IMPORTANT DATA SOURCES FOR THE NOMINAL SUBSPECIES (IN RUSSIA) ARE STILL MISSING ON THIS MAP (24.XII.2010).
The distribution of Bombus sichelii is discontinuous. The northern limit of its range is that of a taiga species. Its most western observations are in the regions of Arkhangelsk and Ivanovo ; it does not reach St Petersburg. Eastwards, the species extends to the Anadyr and Kamchatka peninsulas.
The southern part of its distribution includes various subspecies, isolated on high mountains : B. sichelii flavissimus in the Pyrenees and the western Alps, B sichelii alticola in the central and eastern Alps, B. sichelii drenowskii and dinibengis in the Balkan, B. sichelii cazurroi in N.-E. Anatolia and caucasus. Bombus sichelii has never been observed in the N. European mountains, nor in Fennoscandia.
