Present and future of the knowledge about the genus Eumerus Meigen, 1822 (Diptera: Syrphidae) in the Iberian Peninsula

Abstract

The genus Eumerus Meigen, 1822 (Diptera: Syrphidae) is one of the most diverse hoverfly genera in the west Palaearctic Region with 140 confirmed species and 80 occurring in the European continent. It is also highly diverse in the Iberian Peninsula plus the Balearic and Canary Islands with 43 species. Recent works on this genus have increased the number of species endemic to the Iberian Peninsula up to five. Nowadays, taxonomy, distribution and biology of the Iberian Eumerus taxonomy are still far to be fully understood. The aim of this work is to present an updated overview of the Eumerus taxonomy and diversity in the Iberian area, addressing main topics pending of resolution in the genus.
