Two distinct evolutionary lineages of the Astacus leptodactylus species complex (Decapoda: Astacidae) inferred by phylogenetic analyses

Narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823 species complex) is one of five European freshwater crayfish species. Even though widely distributed it hasn’t been frequently studied, and its taxonomy and systematic are unresolved. The results of recent comparative morphometrical characteristic study revealed that morphometry of Asian and European populations differ significantly. In this research, for the first time, mitochondrial molecular markers (16S rRNA and COI) were used with the aim of elucidating the phylogenetic relationship between European and Asian populations of the narrow-clawed crayfish. Analyses included crayfish from Croatia, Bulgaria, Armenia, Russia, Poland and Turkey, and three different optimality criteria were applied. Phylogenetic relationships were reconstructed using the COI data set, as well as on the concatenated one (COI + 16S rRNA). For both data sets, congruent topologies were obtained and trees were characterised by the existence of two well supported phylogroups, one that included European populations, and the other Asian. Results indicate the presence of distinct evolutionary lineages within the A. leptodactylus species complex, and corroborate previous results obtained using morphometric analyses.
