Fig. 4 in Unexpected absence of exo-erythrocytic merogony during high gametocytaemia in two species of Haemoproteus (Haemosporida: Haemoproteidae), including description of Haemoproteus angustus n. sp. (lineage hCWT7) and a report of previously unknown residual bodies during in vitro gametogenesis

Fig. 4. Comparison of fully grown gametocytes of Haemoproteus angustus n. sp. (lineage hCWT7) from the blood of Curruca communis (A, B), Haemoproteus sittae (unknown lineage) from the blood of Sittae europaea (C, D) and Haemoproteus dolniki (unknown lineage) from the blood of Fringilla coelebs (E, F). Note: the elongate and markedly attenuated nuclei of infected erythrocytes containing advanced gametocytes of the new species (A, B), which is not the case in other Haemoproteus parasites (C–F). All images are from type specimens of these species. Symbols are the same as in Fig. 2. Giemsa-stained thin blood films. Scale bar = 10 µm.
