Stictoponera bulbopila

Nothing is known about the biology of this species.

Identification
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 Gnamptogenys 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.

Etymology
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.
