Fig. 101. Map of the distribution of all samples examined for B. sibiricus (Fabricius, 1781) s. lat., showing the distributions of the red-tailed taxon (colour pattern) sibiricus s. str. (orange spots) and the black-tailed taxon (colour pattern) flaviventris Friese, 1905 (blue spots) on either side of the Mongolian deserts (data from the collections of the AB, EA, EB, IAR 2006‒2012, IZCAS, LMOB, NHMUK, PW, RJ, UUH, and VLA, all non-Russian specimens identified or checked by PW, together with Russian records identified by AB). The southern border of Mongolia runs through the middle of the desert region where no bumblebees have been found. The yellow area is classified as desert.
