Ranges and means (in brackets) of p-distances between (above diagonal) and within (diagonal, before slash) clades as well as K2P distances between (below diagonal) and within (diagonal, after slash) groups are shown. Letters in brackets by clade names correspond to the clade names in Fig. 8, n corresponds to the number of samples.
