Orthonevra plumbago (Loew, 1840)
Notes. Reported from: Styria (ST) and Lower Austria (NĂ–). Records published by Franz (1989) are considered as dubious. Voucher specimens should be re-examined 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 neighbouring countries (e.g., Switzerland, Germany, Hungary) (Speight 2020).
