Abstract:

The present paper describes new fossil insect taxa from the Los Rastros and Ischichuca Formations, La Rioja Province, Argentina; and from the Santa Juana Formation, Chile. These formations are dated as late Middle Triassic to early Late Triassic. Eight new genera and nine new species are described: Frenguelliphlebia labandeirai n. gen. et n. sp. (Odonatoptera); Argentinoperlidium rogersi n. gen. et n. sp. (Plecoptera: Gripopterigidae); Dysmorphoptiloides pulcherrima n. sp.; Bandelnielsenia chilena n. gen. et n. sp., Gallegomorphoptila breviptera n. gen. et n. sp. (all Auchenorhyncha: Dysmorphoptilidae), Gualoscytina mayae n. gen. et n. sp. (Auchenorrhyncha: Scytinopteridae), Argentinopheloscyta forsterae n. gen. et n. sp. (Auchenorrhyncha: Stenoviciidae); Yurigomicex popovi n. gen. et n. sp., and Popovigocimex yurii n. gen. et n. sp. (both Coleorrhyncha: Progonomicidae). Additionally a checklist of all known described species of South America Triassic is provided (except Blattoptera and Coleoptera, paper in preparation), as well as a discussion of dispersal paths of Triassic conchostracan and insects faunas of Gondwana.
