This contribution describes new fossil insect taxa from the upper section of the Potrerillos Formation at “Quebrada del Durazno” (South of Cerro Cacheuta), Mendoza Province, Argentina. The age of the insect assemblage corresponds to the early Late Triassic. The following new genus and species are proposed: Argentinosyne duraznoensis Martins-Neto & Gallego sp. nov. (Schizocoleidae Rohdendorf), and Cacheutacicada kurtzae Martins-Neto & Gallego gen. nov., sp. nov. (Hemiptera, Cicadomorpha). Also, Notopamphagopsis? sp. 1, previously described from the Los Rastros Formation (del Bermejo basin, La Rioja, Argentina), is reported. These insect records increase the knowledge of Triassic biodiversity and the relationships with other Gondwanan faunas, contributing new evidence for the insect recovery after the end-Permian extinction and their evolution in west Gondwana.Argentinosyne duraznoensis Martins-Neto & Gallego sp. nov.
