FIGURE 4 in Diaphorodoris alba Portmann & Sandmeier, 1960 is a valid species: molecular and morphological comparison with D. luteocincta (M. Sars, 1870) (Gastropoda: Nudibranchia)

FIGURE 4. (A) The ABGD histogram of the COI barcoding region shows the distribution of the pairwise estimated genetic distances (K2p) in intraspecific (left, light grey) and interspecific (right, dark grey) comparisons. (B) COI haplotype network showing genetic mutations occurred within Diaphorodoris species and including the out group (C) The PhyloMap-PTP visualizes the results obtained by the PTP analysis (COI) with each circle in the plot representing taxa with different species colored differently. Numbers at circles indicate the Bayesian support values of the species hypothesis. (D) 2D/3D folding analysis of the variable region L9 of the 16S RNA molecules of D. alba and D. luteocincta respectively. The * symbol indicates the diagnostic nucleotide substitutions.
