Phylogenetic tree generated by maximum likelihood analysis based on the combined sequences of COI and CAD sequence data of Eccoptopterus. Bootstrap values for maximum likelihood (ML) and maximum parsimony (MP) equal to or greater than 70% and Bayesian posterior probabilities (BPP) equal or greater than 0.95 are placed above the branches, respectively. The new species are indicated in blue area. The tree is rooted to Anisandrus cristatus.
