FIGURE 4. Phylogenetic trees obtained by Bayesian inference (BI) analysis of samples of Coenagrion sp., based on gene sequences of two nDNA fragments: arginine methyltransferase (PRMT) (n=12, 706 bp) and phosphoglucose isomerase (PGI- 1219) (n=12, 605 bp), Bayesian posterior probabilities and bootstrap values for maximum likelihood are indicated at tree nodes. Tree topologies from ML analysis were identical to the BI analysis at both genes.
