HaemorrhoidalisОпределение:Bombus haemorrhoidalis Smith TAXONOMIC STATUS: Several of these nominal taxa have been treated as separate species, most recently in the case of B. montivolans [Burma to southern China] (e.g. Tkalcu, 1968b, 1989). However, aside from differences in colour pattern, they are all closely similar in morphology with a range of variation (Williams, 1991 [pdf]). Until more evidence to the contrary is available from critical studies of patterns of variation, I shall treat them as parts of a single variable species. DISTRIBUTION: Oriental Region.
