ABSTRACT. Bumblebee species of the genus Bombus Latreille, 1802, subgenus Megabombus von Dalla Torre, 1880, are re-assessed world-wide with a species-coalescent analysis of COI barcodes. An integrative analysis of this evidence together with morphological characters shows (1) support for the widespread Eurasian species B. consobrinus Dahlbom, 1832 including as synonyms the taxa B. yezoensis Matsumura, 1932, syn.n. (from Japan) and B. przewalskiellus (Skorikov, 1933), syn.n. (from North China); (2) support for B. tichenkoi (Skorikov, 1926) s.l. as a widespread but under-recognised species in Asia that includes as synonyms the taxa B. saltuarius (Skorikov, 1931), syn.n. (from Russia), B. sushkini (Skorikov, 1931) syn.n. (from Central Asia and Mongolia), B. morawitzianus Pittioni, 1939, syn.n. (from Mongolia), B. pseudoligusticus Podbolotskaya, 1988, syn. n. (from Kamchatka), and B. kurilensis Sakagami, 1954 (from the Kuril Islands); and (3) support for B. hongyuanensis Williams, sp.n. as a previously unrecognised vicariant sister-species from the eastern Qinghai-Tibetan Plateau.
