Monomorphic, monokaryotic throughout life cycle; development described in xenomas; hypertrophic cells containing parasites are not xenomas in the sense applied to Glugea cysts; host cells have a simple plasma membrane and enlarge in response to parasite multiplication to become bags of spores; type species A. portucalensis Azevedo, 1987 in hepatopancreas of Carcinus maenas (Crustacea, Decapoda).
