Bombus robustus Smith
robustus Smith, 1854:400, examined

TAXONOMIC STATUS: See comments on B. hortulanus.

DISTRIBUTION: W Neotropical Region.

Bombus bicoloratus Smith
bicoloratus Smith, 1879:132, examined
kulingensis Cockerell, 1917:266, examined
tajushanensis Pittioni, 1949:244
12 names

TAXONOMIC STATUS: B. kulingensis has been regarded as a species separate from B. bicoloratus (e.g. Williams, 1998).

B. bicoloratus and B. kulingensis show variation in the pattern of the teeth on the inner process of the gonostylus and on the outer margin of the penis valve head, and more especially in how pronounced is the outer lateral shoulder on the penis valve just anterior to the ventro-lateral process. However, from the material examined, I believe that B. kulingensis and B. bicoloratus are morphologically closely similar. Furthermore, evidence from comparisons of DNA sequences from five genes is consistent with the two taxa being conspecific (Cameron et al., 2007 [pdf]).

DISTRIBUTION: Oriental Region.

Bombus diversus Smith
diversus Smith, 1869:207, examined
tersatus Smith, 1869:207, examined
6 names

NOMENCLATURE: Tkalcu (1965) first explicitly regarded B. diversus and B. tersatus as conspecific and, following the Principle of First Reviser (ICZN, 1999: Article 24), chose B. diversus as the valid name for the species.

DISTRIBUTION: Oriental, Japanese, Palaearctic Regions.

assamensis Bingham, 1897:550, examined

semialbopleuralis (Tkalcu, 1974b:322 [Orientalibombus])
cinnameus (Tkalcu, 1989:47 [Orientalibombus]) examined

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.
