Genus Gerarus Scudder, 1885 , Osnogerarus Kukalová­Peck & Brauckmann, 1992 . The genera Omalia van Beneden & Coemans, 1867 , Cantabrala Kukalová­Peck & Brauckmann, 1992 , Genentomum Scudder, 1885 , Nacekomia Richardson, 1956 . Gerarulus Handlirsch, 1911 have uncertain relationships within Archaeorthoptera. Anepitedius Handlirsch, 1911 , Axiologus Handlirsch, 1906 , Platyphlebopteron Germer, 1971 and Progenentomum Handlirsch, 1906 are here considered as a ‘Protorthoptera’ incertae sedis . Discussion. After the present phylogenetic analysis, Gerarus bruesi would fall into the Orthoptera . Nevertheless, the Geraridae are provisionally considered of uncertain position within the Panorthoptera.
