Phylogenetic relationships and geographic distribution of Berberomeloe insignis sensu lato. The mitochondrial phylogenetic tree (Cox1 and 16S) and the ITS2 allelic network (adapted from Sánchez-Vialas et al. 2023) are shown. The map illustrates the geographic range of each major clade, with distinct colors matching those in the phylogeny and allelic network. Cephalic phenotypes for each clade are also depicted. Clade labelling follows Sánchez-Vialas et al. (2023). Nodal support of PP > 90 is indicated by a dot.
