Descrição de novo táxon fóssil de Cicadoidea: uma contribuição para a paleontomofauna da Formação Fonseca

Abstract

This paper presents what may be a new species of the genus Fonsecacicada (Auchenorrhyncha Cicadidae), being the second fossil record for the Southern Hemisphere, launching a new approach to how the group may have migrated from Australia to Brazil in the Eocene-Oligocene period. The specimen was collected in the Fonseca Formation of the State of Minas Gerais. The Fonseca Formation, Fonseca Basin, Oligocene age, is recognized for its quality of preservation of fossil materials, including, for example, fish, invertebrates and plants; these specimens are of invaluable importance as they record evidence of paleoecology and the groups present in the paleontomofauna of the Fonseca Formation.
