Heimburg, Helge, Doczkal, Dieter & Holzinger, Werner E., 2022, A checklist of the hoverflies (Diptera: Syrphidae) of Austria, Zootaxa 5115 (2), pp. 151-209 : 171

Merodon aeneus (Megerle in Meigen, 1822) & Merodon cinereus (Fabricius, 1794)

Aistleitner et al. (2020) include these species under the name “ Merodon aeneus agg.” and “ M. cinereus agg.”; but without further comments. However, we have confirmed the presence of Merodon cinereus (Fabricius, 1794) and Merodon aureus Fabricius, 1805 from Vorarlberg (Ante Vujić pers. comm.). Both species are in the species group Merodon aureus sensu Radenković ( Šašić et al. 2016). Further information about Merodon aureus (ex M. aeneus ) can be found in Vujić et al. (2020b). To avoid confusion, we have not included these species names given by Aistleinter et al. in our present checklist. Most recently M. cinereus was reported by Schlüsslmayr (2021) from Upper Austria.
