Morphological features of gametocytes, which are used for identification of Haemoproteus species parasitizing passeriform birds (suborder Passeri) of the families Meliphagidae, Oriolidae, Pachycephalidae, Vireonidae birds. Macrogametocytes of H. vireonis (a, b), H. ptilotis (c, d), H. pachycephalus (e, f) and H. orioli (g, h). Note that advanced growing gametocytes of H. pachycephalus (size greater than length of erythrocyte nuclei) do not touch the envelope of infected erythrocytes along their entire margin (e, f). Pigment granules are small in gametocytes of H. orioli, and nuclei assume terminal position in macrogametocytes of this parasite (g, h). Images a, c, e are from the type material, which is fading, resulting in pale staining (e) and the poorly recognizable nuclei (a, c, e) and pigment granules (e), however the overall form of the gametocytes is readily visible. Long simple arrows—host cell nuclei. Short simple arrows—parasite nuclei. Simple arrowheads—pigment granules. Simple wide long arrows—space between developing gametocyte and envelope of infected erythrocyte. Other explanations are given in the text
