Geographic variation in morphology and sequences from three loci were studied in the Moroccan skink, Chalcides mionecton. Bayesian analyses of population structure showed that five-digit individuals from southern Morocco formed one genetic cluster, while northern four- and five-digit individuals clustered together. There was strong statistical support for delimitation of C. mionecton into northern and southern species which appear to have diverged 0.46–2.66 mya.
