The list presented here is a checklist of global bumblebee [1] species (Tribe Bombini) based on the Bombus phylogeny presented by Cameron et al (2007) [2] and grouped by subgenus following the revision of Williams et al (2008). [3]
Bombus occidentalis, the western bumble bee, is one of around 30 bumble bee species present in the western United States and western Canada. [1] A recent review of all of its close relatives worldwide appears to have confirmed its status as a separate species.
