Approximately Unbiased (AU) and Shimodaira-Hasegawa (SH) tests performed using CONSEL 0.1h. Obs. – test statistics; * P-value < 0.05, suggests that the constraints are significantly different – rejected; pal† – pal PNG, pal N-AUS, pal S-AUS; ann¶ – ann S-AUS, ann PNG-1, ann PNG-2, ann AUS. Abbreviations: ann – Culex annulirostris, pal – Culex palpalis; for lineage description refer to Figure 2 and 4.
