Habitat/Ecology. This species was found nesting in fallen rotting wood in mangrove back forest.

Remarks. A few hours after collection, majors and minors of this species were observed to each possess a pair of conspicuous opaque bright yellow spots/patches at base of gaster (first gastral tergite), spots dissipated 2 days after collection — possibly midgut or crop contents, fatty mass. The major worker confers most with P. magrettii sensu lato, with lateral face of occipital lobe and gena mostly smooth and shiny.
