Fig. 4. Discriminant analysis of U. caudimaculatus and U. emmae. The numbers refer to groupings as follows: 1 Hagen region, 2 = Mount Karimui, 3 south-east Papua, 4 = Mount Sisa, 6 = Australian mainland, 7 Dobodura, 8 Alkmaar region, 9 = Hinchinbrook Island, 10 = Utakwa River, 11 = Setakwa River. Individual specimens from Yapen (5), Yapsiei (12), Mimika (13), Kaimari (14), Aru Island (15), Telefomin (16), Torricellis (17), Mount Erimbari (18) and Weyland Range (19), fitted in after the calculation of the Functions, are plotted separately, as is the type of U. emmae (20). That U. emmae, despite being fitted into a pre-calculated analysis, fell outside the dispersion of any U. caudimaculatus sample, is highly significant.
