Phylogenetic relationships among bat fly species. The phylogenetic tree was inferred by maximum likelihood (ML) and Bayesian inference (BI) methods based on COI gene (658 bp). The values at each node represent the Bayesian posterior probability and the ML bootstrap value. A dash (–) indicates that the topologies of the ML tree and BI tree do not coincide at that branch and only the ML bootstrap value is shown. The vertical lines on the right indicate the genera or families of these bat fly species
