Dictyoptera (from "Greek δίκτυον diktyon "net" and πτερόν pteron "wing") is an insect "superorder that includes two extant "orders of polyneopterous insects: the order "Blattodea ("termites and "cockroaches together)[1]) and the order "Mantodea (mantises), along with one extinct order, the "Alienoptera. While all modern Dictyoptera have short "ovipositors, the oldest fossils of Dictyoptera have long ovipositors, much like members of the "Orthoptera.

Classification and phylogeny[edit]

The use of the term Dictyoptera has changed over the years, and while largely out of use for much of the last century, it is becoming more widely used. It has usually been considered a superorder, with Isoptera, Blattodea and Mantodea being its three orders. In some classifications, however, Dictyoptera is shifted to order status and in others the class Isoptera has been subsumed under Blattodea while retaining Dictyoptera as a superorder. Regardless, in all classifications the constituent groups are the same, just treated at different rank. Termites and cockroaches are very closely related, with ecological and molecular data pointing to a relationship with the cockroach genus "Cryptocercus.[2][3]

Based on genetic evidence, the closest living relatives of the Dictyoptera are the "phasmids and the enigmatic groups "Mantophasmatodea and "Grylloblattodea. If the Dictyoptera are considered a superorder these three orders might be included in it.[4]

Evolutionary relationships based on Eggleton, Beccaloni & Inward (2007), are shown in the "cladogram:[5] The cockroach families "Lamproblattidae and "Tryonicidae are not shown but are placed within the superfamily Blattoidea. The cockroach families "Corydiidae and "Ectobiidae were previously known as the Polyphagidae and Blattellidae.[6]
