FIGURE 10 in Morphology and multilocus phylogeny of the Spiny-footed Lizard (Acanthodactylus erythrurus) complex reveal two new mountain species from the Moroccan Atlas
FIGURE 10. Distribution of Acanthodactylus montanus (squares) and Acanthodactylus lacrymae (diamonds) based on specimens examined in this study. Coloured dots represent specimens of the three main phenotypes (none is monophyletic in the mtDNA or nDNA trees) in Morocco based on Bons and Geniez 1995. Specimens with the "bellii" phenotype in the High Atlas are almost certainly montanus and lacrymae. White symbols represent specimens tentatively identified as A. montanus (square) or A. lacrymae (diamond, see text). The continuous white lines represent the currently known distribution of the new species while dotted white lines represent possible extensions of the distribution if tentative identifications are correct. The dotted dark blue line represents the southernmost extension of confirmed IM clade specimens based on our field sampling.

Tree topologies have been inferred by the Maximum Likelihood approach (bootstrap proportions are presented in percentage, and are followed by the posterior probabilities obtained from the Bayesian analyses, topology not shown). Additionally, clusters inferred by barcode gap approach (ABGD) have been represented by white vertical bars reported on the mtDNA tree (A). Localities abbreviations are detailed in Table S5.
