Note: Posterior probabilities for correct delimitation models are given for the results from BPP: 
of the one-species model for Scenario I; 
of the two-species model for Scenarios II and III; 
of the five-species model for Scenario IV; and 
of the four-species model for Scenario V. The numbers of delimited OTUs for each simulated species are reported for both GMYC and PTP.
