Bombus (Pyrobombus) haematurus
The range of the species is of the Pontic type, but its habitat is restricted to the rainy forest zones. It is found in Albania, E. Yugoslavia, Macedonia, Romania, Bulgaria, Greece, Turkey, the Caucasus, Armenia, Azerbaydzhan and N. Iran. It is mostly encountered in Bulgaria and N. Turkey, but common nowhere. It reaches the extreme south-east of the West-Palaearctic region in the Kopet-dag, at the border between Iran and Turkestan. It recently extended its distribution toward the west, reaching now Croatia, Slovenia, Slovakia and Austria (Jenic et al. 2010).
