Geographic distribution modeling and area evaluation of Bombus morio and B. pauloensis, and the clades found in B. pauloensis from mitochondrial DNA data. C: central; N: north; S: south. LIG: Last Interglacial (~120,000–140,000 years BP); LGM: Last Glacial Maximum (~21,000 years BP). Graphics represent the distributional area reduction from LIG until current data, in suitability thresholds of maximum, medium and minimum probabilities (higher than 75%, higher than 50% and higher than 25%, respectively) of predicted presence. The axes of ordinates show the occupied area in a normalized ratio
