Orthopterida
The Orthopterida is a superorder of the Polyneoptera that represents the extant orders Orthoptera, and Phasmatodea. The Orthopterida also includes the extinct orders Titanoptera and Caloneurodea.
There is general consensus of monophyly in this superorder, based on reduction of the second valvulae, an ovipositor derived from the gonoplac, and an enlarged precostal region on the forewing.
The two other superorders of the Polyneoptera are the:
- Plecopterida, which represents the orders:
- *Plecoptera
- *Emboidea
- *Zoraptera.
- Dictyoptera, which represents:
- *Blattodea
- *Mantodea.
Two other orders, the Notoptera and Dermaptera are also placed in the Polyneoptera but outside the superorders discussed above.
