        Tylopharynx De Man, 1876

 

 Andrassy (1984) erected the family Tylopharyngidae to accomodae the single genus, Tylopharynx. That genus has often been seen as indicative of the origins and relationships of Tylenchida  because of the apparent similarity of its stoma armature to the tylenchid stylet (Andrassy, 1984; Wu et al., 2001). Later studies by De Ley et al. (1993) suggested that there is no strong relationship between the stoma of Tylopharynx and the stylet of the Tylenchida.

Feeding:

Tylopharynx foetida feeds on fungal hyphae by ripping apart the cell wall with stegostomatal teeth. The teeth are pushed out of the buccal cavity by elongation of the pharynx during each pumping cycle (Forst von Lieven, 2002).
