Reconstruction of Triassophasma, from Gorochov & Rasnitsyn (2002).

Belongs within: Polyneoptera.
Contains: Phasmatodea.

The clade Holophasmatodea includes the modern phasmids and their fossil relatives. Fossils have been assigned to this lineage going back to the Permian or Triassic, though the status of the earliest examples as stem-phasmids has been subject to debate.

Synapomorphies (from Gorochov & Rasnitsyn 2002): Body elongate, stick-like; meso- and metathoraces much longer than prothorax; fore wing with veins subparallel.
