S2 Figure. Test results of biogeographical scenarios 1-CG and 2-CG concerning origin of the Creatonotos gangis populations under an ABC framework using the COI gene sequences. (a) Pre-evaluation of prior combinations of scenarios. (b)-(c). Model checking to measure a mismatch between the parameters of posterior combination and observed data sets in scenarios 1- CG (b) and 2- CG (c). Scenarios are illustrated in Figure 4. A description of basic assumptions with prior settings for each scenario is presented in Supplementary Table 2.
