The family was erected by Andrassy (1984) 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 elationship between the stoma of Tylopharynx and the stylet of the Tylenchida.
Later, De Ley et al (1994) described the the unusual genus Aenigmenchus from the Galapagos Islands and added it to the family.
