Genera |
 | | Mature trophozoites fixed to stomach epithelium by a differentiation from the protomerite; this protoepimerite is dilated into a sucker and forms lobes which adhere closely to the microvillosities of the stomach epithelium; association precocious, composed of a primite and one or two satellites, these last being placed side by side; in amphipod and decapod crustaceans. |
 | | Epimerite subglobose with lateral, recurved hooks; oocysts prismatic, composed of a central, regular hexagonal prism capped at each end by a rectangular, truncated hexagonal pyramid; spines long, in two series of 6 each, inserted symmetrically in the tetrahedral angles at the junctions of the apical pyramids with the central prism; in dragonfly naiads. |
 | | Epimerite broadly ovoid, truncated posteriad, with broad, flexible equatorial tumidi that do not form hooks, spines, or digitiform processes; borne on a long, slender stalk; oocysts dodecahedral, elongate, terminally truncate, hexagonal in equatorial cross section, without equatorial faces, with equatorial and terminal spines. |
