DESCRIPTION
The parasite lies in a non-deformed, non-hypertrophied RBC whose nucleus is slightly displaced by the larger parasite forms. The young schizonts have 2 to 6 nuclei, and are crescent-shaped and found at the apex of the RBC, generally attached to its edge. Their cytoplasm is abundant, vacuolated and the nuclei though of irregular shape are clearly distinguished individually. As they develop, the schizonts extend along one of the RBC borders, keeping contact with RBC membrane and separated from its nucleus by a band of erythrocytic cytoplasm. Throughout its development, the schizont retains a curved shape, larger on the top of the RBC and narrower along the host nucleus. The number of nuclei is estimated to be around 30, though no fully mature schizonts could be observed.
Gametocytes are elongated and have roughly the same shape and position as the schizonts.
DIFFERENTIAL DIAGNOSIS
The closest species is P.golvani Chavatte & Landau, 2007 , parasite of the magpie.
This parasite is distinguished from the one in the magpie by its general shape which is thinner and more elongated. Moreover, and in contrast to P. reniai n. sp., P. golvani shows a long thin protrusion along the RBC nucleus, its young forms have few nuclei and these are arranged in two rows in the mature forms.
