Small ant (minor workers approximately 2 mm long and major workers 3-4 mm long), ranging in colour from a pale yellow to a very dark brown. The first antennal segment (scape) of the minor workers far exceeds the top of the head, and is covered in many long hairs. There are no spines on the front of the body (pronotum), but two very small spines on the rear of the body (propodeum) facing almost directly up. There are many small punctations on the rear side of the body, and side of the head, but remaining body areas are smooth and shiny. The entire body is covered in many sparse, long hairs. The second waist segment (post petiole) is conspicuously swollen.
