tably longer than high; seen from above wider than long, but sides 
convex; widest near midlength. 
(5) Second gastric (true abdominal IV) segment narrower and lower 
than first segment (postpetiole), so that the gaster is gradually 
tapered caudad of I, and not constricted and recovering after. 
(6) Body, especially head, trunk and petiolar node, with deeper and 
much more distinctly developed foveolate sculpture, the punctures 
mostly 0.01-0.02 mm in diameter and densely crowded, contiguous 
on front of head between eyes and frontal lobes, becoming larger, 
mostly 0.02-0.03 mm in diameter and narrowly separated on poste- 
rior half of head, at times with intervening, indistinct, longitudinal 
strigulosity, and still coarser and more widely spaced on sides and 
underside of head and near median frontal sulcus (which reaches 
back to near the posterior quarter of HL). Trunk and petiole with 
abundant foveolae, mostly 0.02-0.04 mm in diameter, separated on 
the average by a little more than their own diameters, but more 
crowded and more elongate on sublateral strips of propodeal dor- 
sum; truncal midline strip partly open, with few foveolae. In gen- 
eral, interfoveolar surfaces smooth and shining, but lower sides of 
propodeum indistinctly, longitudinally costulate, and sides of petio- 
lar node coarsely and densely foveolate and minutely roughened, 
more or less opaque. Gaster I smooth, with scattered coarse punc- 
tures, and these become fewer and smaller still on gaster II. Mandi- 
bles smooth and shining, with scattered punctures. Antennal scapes 
and legs smooth and shining, but with fine punctulation. Propodeal 
declivity nearly smooth, but peppered with many small foveolae. 
Clypeus smooth and shining. 
(7) Pilosity and pubescence more abundant than in M. chapmani, 
most notably on mandibles and antennal scapes; decumbent pubes- 
cence on head more conspicuous, directed mesad. 
(8) Color perhaps averaging slightly darker than in M. chapmani, 
but legs and antennae tending to be lighter, more yellowish red. As 
in chapmani, the palpi are segmented 3,3, and upturned teeth are 
present, one on each labral lobe. Worker variation is very slight 
overall. The Koombooloomba series averages very slightly larger, 
and the compound eyes may be a trifle larger than in the Shipton’s 
Flat colony.
