Abstract (EN): Although Odonata are a key component of many freshwater ecosystems, their taxonomy and evolutionary history is still far from being well resolved. In the present study, we report the first molecular phylogeny for the Western Palaearctic Cordulegaster genus (Odonata: Anisoptera: Cordulegastridae). We sequenced fragments of both mitochondrial and nuclear genes [cytochrome c oxidase I (COI) and Internal Transcribed Spacer-1 (ITS-1)] from eight species and 13 subspecies, from western, southern and central Europe, Turkey, and Morocco. Our data support the existence of two major groups corresponding to the traditional boltonii- and bidentata-groups. Both groups are monophyletic based on COI sequences and the distinctiveness of Cordulegaster princeps, Cordulegaster trinacriae, Cordulegaster picta and Cordulegaster heros relative to Cordulegaster boltonii, and Cordulegaster helladica and Cordulegaster insignis relative to Cordulegaster bidentata, is confirmed. All species are also monophyletic for ITS-1, with the exception of Cordulegaster helladica buchholzi, which shares the haplotype with C.insignis. Although moderate levels of genetic diversity were found within C.boltonii, there was no clear separation among the four subspecies, with the exception of the populations of Cordulegaster boltonii algirica from North Africa. Similarly, no genetic differentiation was found between the two subspecies of C.bidentata, Cordulegaster bidentata bidentata and Cordulegaster bidenta sicilica.(c) 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2014, 111, 49-57.
