Habitat/Ecology. This species appears to be associated mainly with disturbed young or mature secondary forest, where the ants were found in leaf litter.

Remarks. Deemed to be African in origin (Bolton 2000), S. rogeri was probably introduced to Singapore via human commerce – which has been attributed to for the species’ spread to other parts of the world (Wetterer 2012c).
