Worker
Crawley (1925) - Length 4 mm.

Dull reddish-brown; head darker than thorax, gaster darker than head, except the extreme base; mandibles, antennae, cheeks, and tarsi castaneous.

Body, including legs and antennae, covered. with a moderately long abundant pilosity.

Head slightly longer than broad, somewhat narrower at the occipital angles, which are rounded. Occipital border concave in centre. Eyes somewhat in front of middle of sides of head, which are feebly convex. Scapes reach two-thirds of the distance from their base to the occiput. A broad and shallow scrobe extends to the end of the scapes. Frontal carinre short, continued by the edge of the scrobe. Mandibles with five teeth, the three apical ones large and acute, the others indistinct. Clypeus fiat, with a central ridge, the anterior border sinuate, excavate in centre.

Joints 2 to 4 of funiculus about as wide as long, the others increasing in size to the club, of which the apical joint is rather longer than the other two together.

Pronotum two-thirds as wide behind as in front, the anterior angles rounded, no signs of teeth. Mesonotuni has feeble lateral ridges.

Base of epinotum longer than the declivity, slightly concave in centre, the angle between the two faces rounded. Declivity convex and feebly marginate. Petiole, seen from above, three-fifths as wide as long, slightly wider behind, the sides feebly convex. In profile the petiole is rounded along the top, descending more rapidly in front; beneath anteriorly is a tooth. Postpetiole, seen from above, almost globular, in profile it is rounded above and almost flat beneath. Gaster broadly oval.

Moderately shining. Mandibles superficially striate with minute points. Clypeus shining; besides the central ridge there is one on each side, and sometimes a smaller incomplete one beyond.

Head between antennal scrobes regularly and widely striate, the striae become more superficial and wider apart as the vertex is reached, where also there are a few scattered punctures. Between the striae the surface is slightly roughened, but shining. Cheeks, sides, and underneath of head longitudinally striate, but not so regularly, the lines curving and having a reticular tendency. Scrobe finely reticulate only. Dorsum of pro-mesonotum striate similarly to the head, but less strongly, and the mesonotum has in addition a reticulate ground sculpture. Base of epinotum coarsely rugose, the declivity reticulate. Sides of thorax longitudinally striate, but mesopleurae are almost entirely reticulate only. Pedicel with a dense ground reticulate sculpture; the first node has also a few longitudinal ridges and the second a few elongate punctures. Extreme base of gaster longitudinally striate, the rest almost entirely smooth and shining.
