Abundance; world
Bombus cullumanus has an Atlantic distribution, but is uncommon to very rare throughout its range. Formerly, it was found in the most southern part of Sweden, in Denmark and N.-W Germany, in the Netherlands, in Belgium, in England, in N. France and the Paris region and (with some doubt) in the French Alpes-Maritimes. Nowadays, the last stations where the species has been observed are restricted to the Massif Central and the Pyrenees (including the Spanish side) (Rasmont, 1988). No specimen have been observed since 2004.
