Aseptatorina
''Aseptatorina'' is a suborder of parasitic alveolates of the phylum Apicomplexia 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 crustacean Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp.

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 ...

Eugregarinorida
The ''Eugregarinorida'' are the most large and diverse order of gregarines — parasitic protists belonging to the phylum Apicomplexa. Eugregarines are found in marine, freshwater and terrestrial habitats. These species possess large trophozoites that are significantly different in morphology and behavior from the sporozoites. This taxon contains most of the known gregarine species. These protozoa are common parasites of many invertebrates including insects and polychete worms. Taxonomy Eugregarinorida has three recognised suborders: Aseptatorina, Blastogregarinorina and Septatorina. The intestinal eugregarines are separated into septate — suborder Septatina — and aseptate — suborder Aseptatina — depending on whether the trophozoite is superficially divided by a transverse septum. The marine gregarines are the most poorly studied members of this order. The eugregarines have been classified into 27 families with ~244 genera, 14 of which have more than 25 species each. ...
