* Subclass [[Gregarinasina]] (the gregarines)
* Subclass [[Coccidiasina]]
** Suborder [[Adeleorina]] (the adeleorins)
** Suborder [[Eimeriorina]] (the eimeriorins)
* Subclass [[Haemosporidiasina]]
** Order [[Achromatorida]]
** Order [[Chromatorida]]

The division into Achromatorida and Chromatorida, although proposed on morphological grounds, may have a biological basis, as the ability to store [[haemozoin]] appears to have evolved only once.<ref name=Martinsen2008>{{cite journal |vauthors=Martinsen ES, Perkins SL, Schall JJ |title=A three-genome phylogeny of malaria parasites (Plasmodium and closely related genera): evolution of life-history traits and host switches |journal=Mol.
