| Gnamptogenys bisulca|
Kempf & Brown, 1968
Occurs in mesic forested habitats. The localities suggest preference for relatively cool sites as the lowest altitudes are found at higher latitudes (10°N) and as latitude approaches the equator the localities ascend in altitude. (Lattke 1995)
A member of the strigata complex (in the strigata subgroup of the striatula species group). Longitudinal costulae on propodeal declivity, metacoxal spines hooked and triangular, not acicular; well defined transverse costulae on postpetiolar sternum; propodeal spiracle as low as surrounding sculpture, not raised. Within the strigata complex this species is unique due to the development of its metanotal groove, and within the striatula group two other species also show this character state. (Lattke 1995)

Not much is known about the the biology of Gnamptogenys bisulca. We can speculate that the biology of this species is similar to other species of the genus. Gnamptogenys are predatory ponerine ants that inhabit tropical and subtropical mesic forests. Nesting is typically at ground level in rotten wood or leaf litter. Some exceptions include species that are arboreal, a dry forest species and species that nests in sandy savannahs. Colony size tends to be, at most, in the hundreds. Queens are the reproductives in most species. Worker reproduction is known from a few species in Southeastern Asia. Generalist predation is the primary foraging/dietary strategy. Specialization on specific groups (millipedes, beetles, other ants) has developed in a few species.
