Table 4 Summary of clade support (Bayesian posterior probabilities (PP) values) for each species and locus or combination of loci. Green cells represent the PP values of species which are supported as distinct species, purple cells represent the PP values of species which are indistinct from one other species; while white cells represent species which cannot be distinguished from several other species for the given locus or combination of loci. The K2P inter-/intraspecies variation ratio as well as the number of species in the three different coloured categories are indicated per locus below the table. Abbreviations of loci follow Table 1.
