Figure 2: The taxon identification phenogram of Hemibagrus inferred using the Neighbor-Joining method in MEGA 5.2. The optimal tree with the sum of branch length = 1.86668598 is shown. Bootstrap values are indicated on each node of the tree (500 replicates). Bar indicates the number of substitutions changes estimated using Tamura-Nei distance considering invariable site contribution (+I). The analysis involved 119 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 597 positions in the final dataset.
