elongate, punctures on propodeal dorsum, petiolar node and first 
gastric tergum. Antennae and legs largely smooth and shining, but 
with very fine punctulation, increasing toward extremities. Sides of 
propodeum with fine, partly broken, oblique costulation, rising 
caudad, surface here subopaque, giving way on dorsal surface to 
some partial, roughened microsculpture that renders the surface 
between coarse punctures only weakly shining. Upper propodeal 
declivity feebly, finely, transversely strigulose, smooth and shining 
below. 
Pilosity consisting of fine, tapered, erect to suberect setae of 
uneven length, mostly 0.03 to 0.25 mm long, distributed abundantly 
over dorsal surfaces of body, venter of head, and gaster, fore coxae, 
and most surfaces of appendages. Decumbent pubescence is dilute 
on dorsum of head, directed mesad; more dense on anterior surfaces 
of mid coxae, and on all tibiae and tarsi. 
Color rich, light, ferruginous red; appendages slightly lighter. 
Worker variation, apart from the slight mensurable spread, is 
weak. As already mentioned, the feeble impression, or “saddle,” in 
the posterior dorsal surface of the propodeum varies from distinct 
to almost absent in different workers. 
Queen, dealate: TL 5.2, HL 1.00, HW 1.00 (Cl 100), ML 0.55 
(MI 55), MLO 0.77, SL 0.84 (SI 84), EL 0.23, WL 1 .65, hind tibia L 
0.81 mm. Notable for size being slightly smaller than for workers of 
the same colony. Otherwise, differences are those usual between 
castes in Ponerini. Nota of pterothorax smooth and shining, with 
dispersed, small punctures. Propodeum more completely and 
strongly sculptured than in worker, subopaque, finely transversely 
strigulose, with a short, longitudinal, median sulcus or impression; 
lower declivity smooth. Color slightly darker than in worker, espe- 
cially lightly infuscated parts of cranium, pronotum, median scu- 
tum, propodeum, petiole, and first two gastric segments. 
Male unknown. 
Holotype worker (MCZ) and paratypes (MCZ, BMNH, ANIC)

ground in wet rain forest along Obi Obi Creek, below and just west 
of Montville, Blackall Range, Queensland, Australia, 20 May, 1951, 
leg. Brown. The nest contained 20-30 workers, larvae (since lost 
together with prey remains), and two dealate queens. The forest at 
the type locality has since been destroyed (fide P.J. Darlington,
