Habitat/Ecology. This species is associated occasionally with primary forests, mostly with mature and/or old secondary habitats, and infrequently with young secondary forest fragments of varying levels of disturbance in Singapore. These include native-dominated secondary forest, abandoned plantation and waste woodland secondary forests. Individuals can be found foraging on leaf litter, dead wood, fallen logs, tree trunks or low foliage.

Remarks. This species has a wide range of variation in the development and shape of petiole, spines, and also pilosity. A critical revision is needed to clarify its status as a single species.
