Maximum likelihood tree of 232 18 S criconematid sequences. Substitution model GTR+G+I and 200 bootstrap replications. Each specimen is identified by a Nematode Identification number or GenBank Accession number (for taxa not sequenced by the authors), species name, and location as supplied by the author. Brackets are provided to indicate genera or specific species. Bootstrap values over 50 are applied by nodes in red. Specimens from China are highlighted in yellow.
