straight (feebly convex) profile, without indication of meta- 
notal groove. Propodeal teeth small, acute, subtended by 
ventrally broadened and convex lamellae without lateral 
spongiform facing. Petiolar node gently rounded above, 
longer than broad and slightly longer than its peduncle, its 
spongiform appendages limited to a moderate posterior rim 
and an anteriorly lobate midventral strip. Postpetiolar disc 
convex, about half again as broad as long and approximately 
half as broad as the gaster, with well developed appendages. 
Gaster narrow ; basal costulae very short, somewhat spongi- 
form in consistency. Postpetiolar disc, gastric dorsum, fore 
coxae, propodeal declivity and lower halves of sides of ali- 
trunk nearly or quite smooth, strongly shining. Remainder 
of body densely punctulate, opaque ; pronotum laterally with 
weak substriation. 
Ground pilosity of head consisting of fairly conspicuous 
short, subreclinate spatulate hairs, anteriorly directed, form- 
ing regular fringes on anterior dorsal scrobe borders, an- 
teior clypeal border and anterior borders of scapes, here 
directed toward scape apices. Promesonotum and dorsal 
surfaces of mandibles with similar hairs, but less conspic- 
uous, directed mesad. Erect and inclined pilosity of short, 
stiff hairs with distinctly spatulate apices: 6 fringing pos- 
terior occipital margin, one on each lateral occipital margin, 
one pair on humeri and one pair on mesonotum, sparse rows 
of 4 each on petiole, postpetiole and gastric dorsum. Ventral 
side of head, and gaster near apex, with a few short fine 
hairs. Pilosity of appendages rather sparse, fine, subrecli- 
nate. Color rather uniform light ferruginous. 
Holotype [mcz] taken at 4000 feet altitude on Mt. Pen- 
rissen, Sarawak (Borneo) by E. Mjoberg, with no further 
data, but presumably from rotten wood. Seven paratype 
workers taken with the holotype [MCZ, USNM] show very 
little variation, tl 2. 3-2. 4, hl 0.61-0.63, ml 0.22, wl 0.61- 
0.62 mm.; Cl 70-73, mi 35-36. Certain specimens show a 
slight effacement of the pronotal punctulation, giving this 
region a subopaque appearance somewhat like that of S. 
godeffroyi. 
The dea T ate female paratype, taken with the holotype, has 
a very high-bulking thorax; mesonotum densely and finely
