Popis: Although only distantly related, Anomalobuthus and Liobuthus are monotypic and sympatric scorpion genera with psammophilic phenotypes well-suited to the dune communities of the Karakum and Kyzylkum deserts of Central Asia. We predicted that this unique combination of phenotypic convergence and sympatry should have resulted in shared phylogeographic histories. We tested this hypothesis by using mitochondrial DNA data and molecular dating techniques to reconstruct the matrilineal genealogies of A. rickmersi and L. kessleri. We also developed current and late-glacial species distribution models and landscape interpolations of genetic distances to assess the influence of historical barriers and Pleistocene climates on the phylogeography of each species. Both genera exhibited signals of restricted gene flow across the Amu Darya River, supporting our prediction of mutual histories. Levels of initial genetic differentiation within each genus date to the Late Miocene to late Pliocene. Distribution models...
