The order Zoraptera is one of the most enigmatic insect groups. Its phylogenetic position is far from settled, and more than ten different placements have been discussed since the insects were first discovered. This problem is also difficult to resolve with molecular studies because of the unusual characteristics of zorapteran 18S rDNA sequences, which are the most widely used genetic markers for the estimation of the deep phylogeny of insects. In this study, the wing base structures of Zoraptera and various potential sister taxa were examined. Numbers of unique modifications were detected in the wing base structure of Zoraptera, and six were also observed in the wing base of Embiodea (Embioptera, Embiidina; webspinners). No possible synapomorphies supporting the other relationships were detected. This is the second unambiguous morphological synapomorphy providing strong evidence for the phylogenetic position of Zoraptera.
