Can be distinguished by the hair on the thoracic dorsum being uniformly bright yellow (cf.  B. keriensis,  B. separandus, etc.).  Males Body length 12–16 mm. Can be distinguished by the unique combination of having the eyes slightly enlarged relative to female eye and the hair of the thoracic dorsum being uniformly bright yellow (cf.  B. eriophorus,  B. qilianensis). Genitalia ( Fig. 196) with the gonostylus as long as broad, reduced as a rounded flat scale with the inner basal process reduced to a tooth (cf. rufipes-group, festivus-group,  rufofasciatus-group); volsella with the inner distal corner broadly produced but without a narrow hook (cf. rufipes-group, festivus-group,  rufofasciatus-group); eye slightly enlarged relative to female eye.    Material examined   Syntype   INDIA• ♀(queen), syntypeof  Lapidariobombus semenovianusSkorikov, 1914 ( Williams 1991); Kashmir, Ladakh, Stakmo pass;  13 Jul. 1912; G.
