(Lattke, 2004)

Nothing is known about the biology of this species.


Lattke (2004) - Head elongate with evenly convex lateral margins in frontal view, posterior margin concave, frons punctate over smooth cuticle; scape punctate with scattered brief longitudinal strigulae, abundant semi erect hairs present, each hair basally bulbous, then gradually tapers apically.

This species is unique among Stictoponera in having hairs on the scape that have a bulbous base and gradually taper toward the apex. These specialized hairs are only found on the scapes and not elsewhere on the ant.

Type Material

Holotype worker. Philippine Islands, Misamis Oriental, Minubanan, 1050-1200m, 5/9-iv-1961, H. Torrevillas. Deposited in Los Angeles County Museum of Natural History.


The species epithet is a compound name derived from the Latin words for a fleshy underground stem or bulb, bulbus, and for hair, pilus (m). It alludes to the uniquely shaped hairs on the scapes.
