Morphology and Anatomy:

Neodiplogastridae is distinguished from Diplogastridae in the asymmetric versus symmetric metastom and the movable teeth versus fixed teeth.

Two subfamilies: Neodiplogastrinae Paramonov, 1952  and Mononchoidinae Andrassy, 1976.

Mononchoidinae: Stegostom in left subventral position always with a serrate plate.

Neodiplogastrinae: Stegostom in left subventral position with one or two denticles, or without any armament.

In some genera the stoma comes in two forms, a longer, narrower form with less armamentation (stenostomous form) and a shorter, wider, more heavily armed form (eusrystomous form), eg., in Pristionchus.  Prevalence of the two forms may relate to food availability and whether the species is in predatory or becterivore mode.
