Bombus sulfureus Friese sulfureus Friese, 1905:521, examined
DISTRIBUTION: Palaearctic Region.
Bombus genalis Friese genalis Friese, 1918:84, examined
TAXONOMIC STATUS: From COI barcodes, B. genalis appears to be discrete and is likely to be separate species. DISTRIBUTION: Oriental Region.
Bombus kashmirensis Friese kashmirensis Friese, 1909[September, Tkalcu, 1974b]:673, examined stramineus Friese, 1909[September, Tkalcu, 1974b]:673 tetrachromus Cockerell, 1909[November, Tkalcu, 1974b]:397, examined pulcherrimus (Skorikov, 1914a:128 [Alpigenobombus])
TAXONOMIC STATUS: Several of these nominal taxa have been treated as separate species. However, aside from differences in colour pattern, they are closely similar in morphology with a range of variation (Williams, 1991 [pdf]:68). 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.
NOMENCLATURE: Tkalcu (1974b) first regarded B. kashmirensis and B. stramineus as conspecific and, following the Principle of First Reviser (ICZN, 1999: Article 24), chose B. kashmirensis as the name for the species.
DISTRIBUTION: Oriental Region, Palaearctic border.

Bombus vogti Friese vogti Friese, 1903:254 nigrothoracicus Friese, 1904:188, examined TAXONOMIC STATUS: B. vogti is closely similar in morphology to B. robustus, but has been considered to be a separate species (e.g. Milliron, 1973b; Asperen de Boer, 2007). B. vogti and B. robustus are usually separated using colour. Although B. robustus is variable in colour, the name is applied to individuals with extensive yellow bands, whereas the name B. vogti is used for individuals that lack yellow bands and are often almost completely black. There is very little material available of the males, but the males of B. vogti are at most only subtly different in the morphology of the genitalia. While awaiting more evidence from critical studies of patterns of variation, I treat them initially as separate species. TAXONOMIC STATUS: See comments on B. melaleucus. DISTRIBUTION: W Neotropical Region.
