This species is separated from the Chresmodidae (sensu Sharov, 1968) by the branching of the postmedian and anterior median veins. It differs from Aerophasma Martynov in having a weakly-developed cubital vein and in the division of the anterior median vein into two branches. The long parallel-vein appearance is typical of the Xiphopteroidea. The very hairy nature of the wing, particularly clear in the anterior basal part of the wing, is character- istic of the Aerophasmatidae, a family currently known from the Jurassic of the The other families in the Xiphopteroidea are Triassic (Xiphopteridae, Aeroplanidae), Jurassic (Necrophasmatidae) or Cretaceous (Cretophasmatidae). All are regarded as related to, though not necessarily direct ancestors of, modern stick-insects (Phasmidae)..
