Bayesian tree of 20 species in the E. parva group, based on mitochondrial CO1 sequences. Ingroup clades are coloured according to zoogeographical origin of their respective terminal branches. Outgroup branches and tip labels indicated in grey. Posterior probabilities (≥ 0.95) indicated at the nodes. Terminal branches labelled with BOLD process IDs as voucher codes. Clades (indicated with bars) and singletons constituting species are labelled with species names. Scale = 0.01 divergence in the CO1 sequence.
