framed by lateral and posterior carinae. Sides of mesosoma generally 
smooth, ventral parts of mesepisternum, metepisternal area, and sides 
of propodeum obscurely roughened. Petiole, postpetiole and gaster, 
antennae and legs, smooth and shining. 
Pilosity moderately long and abundant on head and mesosoma, 
erect to sub-erect, longest on clypeus, crown of head, and pronotal 
dorsum; shorter erert hairs on scape, sub-erect ones on mandibles, 
funiculus and legs. Hairs lacking on sides of mesosoma. Petiolar and 
postpetiolar tergites each with three bilaterally symmetrical pairs of 
hairs (positions as in Figure 2), postpetiolar sternite with a single 
pair. Gaster very finely pilose apically, its first tergite completely 
bare. Pubescence lacking. 
Color rich golden sienna-brown, mandibles, clypeus, antennae and 
legs lighter, eyes black, pilosity whitish. 
Type-locality. Clump Point, west of Tully, N. Queensland. 
The holotype was taken in a rotting wood fragment on the floor 
of very disturbed, depauperate rain forest, a few feet above sea level 
(June 25, 1962; R. W. Taylor acc. 1746). 
Paratype workers. Three specimens collected with the holotype 
resemble it closely; they have the following dimensions: HL 0.82- 
0.88 mm; HW 0.87-0.96 mm; Cl 106-109; SL 0.72-0.75 mm; SI 
78-83; PW 0.52-0.57 mm; WL 0.77-0.79 mm; Propodeal Spine L 
0.32-0.35 mm; Petiole L 0.29-0.33 mm; Postpetiole Height 0.28-0.30 
mm. 
An additional specimen from rain forest at Thornton Peak (Mt. 
Alexander), north-west of Daintree, N. Queensland (elevation not 
specified but probably + 1000 ft (Darlington, i960: 1 1 7 ) , December 
20-23, I 957i P- F. Darlington) has: HL 0.85 mm; HW 0.95 mm; 
Cl 1 12; SL 0.75 mm; SI 79; PW 0.53 mm; WL 0.78 mm; Pro- 
podeal Spine L 0.32 mm; Petiole L 0.28 mm; Postpetiole Height 
0.29 mm. 
This species may show slight unimodal polymorphism. In the short 
series available SL, and the mesosomal dimensions PW and WL are 
negatively allometric relative to HW, while HL is positively allo- 
metric. 
Distribution and Material Examined. Known only from the five 
workers listed above. Clump Point and Thorton Peak are within the 
area of the main “base-of-peninsula” rain forest system of North 
Queensland. 
Type deposition. Holotype and three paratypes in Museum of 
Comparative Zoology (MCZ) at Harvard University (Type No.
