Adeleorina is a suborder of Apicomplexa.
Léger proposed this taxon in 1911. The first species identified was Dactylosoma ranarum by Lankester (1871) in a frog in Europe. It was initially called Undulina ranarum, but this was changed in 1882 to Drepanidium ranarum. This species was subsequently moved to the genus Dactylosoma.
Canine hepatozoonosis was first described in India in 1905 by James. The organism was named Leukocytozoon canis. The vector was identified in 1907 by Christopher to be the brown dog tick (Rhipicephalus sanguineus). The genus Hepatozoon was created by Miller in 1908 for a parasite of the white rat (Rattus norvegicus) that underwent merogony in the liver and sporogony in the mite Laelap echidinus. Ledger initially placed this genus in the family Haemogregarinidae, but Wenyon subsequently removed it and placed it in the newly created taxon Hepatozoidae in 1926.
All species in this suborder use the syzygy method of gamete formation. This involves the association of often motile gamonts prior to the formation of functional gametes and fertilization.
