Xylota caeruleiventris Zetterstedt, 1838

Notes. Reported from: Styria (ST), Lower Austria (NÖ) and Vorarlberg (VB). Waitzbauer (2001) published several records for Styria and Lower Austria (Wildnisgebiet Dürrenstein). Mörtelmaier (1999) and Aistleitner (2008) published records of X. coeruleiventris Zetterstedt, 1838 for Styria and Vorarlberg. There was a lot of confusion about these species in the past. X ylota jakutorum Bagatshanova, 1980 was frequently referred to as X. coeruleiventris (auct.) (= an incorrect spelling of the name X. caeruleiventris ; see Speight 2020). Furthermore, dark specimens of X. jakutorum can be easily misidentified as X. caeruleiventris . Therefore, careful examination is needed (Doczkal 2004). Voucher specimens should be checked before the species can be added to the list. We consider it as very likely that this species occurs in Austria, as it is reported from the neighbouring countries Czech Republic, Germany and Slovenia ( Speight 2020).
