Abstract: The discussed species: Syrphoctonus flavolineatus (Grav.), S. holarcticus, nov.
spec., S. biguttatus (Grav.) and S. abdominator (Bridg.) are very difficult to
distinguish. An attempt was made to work out characteristics that permit an easy
separation of the species. Syrphoctonus holarcticus has been newly described.
