Anew insectfossilfromthe LateCarboniferous lacustrinedeposits ofMontceau-les-Mines is
attributed to a new genus and species, Montceaupterum baillyi of Euryptilonidae (Grylloblattodea).
It is based on forewing venation but it shows also membranous lateral extensions
on the pronotum, maybe corresponding to prothoracic winglets. It represents the oldest
record of the family, previously known only from the Permian.
