Paratrophurus is close to Tylenchorhynchus but differs mainly in the abnormally thickened terminal cuticle of the tail. Both genera have similar face view (SEM) with labial disc and labial sectors fused into a quadrangular strucutre. In Paratrophurus the basal bulb of the esophagus is offset from the esophago-intestinal axis, tha spicules are flanged and the gubernaculum is protrusible (Castillo et al., 1989).
