The insect order Notoptera, a group first proposed in 1915, has been largely unused since its original conception, but in the most recent classification of the lineage of insects that includes the Grylloblattodea and Mantophasmatodea^[1], the name was resurrected and redefined so as to give a single order that includes both the living and fossil representatives of the lineage. As now defined, then, the order comprises four families, two of them known only from fossils, and two known from both fossil and living representatives, and fewer than 30 known species in total.
