Rooted posterior probability phylogenetic tree generated by MrBayes using the Markov chain Monte Carlo method for all the different mtDNA COI haplotype sequences (651 bp) of 1997 and 2017 samples together (n = 14) with reference sequences (n = 12, in bold) obtained from GenBank for comparison. Numbers associated with nodes indicate the posterior probability for those nodes. Horizontal bars represent genetic distances as indicated by the scale bar, vertical distances are arbitrary.
