Neighbor-joining tree of the four Thai species in the S. chumpornense subgroup of the S. varicorne species-group based on 658 bp COI gene sequences. Bootstrap and posterior probability values (NJ/BI) are shown above each branch. The scale bar represents 0.01 substitutions per nucleotide position. Sequences in bold type are generated in this study.
