combined and based on three locality groups: Lesser Sunda, Western Australian and Victorian (see text for 
clarification) for (a) 10 skull, dental and dentary characters; and (b) seven external characters. Locality codes 
are as follows: □, Alor I.; ♦, Papua New Guinea; □, Savu 1.; 0, Sumbawa I.; +, Northern Territory; □, Flores

The Lesser Sunda Croup - externals 
DFA was run on a reduced set of five characters 
(listed in Table 4b) using the above three island 
groupings that were determined for the skull, 
dentary and dental characters. This DFA extracted 
two very significant Functions. Function 1 
explained 61.7% of the variation and Function 2, 
38.3%. A total of 88.2% of individuals were 
classified to their correct island group. 
Misclassifications were as follows: Three 
individuals from the Alor Group to the Yamdena 
population, four individuals from the Alor Group 
to the Wetar population; and one individual from 
the Wetar Group to the Yamdena population. All 
Yamdena individuals were correctly classified. 
Function 1 partially separated the Yamdena 
population from both the Alor Group and the 
Wetar population (Fig 3b). The character loading 
heavily (>0.5) on Function 1 was ear length (Table 
4b). Function 2 separated the Yamdena and Wetar 
populations (Fig. 3b). The character loading heavily 
(>0.5) on Function 2 was forearm length (Table 4b). 
The Western Australian Group - skull, dentary and 
dental characters 
DFA was run on all characters, except zygomatic 
breadth (missing in a number of specimens), for all 
locations. Four groups were identified. These 
groups were: 
(i) Western Australia; 
(ii) Queensland and Northern Territory; 
(iii) Solomons; and 
(iv) Papua New Guinea and Seram 
The DFA run with these four groups and using 
all characters, extracted two significant Functions. 
Function 1 explained 67.4% of tine variance and 
Function 2, 28.7% (Figure 4a). A total of 95% of 
individuals were classified to their correct group. 
Misclassifications were in the Queensland/NT 
Group, where one specimen classified to Western 
Australia and one to the Papua New Guinea/ 
Seram Group. 
A DFA was run again using a reduced set of five 
characters (dentary length, anteorbital foramen
