Belongs within: Sporozoa.
Contains: Eimeria.

The Eimeriorina are a group of intracellular parasites in which macro- and microgametes are produced independently (Adl et al. 2019).

Characters (from Adl et al. 2019): Microgametes and macrogametes develop independently; syzygy is absent; microgamonts produce large number of cilated microgametes; zygote is nonmotile; sporozoites always enclosed in sporocyst within oocyst.
