Duraznoscytinum aristovi gen. et sp. nov., a new scytinopterid (Hemiptera: Cicadomorpha) from the Upper Triassic of Argentina

Abstract

A new scytinopterid (Hemiptera: Cicadomorpha), Duraznoscytinum aristovi gen. et sp. nov., is described. The specimen was recovered from the upper section of the Potrerillos Formation (Upper Triassic) at the Quebrada del Durazno locality, south of the Cerro Cacheuta, Cuyana Basin, in Mendoza, Argentina. This represents the first record of a complete forewing (tegminous + clavus) of a scytinopterid for the Triassic of South America. Additionally, we briefly discuss the Triassic scytinopterid distribution worldwide, and provide preliminary morphological differences observed between the taxa recorded in the Southern Hemisphere. The new fossil described herein contributes to the knowledge on the hemipterofauna diversity present at the south of the Cerro Cacheuta area during Early Mesozoic times.
