An Updated Overview of the Genus Eumerus Meigen, 1822 (Diptera: Syrphidae) in the Iberian Peninsula

The genus Eumerus Meigen, 1822 (Eristalinae: Merodontini) is one of the most diverse hoverfly genera in the west Palaeartic Region with 89 confirmed species and 77 occurring in the European continent. It is also highly diverse in the Iberian Peninsula plus Balearic Islands with 36 species. Recent descriptions of four new species have increased the number of species endemic to the Iberian Peninsula up to five. Nowadays, taxonomy, distribution and biology of the Iberian Eumerus are still far to be fully understood. The aim of this work is to present an updated overview of the Eumerus checklist in the Iberian area, addressing main topics pending of resolution in the genus.
