Found in leaf litter and earth samples from humid forests.

Identification

A member of the haytiana complex (in the strigata subgroup of the striatula species group). Mandibular dorsum smooth and shining and apex of scapes surpassing the vertexal margin; declivitous propodeal face flat and separated from the dorsal face by a sharp angle; propodeal spiracles elevated at the apex of cylindrical tubercles. A series from near Kavanayen show very sharply defined costulate with fine vermiculation in contrast with the glazed and effaced aspect of other series. (Lattke 1995)

Biology

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