Early stage of evolution of Gonomyia (Diptera: Limoniidae), new significant discoveries in the Cretaceous Iberian and Kachin amber

Abstract

AbstractThanks to detailed studies of inclusions in Spanish and Kachin amber, it was also possible to study the morphology of insects belonging to the genus Gonomyia. A new material under investigation made it possible to establish two new nominative for science subgenera within the genus Gonomyia has been designated with unique set of characters of antenna, wing venation and genitalia. Two new species within two new subgenera have been described and documented by drawings and photographs, there are Gonomyia (Iberiana) penalveri subgen. et sp. nov. and Gonomyia (Cretagonomyia) burmitica subgen. et sp. nov. The new discovery is the first record of the genus Gonomyia (Diptera: Limoniidae) in Cretaceous Spanish amber and the second in Kachin amber. The new discovery adds to the knowledge of the crane fies’ diversity and evolution, especially its first stage in the Cretaceous.
