tapered end and a longitudinal radiating pattern at the blunt end. Sporozoites measure 17. 6 (17.2 - 18. 1) x 5. 3 (5. 1- 5. 5). Sporocyst residuum finely granulated; compact, ellipsoidal, 10. 2 (9. 5-10. 7) x 6. 5 (6. 2-6. 7) in size and situated at one end in young oocysts, while dispersed throughout the space within the sporocysts in older ones. Host: Misgurnus fossilis. - Locality: swamps in Kiskunság National Park. - Location in the host: kidney, renal tubes. - Host/Infection ratio: 4/2. Remarks: Eimeria muraiae differs from all known Eimeria parasites of fresh water fish by the large size and loose construction of the oocysts. This species is named after Dr. Éva MURAI, parasitologist, Hungarian Natural History Museum, Budapest. Fig. 5: Eimeria nemethi sp. n.
