The extent of what is known about this species' biology is an eclectic set of observations. An arboreal species, nests are probably constructed of fibre. A solitary female caught in eastern Ghana was running on a tree trunk with several Polyrhachis fissa workers. A recently dealated female was recorded in Ghana in June. (Bolton 1973)

Bolton (1973) - TL 5.0-5.4, HL 1.26-1.29, HW 1.00-1.04, CI 78-82, SL 1.33-1.48, SI 133-142, PW 0.96-1.00, MTL 1.40-1.48. (7 measured.)
Anterior clypeal margin arcuate and entire. Eyes convex, the sides of the head in front of the eyes more or less straight and somewhat convergent anteriorly. Behind the eyes the sides round into the convex occipital margin. Alitrunk marginate laterally throughout its length, the margination interrupted only at the sutures. Constituent segments of dorsum of alitrunk transversely convex. Pronotum armed with a pair of spines, propodeum with a pair of variable teeth. Usually these are present as a pair of minute, upcurved denticles, but may be reduced to a pair of tubercles or even be absent. In one specimen a minute tubercle is present on one side but absent from the other. Promesonotal suture incised, metanotal groove impressed. In profile the propodeum rises vertically from the metanotal groove, passes through a strongly convex curve dorsally and then slopes backwards to the junction of the dorsum and the declivity. In dorsal view the marginations of the propodeum are slightly divergent posteriorly. Petiole with a blunt process ventrally, armed with four spines, the dorsal pair longer than the laterals, straight, directed slightly outwards and backwards. Lateral pair of spines directed outwards and very slightly upcurved. Anterior face of first gastral segment only very shallowly concave.
Body devoid of erect hairs except upon the anterior clypeal margin and the gastral apex. A fine pubescence present everywhere.
Sculpturation everywhere of a fine reticulation. Colour black, the tibiae lighter, brown to orange-brown, dully shining.
