Based on observations of variability in the postembryonic development of the caudal region of Dorylaimida, and on molecular analysis, Pena-Santiago and Alvarez-Ortega (2014) proposed that the family Qudsianematidae be assigned as a subfamily of the Dorylaimidae emended the diagnosis of the subfamily Qudsianematinae as follows:
