Habitat/Ecology. This species was mainly found in old or mature secondary forests in Singapore, sometimes at bases of trees at forest or trail edges. Nests were collected from fallen rotting wood or large branches, sometimes in root-soil-substrate matrices at bases of trees.

Remarks. Morphologically very similar to the presumably widespread invasive B. chinensis, B. luteipes may be differentiated from the former based on characters illustrated in Yashiro et al. (2010). An affiliated unnamed species, currently identified as Brachyponera sp.1 .of.SKY (= Pachycondyla sp. 28.of.SKY), was found to be common across secondary forests and seemingly more widespread than B. luteipes .
