A new strange Archaeorthoptera from the Moscovian of Avion (France) (Insecta, Polyneoptera)

A new archaeorthopteran genus and species, Avionugonioneura jouaulti, is described from the Moscovian of the Avion in Northern France. It shows several strong similarities, with the two genera Contracladus (Pennsylvanian) and Nugonioneura (early Permian), viz. a simple vein M emerging anteriorly from M+CuA+CuPa and an anteriorly branched CuA+CuPa, which are putative synapomorphies, suggesting a possible attribution to the family Nugonioneuridae. This discovery confirms the very important diversity of the Archaeorthoptera in the outcrop of Avion.
