Abstract

Lara, M.B., Bashkuev, A. & Wang, B., 1.10.2014. Argentinopanorpa miguezi gen. et sp. nov.: first record of Triassic Mecoptera (Permochoristidae) from the Cuyo Basin (Mendoza, Argentina). Alcheringa 39, 000‒000. ISSN 0311 5518A new genus and species of Permochoristidae, Argentinopanorpa miguezi, is described based on a complete forewing from the Upper Triassic Potrerillos Formation (Mendoza Province, Argentina). The new taxon is placed in the subfamily Agetopanorpinae and distinguished from other genera by the following combination of characters: Rs+MA with six branches, MP with eight branches (MP1 and MP3 with additional forks), CuA and MP fused basally for a short distance. This is the first record of Permochoristidae in the Triassic of South America and the first formal description of Mecoptera from the Cuyo Basin. Previously reported taxa attributed to Mecoptera from the Triassic of South America are briefly discussed with notes on their systematic position.María Belén Lara (corresponding author)[lara.maria.belen@live.com.ar], Area Entomología (Facultad de Ciencias Exactas y Naturales y Agrimensura-Universidad Nacional del Nordeste) and Area Paleontología (Centro de Ecología Aplicada del Litoral-Consejo Nacional de Investigaciones Científicas y Técnicas-Universidad Nacional del Nordeste), Casilla de Correo 128, 3400 Corrientes, Argentina; Alexei Bashkuev [fossilmec@gmail.com], Paleontological Institute, Russian Academy of Sciences, Profsoyuznaya ul. 123, Moscow, 117997 Russia; Bo Wang [savantwang@gmail.com], Steinmann Institute, University of Bonn, 53115 Bonn, Germany and State Key Laboratory of Palaeobiology and Stratigraphy; Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008, PR China.
