| Gnamptogenys pittieri|
Hypogeic leaf litter (including bamboo) dweller of cloud forests of the Venezuelan Cordillera de la Costa.
A member of the strigata complex (in the strigata subgroup of the striatula species group). Sculpture with rough aspect; frontal lobes each with a median emargination; eyes protuberant and subglobular; propodeal spiracles rnounted at the apex of protuberances. A series from near Tejerias differs from the type series in having the notch on the frontal lobes shallower, the propodeal spiracles on higher turrets, finer costulae on the anterior postpetiolar face and metacoxal spines more acute.

Not much is known about the the biology of Gnamptogenys pittieri. 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.
