Here we investigate the taxonomic statuses within one of the most abundant, widespread, and polytypic Palearctic bumblebee Bombus pascuorum with a integrative approach based on genetic markers and male chemical reproductive traits. The latest review of the species defined 24 subspecies. We use this taxonomic classifications as a priori for our analyses. Our result show that all B. pascuorum taxa are conspecific and share the same male chemical reproductive traits. The genetic structure observed in one mitochondrial and two nuclear markers poorly reflect the current subspecific classification. Indeed, the concordance of population genetic differentiation, population geographic distribution, and population colour pattern similarity suggest a different meaningful prospective classification with four taxon complexes: (i) the B. pascuorum dusmeti group including all taxa from Iberian Peninsula and South/South West France, (ii) B. pascuorum rehbinderi, (iii) B. pascuorum siciliensis, and (iv) B. pascuorum floralis groups (including all other here studied taxa).} }
