Chrysotoxum octomaculatum Curtis, 1837

Notes. Reported from: Styria (ST), Upper Austria (OÖ), Lower Austria (NÖ) and Burgenland (BU). Records published by Franz (1989), Morge (1974) and Metz (2012) are considered as dubious. Voucher specimens must be reexamined before the species can be added to the list. We consider it very likely that this species occurs in Austria, as it is reported from Central through southern Europe (Speight 2020).
