    Morphology and Anatomy:

    Although Neodiplogaster is thought to be closely related to Tylopharynx, however molecular phylogenies of Diplogastridae suggest that Neodiplogaster is sister to Mononchoides while Tylopharynx is in a sister clade with Paroigolaimella, Sachsia and Eudiplogasterium (Susoy et al., 2015).

    Like Pristionchus, there is dimorphism in the stoma morphology of Neodiplogaster. Ther predatory eurystomatous wider stoma form predominates when the nematodes are in the predatory mode and the stenostomatous narrow form when they have access to bacteria. (Susoy et al., 2015)..

    Feeding:

    Neodiplogaster appears to ne a specialiszd fungal feeder (Kanzaki et al. 2008). It resembles Tylopharynx (Diplogastridae) in having stomatal armature reminiscent of the tylenchid stylet

    Both Neodiplogaster and Tylopharynx can feed on fungal hyphae by tearing apart their cell walls and sucking out the content (Kanzaki 2016).

    The narrow and elongated stegostom cylinder extending to the periradial struts that possess a subdorsal apodeme is similar to the stylet in tylenchids. Based on this synapomorphic trait, Neodiplogaster is thought to be closely related to Tylopharynx (Slos et al., 2018).
