Host: Umbra krameri. - Locality: swamps in Kiskunság National Park. - Location: gut epithelium, faeces. - Host/Infection: 15/8. Remarks: This species resembles E. laureleus Molnár et Fernando, 1974 but differs in having compact residuum in the sporocyst. Fig. 1: Eimeria kassaii sp. n. The species is named after Dr. Tibor KASSAI, parasitologist, Helminthological Laboratory, University of Veterinary Scien.ee, Budapest. Eimeria matskasii sp. n. (Fig.

2) Diagnosis. - Oocyst spherical, 11.0 (10.5-11.5) in diameter. Cyst wall smooth, colorless, composed of a single, very thin layer (~0.1). Sporocysts compact, in contact with the oocyst wall. Oocyst residuum and micropyle absent, one or two polar granules present, 1.7 (1.5-1.9) in diameter. Sporocyst oval, measuring 8. 8 (8. 5-9. 1) x 4. 0 (3.5-4.5). Stieda body 1.0 (0. 9- 1, l).long with a thickening and 4 papillae situated on the tapered end of the sporocyst. Sporocyst wall 0. 1 thick, with a pattern of 18-20 concentrical stripes. Sporocysts are usually arranged so that two parallel sporocysts cross each other. Each sporocyst with 2 vermiform sporozoites arranged head to tail; one end of each reflexed. Measurements of sporozoites without reflexed portion 8. 1 (7. 7-8. 5) x 1. 5 (1. 4-1. 7). Each sporozoite possesses an ellipsoidal refractile globule, measuring 2x1. Sporocyst residuum dispersed, composed of 3-5 coarse granules. In younger oocyst, however, it is round and compact, 1.3 (1.0-1. 5) in diameter. Sporulation of the oocysts was completed in the gut of the host.
