Key to the Haemoproteus species of Pterocliformes birds

Step	Features and speciesa
1 (2)	Nuclei of macrogametocytes are median in position (Fig. 24a)
	………………………………………………………………………………………………………………….	H. krylovi (Fig. 24a) [3]
2 (1)	Nuclei of macrogametocytes are subterminal in positionb
	………………………………………………………………………………………………………………….	H. pteroclis (Fig. 24b) [3, 127]

^aThe original descriptions of the haemoproteids parasitizing Pterocliformes birds were fragmentary and incomplete. Redescription of H. krylovi and H. pteroclis is needed

^bSubterminal position of nuclei in macrogametocytes of H. pteroclis was mentioned in the original parasite description, but it was not illustrated [127]
