The worker described by Wheeler is estimated to be about 5.5 mm (0.22 in).
The exoskeleton is a mix of smooth and ridged textures, with longitudinal ridges on the head, petiole and postpetiol, while the mesopleurae and epinotum have transverse ridges.
In contrast the gaster, pronotum and mandibles plus clypeus are shining and smooth.
The overall coloration of the workers is black, with a silvery luster present on most of the body.
The large head is rectangular, narrowing to a prominent concave rear margin.
The eyes are large and positioned near the front of the head, while there are no ocelli visible on the head.
The mandibles are elongated, slightly curved near the bases, and narrow.
They are separated into distinct base and masticatory areas, with very small uniform teeth populating the whole length of the chewing edge.

The thorax forms a slender neck from the prothorax, on which the head is connected, and the remainder of the thorax is narrower in width than the head.
The upper surface of the thorax is divided by a distinct constriction between the mesonotum and epinotum.
Two small spines rise from the rear edge of the epinotum.
The petiole is thin with no teeth on the underside and only a slight thickening into a node on the upper surface.
The abdominal segment connected to the petiole is modified into a postpetiole that is thicker and a little shorter than the petiole, and which has a distinct convex curve to the upper surface.
Of similar size as the head, the gaster has a notably enlarged first segment and in the holotype specimen the remaining abdominal segments are withdrawn into it.
