Taxonomy

There are eleven families recognised in this suborder. There are ~400 species in these families.
Five families — Allantocystidae, Diplocystidae, Enterocystidae, Ganymedidae and Schaudinnellidae — have only one genus. Aikinetocystidae has two genera.
Two families in this suborder — Ganymedidae and Thiriotiidae — infect crustaceans.
The taxonomy of this suborder may be in need of revision as it has been shown based on SSU 18S rDNA sequences that four families — Ganymedidae from the Aseptatorina and Cephalolobidae, Porosporidae and Uradiophoridae from the Septatorina appear to form a superfamily. The name Cephaloidophoroidea has been proposed for this superfamily
