schizogastry

The key demonstrates the impossibility of the system: it starts with errors and it continues with the use of characters that are not comprehended (the superfamily Palaeacaroidea is said to be the only group in which the gnathosoma is visible from above, although this character is present in the Par¬ hypochthoniidae and in some Enarthronota too; the diagastry of the Nanhermanniidae, the pseudodiagastry of the Eulohmanniidae, and the schizogastry of the Epilohmanniidae are used as one character; etc.).

The conditions of ventral sclerotization extend from the primitive condition of agastry in the Palaeacaroidea, to diagastry in the Nanhermanniidae, pseudodiagastry in Eolohmannidae, schiogastry in the Epilohmanniidae, and varied conditions of eugastry in the higher oribatids.

The separation of the genito-aggential region from the ano-adanal region by a transverse scissure in the Epilohmanniidae is termed schizogastry.
