The evolutionary history was inferred from nucleotide sequences using the neighbour-joining method and 500 bootstrap replications. Codon positions included were 1st plus 2nd plus 3rd. Non-coding positions were excluded from the analysis. All positions containing gaps and missing data were eliminated. There were in total 5,622 positions in the final dataset. Evolutionary analyses were conducted in MEGA7. Reconstructions using the Maximum Likelihood method provided a similar topology.
