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, various structures of larval maxilla and labium, and basal fusion of CuP and A1 veins in hind wings.[1][2] The monophyly of the Panorpida is also supported by molecular data.[3]
