Ultrametric time-calibrated trees obtained with BEAST for each individual (left) and combined datasets (right) of Carabus. Trees obtained with the ingroup dataset (including only Carabus species) and locus-specific optimal parameters. Nodes represented by black-filled circles received posterior probabilities (pp) higher than 0.9, bars represent 95% HPD intervals for node ages in Ma. The 95% HPD intervals of the TMRCA of Carabus are shaded in grey. Pie charts represent support (black, pp ≥ 0.95; dark grey, pp ≥ 0.85; light grey, pp ≥ 0.50; white, node not recovered) in MrBayes (outgroup dataset) and BEAST (outgroup and ingroup datasets) for calibration nodes A, B and C, for the different gene fragments: cox1-A (1), cox1-B (2), cob (3), nd5 (4), rrnL (5), LSU-A (6), LSU-B (7), ITS2 (8), HUWE1 (9), MIT (10), NUC (11) and MIT-NUC (12).
