To fill this gap, we analyzed most of the European crayfish species focusing on the phylogenetic position of the endemic crayfish\n                    <jats:italic>Astacus colchicus<\/jats:italic>\n                    , inhabiting Georgia. Three mitochondrial and one nuclear marker were used to study evolutionary relationships among European crayfish species, resulting in the unique phylogenetic position of\n                    <jats:italic>A. colchicus<\/jats:italic>\n                    indicating independent species status to\n                    <jats:italic>A. astacus<\/jats:italic>\n                    . Phylogenetic analyses revealed a deep molecular divergence of\n                    <jats:italic>A. colchicus<\/jats:italic>\n                    in comparison to\n                    <jats:italic>A. astacus<\/jats:italic>\n                    (6.5\u201310.9% in mtDNA and 1.1% in nDNA) as well as to\n                    <jats:italic>Pontastacus leptodactylus<\/jats:italic>\n                    and\n                    <jats:italic>P. pachypus<\/jats:italic>\n                    (5.5\u201310.0% in mtDNA and 1.4\u20132.4% in nDNA). Absent ventral process on second male pleopod and abdominal somites II and III with pleura rounded lacking prominent spines clearly indicate taxonomic assignment to the genus\n                    <jats:italic>Astacus<\/jats:italic>\n                    ; however, the species is distributed almost in the middle of Ponto\u2010Caspian area typical by occurrence of the genus\n                    <jats:italic>Pontastacus<\/jats:italic>\n                    . Several morphological indices linked to head length, carapace, and total body length and width were found to demonstrate apparent differences between\n                    <jats:italic>A. colchicus<\/jats:italic>\n                    and\n                    <jats:italic>A. astacus<\/jats:italic>\n                    . Although this study provides a novel insight into European crayfish phylogeography, we also point out the gaps in comprehensive study of the\n                    <jats:italic>P. leptodactylus<\/jats:italic>\n                    species complex, which could reveal details about the potential species status of particular species and subspecies within this genus.\n
