Phylogenetic reconstruction for P. hemera based on 660 bp of the mitochondrial cytochrome oxidase c subunit I gene (‘DNA barcode’ region) using three methods: (A) distance (Neighbor-joining), (B) Maximum likelihood, and (C) Bayesian inference. Numbers above branches indicate node support (bootstrap for A and B and posterior probability for C). Samples in blue highlight the new taxon.
