Recent molecular analyses of the stone crayfish have revealed a high degree of genetic diversity. The greatest diversity is found in the western Balkans (Dinarides), where more than half of the known phylogroups exist in a relatively small geographical area, some of them having smaller distribution range than the others. While the Croatian and Slovenian parts of the Austropotamobius torrentium areal are well described, data from Bosnia and Herzegovina (BA) are lacking. Here we provide data from 13 different localities in the northwestern parts of BA. We analysed two mtDNA markers and the results revealed high genetic diversity with a total of 12 MT-COI and nine MT-16SrRNA haplotypes, with the majority of novel haplotypes. Both genes confirmed the presence of two known phylogroups and the discovery of a new group named VOJ. The CSE phylogroup was the most widespread and restricted to the Vrbas basin. The first detection of the BAN phylogroup in BA indicates its wider distribution and connects previously isolated findings from Croatia. The discovery of 18 unique haplotypes as well as a new phylogroup is of particular interest, but further studies are needed to clarify their exact relationship to other lineages.
