Figure 1. Plot of measurements of mandibular basal breadth (x-axis) against oculo-malar distance (y-axis) for females (n = 62). Each symbol represents pairs of measurements from one or more specimens, with circles for workers and squares for queens. k: specimens identified from their COI barcodes as Bombus kluanensis sp. nov.; n: specimens identified from their COI barcodes as B. neoboreus; the primary type specimens for these two names are indicated with grey lines (holotype queen of B. kluanensis sp. nov.; lectotype queen of B. neoboreus). Specimens interpreted as belonging to the species B. neoboreus are shown with outline symbols; specimens interpreted as belonging to the species B. kluanensis sp. nov. are shown with filled symbols.
