Bayesian 50% majority rule consensus tree based on cox1 sequences of Hystricella species. Posterior probability values (first value), bootstrap support values from the maximum likelihood analysis with iqtree (second value) and Garli (third value) and maximum parsimony analysis with PAUP* (fourth value) are indicated at the nodes. Only posterior probability values ≥ 0.5 and bootstrap support values ≥ 50% are shown. The inset map shows the distribution of H. bicarinata (blue), H. echinulata (green) and putative hybrids of both species (red) on Porto Santo. The tip labels on the tree are coloured accordingly. For information on vouchers, see Table 1 and the corresponding material lists under the species’ sections. The inset tree shows the position of Hystricella in relation to the other investigated genus-group taxa based on the analysis of concatenated mitochondrial and nuclear sequences as shown in Figure 3.
