Morphological versus molecular differentiation between the dark and pale phenotype of <i>G</i>. <i>fierinensis</i>.

<p>(A) Number of ventral and dorsal scales along the body. (B) Haplotype network reconstruction including all the species of <i>Grandidierina</i>. Note the elevated amount of shared haplotypes among the two <i>G</i>. <i>fierinensis</i> phenotypes. (C) Mitochondrial divergence within the <i>G</i>. <i>fierinensis</i> complex (subtree extracted from the result of the Bayesian analysis carried out on the concatenated mtDNA sequences, cf. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0126074#pone.0126074.s002" target="_blank">S2 Appendix</a>). (D) Genetic structure inferred from four nuclear loci across 12 individuals of <i>G</i>. <i>fierinensis</i>, with K = 2; assignment probability of each specimen (N = 12) is around 50% for either cluster, independent of its phenotype.
