a) Two true species trees used for simulating sequence data under the multispecies coalescent model. Parameters in the model include the three species divergence times ($\tau$s) and the population size parameters ($\theta$s) for the seven species. Each species is split into two populations in the species-delimitation analysis by bpp, with eight populations on the guide tree. Either three or five sequences are sampled from each populations, with either 24 or 40 sequences in the alignment at each locus. b) Two inferred population (guide) trees, with interior nodes labeled.
