Bayesian majority-rule consensus tree of the sequenced Heterodera species COI gene in relation to other species of the Heteroderidae family. New sequences generated during this study are highlighted in bold type. Bayesian inference (BI) posterior probabilities and maximum likelihood (ML) bootstrap support values are depicted on the nodes. Support values above 90 (pp) and 70 (bs) are shown. The scale bar indicates the number of substitutions per site. NCBI GenBank accession numbers are preceded by taxa names. Different genera are highlighted in different colours (Globodera: green, Cactodera: blue, and Heterodera: yellow) as shown on top of the scale bar. Heterodera species group branches and the associated text is shown in different colours: Avenae (red), Cyperi (Magenta), Goettingiana (dark green), Humuli (dark blue), Sacchari (brown), Schachtii (purple). Meloidogyne arenaria was taken as the outgroup
