Diagnostic criteria

The diagnostic criteria of this family are:

  • macrogametes and microgamonts develop independently
  • syzygy absent
  • microgametocyte produces 8 flagellated microgametes
  • zygote is motile (known as an ookinete)
  • conoid present in ookinete stage only
  • sporozoites naked in oocyst (that is without a sporocyst)
  • heteroxenous: merogony and gamogony occur in vertebrate host and fertilization and sporogony in definitive host (a blood sucking insect)
  • hemozoin pigment produced in some genera
