Fig. 2

Maximum likelihood tree for the clade of the subgenus Gomphostilbia based on COI sequences. Bootstrap/posterior probabilities are shown as [ML/BI] on or near the branches. Values < 50/0.50 are not shown. The scale bar represents 0.05 substitutions per nucleotide position. Three columns on the right show OTUs delimited by PTP_ML, ASAP, and GMYC delimitation analyses. Asterisks (*) with a line joining entities indicate that the taxa were identified as one OTU by ASAP and GMYC methods, respectively
