Morphological features of fully grown gametocytes, which are used for identification of Haemoproteus species parasitizing Suliformes birds. Macrogametocytes (a, c) and microgametocytes (b, d) of Haemoproteus iwa (a, b) and H. valkiunasi (c, d). Note that the number of pigment granules in fully grown H. iwa macrogametocytes (a) is at least twice that in fully grown microgametocytes (b), but this is not the case in H. valkiunasi (c, d). Long simple arrows—host cell nuclei. Short simple arrows—parasite nuclei. Simple arrowheads—pigment granules. Other explanations are given in the text
