A suborder of coccidia (class Sporozoea) that lack syzygy, with separate development of macrogamete and microgamont, the latter producing eight flagellated microgametes; heteroxenous with merogany in vertebrates and sporogony in bloodsucking insects; includes the genera Haemoproteus, Leucocytozoon, and Plasmodium. [G. haima, blood, + sporos, seed]

Hae·mo·spo·ri·na (he″mo-spor-iґnə) [hemo- + spore] a suborder of heteroxenous protozoa (subclass Coccidia, class Sporozoea) in which merogony takes place in a vertebrate, usually in the blood, and sporogony in the alimentary canal of a blood-sucking insect. Hemosporians are characterized by the independent development of macrogamete and microgamont; the absence of syzygy; the usual absence of a conoid; the production by the microgamont of eight flagellated microgametes; and the formation of a motile zygote (ookinete). Representative genera include Haemoproteus, Hepatocystis, Leucocytozoon, and Plasmodium.
