1958] Broivn — Strumigenys 83 
TL 2.8, HL 0.73, WL 0.73 mm. Color a trifle darker than in 
holotype. 
This species can be separated from godeffroyi, indagatrix 
and other similar forms occurring in Borneo by its larger 
size; sparse, fine, largely erect pilosity; and slender, con- 
stricted alitrunk. 
Strumigenys mjoebergi sp. nov. 
Holotype worker: tl 2.4, HL 0.65, ml 0.29, WL 0.60 mm.; 
Cl 68, Mi 45. Very similar to S. godeffroyi , but differing 
slightly in size and proportions, and more strongly in sculp- 
ture, pilosity and color. Mandibles very slightly more curved 
than in godeffroyi , the preapical tooth long and extremely 
close to the apical fork; insertions rather widely spaced 
apart and the shafts robust. Alitrunk form much as in 
godeffroyi. Propodeal teeth acute, only weakly elevated, 
their infradental lamellae weakly convex below, thin and 
near'y transparent, without spongiform masses on their 
lateral faces. Petiolar node a little longer than broad, much 
as in godeffroyi, but the posterior and lateral spongiform 
appendages scanty. Postpetiolar node distinctly broader 
than petiolar node, a bit less than half as wide as the gaster, 
strongly convex, the surface densely punctulate-striate, 
opaque; spongiform appendages well developed, but less 
strong than in godeffroyi; much of the sides of the node 
free, especially the anterolateral surfaces. Gastric costulae 
coarse, numerous, extending i/s or more the length of the 
basal gastric tergite ; rest of gaster smooth. Alitrunk com- 
pletely punctulate and opaque. Ground pilosity of head 
consisting of short decumbent hairs, narrowly spatulate or 
clavate, much heavier than in godeffroyi. Ground pilosity 
of a'itrunk fine, sparse, very inconspicuous, reclinate. A 
few short, stubby, erect spatulate or clavate hairs on the 
occipital lobes, a pair on the center of the pronotum, another 
on the mesonotum, and a longer humeral pair ; sparse com- 
plement of distinctly spatulate erect hairs on nodes and 
gastric dorsum. Color sordid ferruginous yellow, dorsum 
of head, except occipital lobes, faintly darkened; gaster 
darker, brownish; lower halves of sides of alitrunk deep 
reddish brown; mandibles, antennae and legs yellowish.
