The Metapterygota (Greek meta = after, pterygōtos = winged) are a taxon of insects (Insecta), in which dragonflies (Odonata) and new winged birds (Neoptera) are grouped together. It is mainly used in the cladistic classification of insects.
features
The main feature of the Metapterygota is that the adults no longer molt. They are thus opposed to the mayflies (Ephemeroptera, also called Archipterygota), which, in contrast to the Metapterygota, develop a subimago capable of flying in front of the sexually mature imago . Further features are: reduction of the middle tail filament, the anterior and posterior vascular cords of the trachea in the wings and legs are fused to form an arch and the fixation of the anterior mandibular hinge. In each wing there are branches from two different leg veins; one branch starts from the intersegmental stigma (breathing hole) in front of the wing, the other branch from the intersegmental stigma behind the wing.
Systematics
The taxon was proposed by Carl Julius Bernhard Börner in 1909 . Together with the mayflies (Ephemeroptera), also called Archipterygota by Carl Börner, it forms the group of flying insects (Pterygota). Within the Metapterygota, the dragonflies and the new winged in turn form a sister group relationship. Simplified cladogram:
