Dasysyrphus venustus (Meigen, 1822)

The current concept of D. venustus as reflected in identification guides (e.g., Bot & van de Meutter 2019; Speight & Sarthou 2017; Bartsch et al. 2009a) comprises a species complex (Dieter Doczkal, unpublished). Here we adopt the names used by Speight (2020) as taxonomic changes are beyond the scope of the present paper.
