Cheilosia longicornis Michl, 1911 Notes. Reported from: Austria. In the original description of C. longicornis, Michl stated that the distribution area of the species is unknown. On the voucher specimen only “old collection” is noted (Michl 1911: 291). This record was later transmitted by Franz (1989). The voucher specimen is kept in the Natural History Museum Wien and was re-examined by Claus Claussen some years ago. He found out that the specimen belongs to the genus Hiatomyia Shannon, 1922. Omitted because, to date, Hiatomyia is so far only known from North America.
