1.08-1.12 mm; SI 85, 79-82; Scutum W 0.67, 0.78-0.84 mm; WL 
1. 1 9, 1.26-1.36 mm; Propodeal Spine L 0.33, 0.35-0.39 mm; Petiole 
L 0.41, 0.44-0.48 mm; Postpetiole Height 0.39, 0.41-0.45 mm; Eye 
Diameter 0.24, 0.26-0.27 mm; Ocular Index 20, 19-20. Negative 
allometry of scape length and head length, relative to head width, is 
indicated. General features as in Figures 13 and 14. Distinguished 
from P. quadridentatus by very different proportions and coloration. 
Structure of clypeal apron variable, usually as in Figure 13; the 
median projection narrowed with reduced teeth in one specimen, 
bidentate in another, and completely edentate in a third. Transverse 
pronotal carina distinct. Pronotal spines variable, ranging from low 
rounded tubercles to small acute teeth (maximally about 0.03 mm 
long) , with no apparent allometric tendency. Parapsidal lines feeble 
to moderately distinct. Propodeal spines almost invariable, their bases 
bridged by a low carina. Metapleural spines acute, distinctly shorter 
than propodeals. 
Color and pilosity as in worker, mesosomal suture lines and alary 
sclerites infuscated dark brown. 
Distribution and Material Examined. All records of P. wheeleri 
are from S. E. Queensland and N.E. New South Wales, between
