Haplotype network of (A) combined ND4 - cyt b genes, and (B) D2-28S gene of the Pacific group species/lineages.

<p>The size of the circles indicates the haplotype frequency. Mutation number for every node (>5 for mtDNA and >1 for D2-28S gene) are detailed in (A) and (B) in red. Color of the pie indicates the species/lineage of the Pacific group: <i>R. pallescens</i> I in red; <i>R. pallescens</i> II in blue; <i>R. colombiensis</i> in yellow; and <i>R. ecuadoriensis</i> in green. Line in bold in (B) shows two mutation steps separating <i>R. colombiensis</i> from the central haplotype.
