Etymology - name derived from the Greek, diphthera (a membrane) and phero (to bear).  Refers to the loose or swollen cuticle seen in the superfamily Diphtherophoroidea

The Diphtherophoroidea were separated from the Dorylaimida (Class Enoplea, subclass Dorylaimia) and transferred tothe Triplonchida (Class Enoplia, subclass Enoplia) by Coomans and Loof (1986) based on the male spicules being enclosed in a spicular pouch of (presumably) muscle tissue rather than being controlled by spicule protractor muscles.  That classification is retained currently (Zullini, 2006)

Morphology and Anatomy:

Two-part esophagus, slender anteriorly, swollen muscular and glandular posteriorly. Complex onchiostyle usually not hollow, often grooved.
