Figure 5 Phylogenetic trees of the concatenated mtDNA (CO1 + 16S; 1316 bp) and the full mtDNA + nDNA (CO1 + 16S + 28S + H3; 3040 bp) datasets. Posterior probabilities generated from the analyses are shown for each clade with the top numbers. Confidence values given from the bootstrapped ML method are shown for each clade with the bottom numbers. The 'x' symbols indicate varying topology between the BI and ML analyses. ML trees are reported in the Appendix for cross-reference. Species delimitation results are depicted using major color groups for the mPTP results, and subcolor groups for the ABGD results.
