Bayesian inference phylogenetic tree of Simulium taxa based on concatenated COI, 12S rRNA, 16S rRNA, and 28S rRNA sequences. Posterior probability/bootstrap [Bayesian inference (BI)/neighbour-joining (NJ)/maximum parsimony (MP)/ maximum likelihood (ML)] values are shown on the branches. The scale bar represents 0.1 substitutions per nucleotide position
