Additional paratype workers. Three workers from Beatrice River, 
Crawford’s Lookout, N. Queensland (elevation probably c. 1000 ft. 
(Darlington, i960: 118), rain forest, February 21-22, 1958; 
Darlingtons) and a single worker from Kuranda, N. Queensland 
(1100 ft, rain forest, July 4, 1962, R. W. Taylor acc. 1358) have 
the following dimensions (Crawford’s Lookout material cited first) : 
HL 0.86-0.89, 0.89 mm; HW 0.87-0.90, 0.93 mm; Cl 101-102, 105; 
SL 0.88-0.89, 0.90 mm; SI 99-101, 97; PW 0.45-0.47, 0.47 mm; 
WL 0.84-0.85, 0.88 mm; Propodeal Spine L 0.27-0.28, 0.31 mm; 
Petiole L 0.31-0.33, 0.33 mm; Postpetiole Height 0.29-0.31, 0.31 mm. 
Polymorphism weak, as in P. foveolatus — SL, PW and WL nega- 
tively allometric relative to HW, HL positively allometric. 
Paratype females. Two females are present in the type series, one 
from the holotype nest, the other from the Crawford’s Lookout 
collection. Dimensions (Lake Eacham specimen cited first) : HL 
0.96, 0.95 mm; HW 1.04, 1.02 mm; Cl 109, 108; SL 0.95, 0.92 
mm; SI 91, 90; Scutum W 0.67, 0.65 mm; WL 1.09, 1.04 mm; 
Propodeal Spine L 0.32, 0.3 1 mm; Petiole L 0.38, 0.38 mm; Post- 
petiole Height 0.35, 0.35 mm; Eye Diameter 0.17, 0.17 mm; Ocular 
Index 16, 17. General features as in Figures 5 and 6. Pronotum 
without humeral spines; mesoscutum lacking parapsidal lines, pro- 
podeal spines diverging from dorsal midline at angles of 30 and 33 
degrees. Mesonotal sclerites moderately coarsely longitudinally 
costulate, with vestiges of interstitial foveae. Pilosity as in worker; 
petiolar and postpetiolar hairs similarly arrayed, the petiolar peduncle 
with an additional pair of lateral hairs. 
Color as in worker; each ocellus with an adjacent black spot; the 
mesosomal suture lines darkly infuscated. 
Distribution and material examined. Known only from the 19 
workers and two females discussed above. Lake Eacham, Crawford’s 
Lookout and Kuranda are all at moderately high elevations on the 
Atherton Tableland, within the compass of the main “base-of- 
peninsula” rain forest system of N. Queensland. 
Type deposition. Holotype, 11 paratype workers and paratype 
female (from holotype nest) in MCZ (Type No. 31 153); four 
paratype workers and female in CSIRO; single paratypes in Queens- 
land Museum, Brisbane; National Museum of Victoria, Melbourne; 
and British Museum (Nat. Hist.), London. 
3. Pristomyrmex quadridentatus (Ern. Andre) 
(Figs. 7-10, Plate 3) 
Odontomyrmex quadridentatus Ern. Andre, 1905, Rev. Ent. Caen., 24: 207, 
worker. Type-locality: Sydney.
