(Hemiptera: Dysmorphoptilidae), are described from the Upper Triassic of the Potrerillos Formation, at the Quebrada del Durazno locality, south of Cerro Cacheuta, Mendoza Province, Argentina. Additionally, based on new morphological details observed in the supplementary material (CTES-PZ N degrees 7200) provided by Martins Neto et al. (2003), we emend the diagnosis and description of Dysmorphoptiloides acostai Martins-Neto & Gallego, 1999. The new species reported herein not only enrich the fossil record of the hemipteran fauna at the Quebrada del Durazno locality and Upper Triassic Potrerillos Formation, but also suggest that Dysmorphoptiloides was a well-diversified genus in Gondwana during the Middle-Late Triassic.Dysmorphoptiloides sp. nov.Upper TriassicArgentinaGondwanaArticulohttps://doi.org/10.11646/palaeoentomology.9.1.7
