Nothing is known about the biology of Gnamptogenys nana. Its nearest relatives, Gnamptogenys horni and Gnamptogenys regularis include beetles as a significant part of their diets, while horni also preys on ants.


A member of the regularis complex (in the regularis subgroup of the mordax species group). Head subquadrate, mandibles subtriangular with striae at base, clypeal lamella straight, no transverse mesosomal impressions, propodeal declivity with vertical costulae. (Lattke 1995)

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