Species delimitation result of BPP analyses (guided and unguided) using a 13 species model as prior on the maximum number of species. The species tree is the guidetree (derived from the β-tub gene tree in Fig. 2b) used for the guided 13 species analyses. Node values (in bold and black colour) are mean posterior probabilities (of the two runs) for a species split from the guided analyses. Values following terminal names (in bold and blue colour) are mean posterior probabilities (of the two runs) of each species from the unguided analyses, accounting for phylogenetic uncertainty (i.e. not conditional on the depicted guide tree: see Fig. 5 for the MCC topology from the unguided analyses). Four probability values are given for each representing the results from the four prior variation settings in the order tau0.1theta0.1 and tau0.1theta0.01 in the upper row, tau0.01theta0.1 and tau0.01theta0.01 in the lower row. a Delimitation of 10 well-supported candidate species from the guided analyses, b Delimitation of 8 well-supported candidate species from the unguided analyses, c Delimitation of 6 conclusively supported species for which unique morphology was also found as corroborating evidence. N indicates the number of specimens
