COI DNA barcode trees. Trees of representative sequences of Papilionini reconstructed with different methods: a Bayesian inference using MrBayes (alignment partitioned by codon position, nst=6, rates=invgamma, ratepr=variable), posterior probabilities are indicated by the nodes b Maximum likelihood method RAxML (-m GTRGAMMA), bootstrap values are indicated. Posterior probabilities are shown by the nodes (omitted within species). Names of different species are shown in different colors. Sequences obtained in this work are those with “NVG-” number (see Supplementary Table 1 for complete data), others are from GenBank (http://genbank.gov/) and are labeled by accessions (letters and numbers, no dashes). Specimens with sequences from GenBank were not examined (except where a photograph was available from the BOLD database) and their identification follows original work, locality, and DNA barcode.
