Permothemis libelluloides, fore wing (modified from Jeannel, 1949a)
This is a small order of insects known from fossils from the Permian of North America and Russia. The mesothorax was greatly developed, the fore wing had a well-developed pterostigma and few cross-veins, and the abdomen ended in a pair of long cerci. It has been compared with the Megasecoptera (Protodonata), but was more probably a two-winged development from the Palaeodictyoptera. It has left no recognizable descendants.
