In this contribution several new fossil insect taxa of the orders Blattoptera, Miomoptera, Glosselytrodea, Auchenorrhyncha, and Coleoptera are described from the lower section of the Los Rastros Formation at the Los Chañares locality, La Rioja Province, Argentina. The formation is dated as early Late Triassic. A new subfamily, two new genera, and four new species are proposed: Miomina riojana n. sp. (Miomoptera), Chanarelytrina nana n. gen. n. sp. (Glosselytrodea), Chanarescytina carmonae n. gen. n. sp. (Auchenorrhyncha, Scytinopteridae, Saaloscytininae n.  subfam.) and Argentinosyne bonapartei n. sp. (Coleoptera, Permosynidae). Additionally, the previously described species from the upper section of the Los Rastros Formation are now also recorded at the Los Chañares locality: Condorblatta lutzae Martins-Neto & Gallego, in press (Blattoptera, Argentinoblattidae) and Argentinocupes pulcher Martins-Neto & Gallego, in press (Coleoptera, Cupedidae).
