Phylogeographic analysis of Brachyptera seticornis, based on the COI gene fragment, 658 bp in length. A ML phylogenetic tree. The terminals correspond to the BOLD IDs. Individual collected in the present study is marked with an asterisk. Bars in different colours represent the results of species delimitation methods; B Phylogenetic network obtained by the statistical parsimony (TCS network). Colour coding corresponds to the groups in the species tree; C Geographical distribution of analysed haplotypes. Colour coding corresponds to the groups in the species tree and the TCS network.
