Phylogenetic relationships of Trichodorus hangzhouensis sp. nov. and other trichodorid nematodes based on ITS2 sequences. The Bayesian tree was inferred under the general time-reversible model of sequence evolution with correction for invariable sites and a gamma-shaped distribution (GTR+I+G). Thoracostoma trachyga served as an outgroup species. Posterior probability values exceeding 70% are given on appropriate clades.
