Bombus sylvicola Kirby
sylvicola Kirby, 1837:272
TAXONOMIC STATUS: B. sylvicola is morphologically closely similar to B. lapponicus, and it has been suggested repeatedly that they are conspecific (e.g. Sladen, 1919; Skorikov, 1922a, 1937; Pittioni, 1942, 1943; Thorp, 1962; Thorp et al., 1983).
Evidence from comparisons of DNA sequences from the 16S gene is not strong but consistent with the two taxa being separate species (Cameron et al., 2007 [pdf]). Until more evidence to the contrary is available from critical studies of patterns of variation, I shall treat them as two separate species. See also the comments on B. monticola.
