Panorpida or Mecopterida is a proposed superorder of Endopterygota. The conjectured monophyly of the Panorpida is based on morphological, not genomic evidence, namely the reduction or loss of the ovipositor and several internal characteristics, including a muscle connecting a pleura and first axillary sclerite at the base of the wing. The monophyly of the Panorpida is also supported by molecular data.[1]
