Figure 3. Bayesian 50% majority rule consensus trees from (a) nuclear (NUC) and (b) mitochondrial (MIT) data sets. The numbers beside nodes represent posterior probabilities and bootstrap values for maximum-likelihood and maximumparsimony analyses, respectively. Labels A–D indicate cladogenetic events referred to in the text for Mesocarabus (in blue) and Iberian Oreocarabus (in red). Asterisks indicate incongruent nodes between MIT and NUC data sets. The species colour codes are as described in Figure 1. Voucher numbers are indicated in brackets. Specimens illustrated: 1, Carabus (Mesocarabus) lusitanicus from Salamanca, Spain; 2, Carabus (Oreocarabus) ghiliani from Segovia, Spain.
