Phylogenetic trees of parasitic nematodes inferred from the D2D3 LSU rRNA. Bootstrap values with 1000 replicates are shown next to the branches. A Phylogenetic tree of the suborder Spirurina, constructed using the neighbor-joining (NJ) method. B Phylogenetic tree of Rhigonematomorpha, constructed using the maximum likelihood (ML) method. Newly obtained sequences are in red. *The position of Rhigonematoidea sp.1. is emphasized. C Phylogenetic tree of the Thelastomatoidea constructed using the ML method. Newly obtained sequences are in red, and their hosts are in blue. **The position of Cephalobellus sp.1 is emphasized
