Revision of the fossil ''mantid'' and ''ephemerid'' species described by Piton from the palaeocene of Menat (France) (Mantodea: Chaeteessidae, Mantidae; Ensifera: Tettigonioidea)

Some fossil insects from the Palaeocene of Menat (France), described by Piton as Mantodea, but also Ephemeroptera are revised.
