Morphological features of gametocytes, which are used for identification of Haemoproteus species parasitizing Cuculiformes birds. Macrogametocytes (a–f) of Haemoproteus cuculis (a), H. centropi (b–e) and H. clamatori (f). Note that pigment granules in H. centropi gametocytes tend to aggregate into compact large masses (c) or loosely aggregated clumps (e). Long simple arrows—host cell nuclei. Short simple arrows—parasite nuclei. Simple arrowheads—pigment granules. Other explanations are given in the text
