A nMDS ordination (stress = 0.14) of the resemblance matrix for Umbilia armeniaca, U. hesitata and U. tomdarraghi sp. nov. B nMDS ordination (stress = 0.19) of the resemblance matrix for the three U. hesitata subspecies and U. tomdarraghi sp. nov. Shaded ellipses indicate the 95% confidence interval of taxa (species or subspecies) centroids. The coefficient of determination (R2) and probability that distances between centroids arose by random chance (P) are presented.
