The oocysts are characterized by ellipsoidal shape measuring 42.5 x 32.8 µm, with smooth, thick doublelayered wall of a greenish-orange colour. An oocyst residuum of numerousscattered granules among the sporocysts in sporulated ones; 16 round sporocysts, averaging 10.5 x 10 µm each containing four elongated sporozoites; presence of residuum; absence of Stieda body. The presently described coccidian, recorded for the first time in birds, is a new species named P. scleruri.
