Figure 3. Map of New Guinea sampling localities for Stegonotus (a) and mtDNA + nucDNA maximum likelihood gene tree (b). Symbols for species/clades match those on the map; * indicates bootstrap values ≥ 70. For some localities, symbols were adjusted for better visibility and so localities are approximate; see Appendix 1. for exact locality information.
