TWO RELATED SPECIES OF PARAGUS (DIPTERA: SYRPHIDAE), ONE FROM THE NEARCTIC AND ONE FROM THE PALAEARCTIC

This paper describes two related species of the subgenus Paragus (Paragus) Latreille 1804 from two remote regions. The study of material from the Bohart Museum (Davis, California, United States) resulted in the discovery of an undescribed Nearctic species, P. vockerothi sp.nov. Simultaneously, one similar new European species, P. glumaci sp.nov., is reported among material collected from the Balkan Peninsula. The description of both species, with figures of male genitalia and diagnostic characters, is given. The zoogeographical significance of the discovery of these species is emphasized.
