Bumble bee diversity and distribution in the Tropical Andes remain insufiently documented. Here, we provide the first comprehensive checklist of Bombus species for continental Ecuador, integrating data from regional museum collections, published literature, and online biodiversity databases. We further assessed Cytochrome c oxidase subunit I (COI) barcode variation in six species. In total, we documented 15 Bombus species occurring across 22 provinces of continental Ecuador. Relative to previous reports, we extend the known elevational ranges of B. transversalis and B. funebris to higher altitudes, and of B. excellens to lower elevations. Three species ( B. mexicanus , B. coccineus , and B. ephippiatus ) were excluded from the checklist, as earlier records are considered erroneous. Additionally, citizen science data revealed interactions between eight bumble bee species and 138 plant species, of which 87 are native. Our findings highlight the value of integrating natural history collections, molecular approaches, and participatory science to secure the long-term conservation of bumble bee diversity in the Tropical Andes.
