Bayesian majority-rule consensus tree reconstructed from the COI data set of the available Palearctic Prosopistoma species. The branch labelled with the GBIF code represents the newly sequenced specimen (species name in bold), other codes correspond to previously published GenBank sequences. Vertical colored boxes indicate species delimitation hypothesis according to the ASAP analysis. The outgroups are represented in grey. Circles on branches indicate Bayesian posterior probabilities of 1.
