FIGURE 4 Minimum spanning network for mitochondrial ND 4 sequences retrieved from pygmy newts (Triturus rudolfi and T. pygmaeus) with a single haplogroup in red (H6), and marbled newts (T. marmoratus) with five haplogroups shown as H1 – green, H2 – light green, H3 – light blue, H4 – blue and H5 – purple. Satellite haplotypes are allocated to the nearest main haplotype, based on minimum uncorrected p-distances (details see text). Size of the circles corresponds to sample size (see legend). Internal and external branches have lengths of one or two substitutions, except for those marked with an 'x' that have 5‒7 substitutions.
