Abstract Lucanidae is a saproxylic family of beetles with a cosmopolitan distribution and an important contribution to the decomposition of dead wood and the recycling of nutrients in forest ecosystems. The genus Dorcus has been the subject of longterm phylogenetic controversies, reflected in plenty of taxonomic reviews. There are 4 species in the European area, 2 of which are distributed in Greece (D. parallelipipedus and D. peyronis) with the second one being extremely rare. The present study investigated the phylogenetic relationships of the 4 European species of the genus with emphasis on Greece (D. parallelipipedus, D. alexisi, D. musimon and D. peyronis) using mitochondrial and nuclear markers, including individuals from 23 different sites of Greek mainland and Crete and 7 from Cyprus, Sardinia, Turkey, Spain and Italy. The phylogenetic tree indicates the presence of two branches: the one includes D. parallelipipedus of the Mediterranean area without significant intraspecific genetic differentiation (~ 4%) and D. alexisi and D. musimon (5% and 8% respectively from the first one). The second includes D. peyronis of Crete and Turkey, with a great differentiation from the rest Dorcus spp. (25%) and phylogenetically more closely related to other family members (20%). The above leads to the need for taxonomic revision of the genus Dorcus (paraplyletic). Based on the topology of the tree and the analysis of the populations (the entire Mediterranean) as well as the dating of the data, there is likely an old dispersion of the taxon (active or passive) in the Mediterranean region.
