Queen, dealate (from type nest series, Wilson No. 905), TL 7.1, 
HL 1.10, HW 0.97 (Cl 88), ML 0.74 (MI 67), MLO 1.02, SL 0.96 
(SI 99), EL 0.26, WL 2.03 mm. Combined measurements for the 
largest queen specimen (above), another queen from the type local- 
ity, colony No. 1048, and a smaller queen from near Vanimo, are: 
TL 5.6-7. 1 , HL 0.93-1 . 10, H W 0.84-0.97 (Cl 88-90), ML 0.63-0.76 
(MI 67-72), MLO 0.87-1.03, SL 0.87-0.96 (SI 99-104), EL 0.22- 
0.26, WL 1.78-2.03 mm. 
The queen differs from accompanying workers by the usual pone- 
rine characters, and is also darker in color, prevailingly piceous, or 
even blackish in the Vanimo specimen. On trunk, centers of scutum 
and scutellum are infuscated, while marginal areas of these and 
other sclerites are lighter and more reddish. Appendages lighter, 
more yellowish. 
Male unknown. 
Described from material representing seven separate collections 
from six localities in Papua New Guinea. Holotype (MCZ) from 
Wilson’s colony No. 905, lower Busu River, Huon Peninsula, Papua 
New Guinea, 3 May 1955, a nest in rain forest in a small Zoraptera- 
stage rotten log, in a part of the log somewhat raised off the ground, 
containing one queen, about 30-40 workers, and brood of all stages, 
with pupae predominating. Abundant remains of millipedes were 
found in the brood chamber and galleries leading away. One fresh 
millipede corpse was among larvae; the prey all seemed to belong to 
one kind. 
Another colony (Wilson No. 1048) also came from the lower Busu 
River tract, 15 May 1955, from cavities in an old, hard polypore 
fungus growing on a large Passalus-^idigt log, containing a queen 
and about 75 workers, plus abundant brood of all stages, without 
notable preponderance. Half of a freshly dead millipede was found 
with the brood; the midden remains were collected (but later lost 
with the nest residue in alcohol). 
A worker and a dealate queen were found in lowland (40 m) rain 
forest next to the quarry at Km 2 on the Bewani Road, near 
Vanimo, West Sepik District, Papua New Guinea, 27 February 
1981, leg. Brown (No. 81-48). The nest was in a small rotten stick
