Minimum spanning network of all identified haplotypes. Haplotype codes, and the number of sexual (S) and partenogens (P) that have a particular haplotype are indicated inside the circles. Small filled circles separating haplotypes represent a single nucleotide substitution difference. Squares represent the ancestral haplotype of every particular network. Dashed lines indicate a possible joining place for the most divergent haplotypes, whose connection to other haplotypes could not be justified by the parsimony criterion.
