Habitat/Ecology. A colony of this species was found in a carton nest with Polyrhachis sp., in primary or mature secondary forest. The ants were also found nesting in hanging dead twigs in similar forest.

Remarks. Previously reported literature records of the species in Singapore (i.e., Viehmeyer 1916, Overbeck 1924) actually refer to specimens from ‘St Barbe Island’, part of the Riau Island Archipelago in Indonesia, and not in Singapore. Thus, at the time of writing, this is the only known physical record of the species in Singapore.
