The Superorder Plecopterida is further organized into finer groupings including:
Plecoptera are an order of insects, commonly known as stoneflies. There are some 3,500 described species worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. The modern diversity however apparently is of Mesozoic origin. [more]
The Protorthoptera are an extinct order of Palaeozoic insects, and represent a wastebasket taxon and paraphyletic assemblage of basal neoptera. They appear during the Middle Carboniferous (late Serpukhovian or early Bashkirian), making them among the earliest known winged insects in the fossil record. may be expanded to form a shield. The group includes the ancestors of all other polyneopterous insects. [more]
The insect order Zoraptera contains a single family, the Zorotypidae, which in turn contains one extant genus with 34 species, Zorotypus as well as 9 extinct species. [more]
At least 33 species and subspecies belong to the Order Zoraptera.
