摘要
本文报道了一种新的鳞翅目昆虫（半翅目：Cicadomorpha），Duraznoscytinum aristovi gen.et sp.nov。该标本是从阿根廷门多萨Cuyana盆地Cerro Cacheuta以南的Quebrada del Durazno地区的Potrerillos组（上三叠纪）上段发现的。这代表了南美洲三叠纪第一次记录到镰刀蝶类完整的前翅（被盖+喙）。此外，我们还简要讨论了三叠纪镰刀蝶目在世界范围内的分布，并提供了在南半球记录的分类群之间观察到的初步形态差异。本文描述的新化石有助于了解中生代早期Cerro Cacheuta地区南部存在的半翼生物多样性。
Duraznoscytinum aristovi gen. et sp. nov., a new scytinopterid (Hemiptera: Cicadomorpha) from the Upper Triassic of Argentina
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.
