The results of species delimitation by STACEY add-on of BEAST v. 2 in the series Flavipedes (A) and Spelaei (B) with the chosen collapseheight parameter = 0.001. The similarity matrices give the posterior probability of every two isolates belonging to the same multi-species coalescent cluster (tentative species). The darkest brown shade corresponds to a posterior probability of 1, while a white colour is equal to 0. The horizontal and vertical lines in the similarity matrices depict the species boundaries proposed by the analysis. Only strains with unique multilocus haplotypes were used in the analysis (strains with identical haplotype are represented by one tip in the tree). Ex-type isolates are highlighted with bold font. Presented phylogenetic trees were calculated in STACEY.
