Distribution of taxa in the nogelii complex. Shapes represent morphological identifications (□ = nogelii, ∆ = nesimachus, ○ = romanovi), colors represent COI barcode haplotypes (red = nogelii haplotypes, orange = nesimachus haplotypes, green = romanovi haplotypes). Sites with shared or more than one haplotypes are circled. Records in gray are concatenated from literature. Approximate taxon boundaries are inferred from represented haplotypes. For haplotype network, see Figure 3.
