Habitat/Ecology. This species is associated with primary and old or mature secondary habitat in Singapore. In old secondary forest, nestmates have been collected from the surface of a buttress root of a large tree, presumably in the vicinity of the actual nest. It is unclear exactly where actual nests may be located, i.e., in tree cavities or amidst buttress litter.

Remarks. Type locality in Singapore.
