摘要

This contribution describes new fossil insect taxa from the early Late Triassic Potrerillos Formation (lower section), at qucbrada del puente, Cerro Bayo, Mendoza Province, Argentina. A new family, three new genera, and four new species of Blattoptera are described: Aiwhlatta compacta gen. et sp. new., Potrerilloblatta stipanicici gen. el sp. nov. (Subioblattidae Schneider), Delpuentcblatta dangeloi gen. et sp. nov. and Lariojablalla neiffi sp. nov. (Delpuenteblattidae fani. nov.); and a new coleopteran species, Delpxwntesyne menemlezi sp. nov. (Permosynidac Tillynrd). These findings extend the stratigraphic distribution of the typical Triassic coleopteran taxa. The new assemblage shares the genus Lariojablalla with the Los Rastros fauna. The Blattoptera and Coleoptera genera differ from those typical of the Australian and South African Triassic biota (Ademosyne for Coleoptera and Triassobhuta and Sanuiroblailu for Blattoptera) and appear to be endemic to Argentina (Delpuentesyne, Potrerillobhttia and Di'lpiienteblatla).
