All species in this clade are homoxenous or facultatively homoxenous. Merogony, gamogony and oocyst formation all occur within the same host. The hosts may be vertebrates or invertebrates.

Erroneous identifications of species is a major problem in coccidian systematics and it is likely that some of the genera and species will be revised.

Taxonomy

There are 12 families, 2 subfamilies and 50 genera recognised in this suborder.

The genus Eimeria with ~1500 species is the largest genus in this suborder.

Notes

One genus is entirely entomoxenous (parasitic on insects) — Barrouxia.

The taxonomic status of Atoxoplasma remains unclear.
