Figure 2:

Statistical parsimony network showing the phylogenetic relationships between the D2–D3 of 28S rRNA gene sequences of Meloidogyne species from the tropical RKN complex. The sequences of each species are marked by different colors. Pies (circles) represent sequences of each species with the same haplotype and their size is proportional to the number of these sequences in the samples. Numbers of nucleotide differences between the sequences are indicated on lines connecting the pies. Small black dots represent missing haplotypes.

Figure 4:

Statistical parsimony network showing the phylogenetic relationships between intergenic COII-16S gene sequences of Meloidogyne species having a long intergenic region. The sequences of each species are marked by different colors. Pies (circles) represent sequences of each species with the same haplotype and their size is proportional to the number of these sequences in the samples. Numbers of nucleotide differences between the sequences are indicated on lines connecting the pies. Small black dots represent missing haplotypes. * - identified in GenBank as Meloidogyne sp.
