Lists and numbers of Species of the Subgenus <i>Alpinobombus</i> from previous taxonomic revisions.^a

aSpecies names and spellings are those used in the original publications. The revision by Løken did not cover the New World fauna and so did not treat B. neoboreus / B. strenuus. bCounts of split and lumped species compared to this study exclude the ‘unnamed’ taxon that we treat (conservatively) as unsampled previously. Authors of the taxon names: alpinus (Linnaeus), arcticus Kirby, balteatus Dahlbom, hyperboreus Schönherr, kincaidii Cockerell, kirbiellus Dahlbom, natvigi Richards, neoboreus Sladen, polaris Curtis, pyrrhopygus Friese, strenuus Cresson, tristis Friese.
