I would never subscribe "Altay" for this locality, being lost in a vast perfect steppen plain having nothing in common with the well-known Altai Mts. In fact, this is in the large Russian province called Altaiskiy Kray, almost at its western border with Kazakhstan. The fly (the only specimen) was collected in Klyuchi village at the bank of a shallow brackish lake with some reed thickets at banks. The holotype was collected an year ago within the city of Omsk, that is quite a remote place, but in exactly the same conditions.
