Sifted from leaf litter in rain forests.
A member of the haytiana complex (in the strigata subgroup of the striatula species group). The degree of effacement of sculpture, and size can vary considerably. Mandibles, vertex and anterior petiolar face smooth and shining, occiput sometimes with very faint transverse costulae; last 3 antennal segments form vague club; declivitous propodeal face with transverse costulae, propodeal spiracles elevated above rest of cuticle; pronotal suture present but fine, metanotal suture well impressed, breaking sculpture; no anterolateral lobes on declivitous propodeal face; metacoxal spine present.

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