Clypeal carinae moderately developed but distinct, widely separated and divergent anteriorly. Median portion of clypeus shallowly prominent and unarmed, its anterior margin more or less transverse between the apices of the clypeal carinae. Maximum diameter of eye 0.20-0.23 x HW. In profile the eye conspicuously longer than high and consisting of an outer ring of ommatidia enclosing a single longitudinal row of 2-3 ommatidia. Sometimes one or two other ommatidia may also be enclosed in the ring, but this is rare. In full-face view the eyes distinctly in front of the midlength of the sides. Antennae 11-segmented. Scapes, when laid straight back from their insertions, failing to reach the occipital margins. Promesonotum in profile more or less flat posteriorly, sloping to the narrow but impressed metanotal groove. Propodeum in profile with dorsum and declivity forming a single smooth broad curve. Petiole node low and subconical, narrowly rounded above. Subpetiolar process a narrow inconspicuous strip below the short anterior peduncle. Postpetiole smaller than petiole in profile, lower and much more broadly rounded. All dorsal surfaces of head and body with standing hairs, the promesonotum characteristically with a distinct clump of 5-6 (rarely 4) pairs of standing hairs on the anterior half of the pronotum and more sparsely distributed pairs of hairs behind this. Sculpture absent except for metanotal cross-ribs and sometimes with faint shagreening on the mesopleuron. Colour ranging from dull yellow to medium brown.
