Phylogenetic and haplotype network trees constructed using MT-COI dataset. a: Network Median Joining haplotype tree; red − Vrbas basin and green − Una. Haplotype node size is related to a sample size. Black dots (mv)-median vector. Haplotype ratio is distributed by phylogroups: CSE- central and south-eastern Europe; SB- south Balkan; ZV- Zeleni Vir; LD- Lika and Dalmatia; KOR- Kordun; BAN- Banovina; GK- Gorski Kotar; ŽPB- Žumberak, Plitvice and Bjelolasica; APU- Apuseni Mt.; Vojskova − VOJ*. b: ML phylogenetic tree with bootstrap values of both methods, ML and BI, indicated in the nodes. Dash indicates values <50. Some branches that contain only sequences imported from the GenBank are condensed. New samples from this study are marked with circles that correspond to phylogroup colors.
