Enigmaptera magnifica gen. et sp. nov., type genus and species of the new odonatopteran family Enigmapteridae, is described from the Moscovian of Avion (northern France). It is the sister group of the major clade Neodonatoptera, placed together in the new clade Paneodonatoptera.
Its wing venation has characters never found in other Odonatoptera. It is a further case of convergent wing petiolation in this superorder.
Enigmaptera magnifica, like the protozygopteran Jacquesoudardia magnifica from the same outcrop, probably lived like the extant damselflies along the shores of lakes and rivers, hunting the small insects found in the same deposits. These discoveries show that very small insects were significant elements of the entomofaunal diversity and trophic chains of the Late Carboniferous ecosystems.
