Differentiation and taxonomy of the Rock Lizards Darevskia (Saxicola) (Sauria: Lacertidae) according to morphological and molecular analyses

The results of statistical analysis of morphological characters and the study of the cytochrome b gene variability (mtDNA) of rock lizards of the Darevskia (saxicola) complex distributed in the Caucasus and the Crimea, have shown significant differentiation within this complex, assuming specific independence of D. szczerbaki (Lukina, 1963) and subspecific status of recently described D. brauneri myusserica Doronin, 2011. According to our data, within D. brauneri (Mehely, 1909) only two forms of subspecific status can be distinguished, namely D. b. brauneri and D. b. myusserica. In our opinion, Lacerta saxicola darevskii Szczerbak, 1962 (= D. brauneri darevskii) should be considered to be a junior synonym of D. b. brauneri. The possible scenarios of range formation in the Darevskia (saxicola) complex are discussed.
