Zygokaratawia reni, a new campterophlebiid genus and species is described from the Middle Jurassic of China. This fossil has a wing shape unique for this clade, i.e. a fore- and hind wing of the same width and very shortly petiolated, and hind wing cubito-anal area nearly as narrow as that of the forewing. This wing shape is convergently similar to that of recent Zygoptera: Calopterygidae, as well as to several other Cenozoic zygopteran clades, suggesting similar styles of flight and habits, i.e. predation on small insects and flight along trees of river banks.
