Global known distribution of Podarcis bocagei (red dots) and P. vaucheri from Morocco and Algeria (green squares) (a; modified from Kaliontzopoulou et al. 2011) and localization of the sampled populations (b: P. bocagei, c: P. vaucheri; in larger symbols, with white outline, codes as in SM 1), and measured biometric traits (d), landmarks used for head shape analyses (e) and counted scalation characters (f). See methods for variable abbreviations. The black squares in the global map (a) denote the areas used for interpolating morphological traits in each of the species
