Specimen Labels

Rarely collected, known from leaf-litter samples of humid forests.

Identification

A member of the haytiana complex (in the strigata subgroup of the striatula species group). Head in frontal view with concave vertexal margin, vertex smooth and shining; anterior face of postpetiole and median disc of gastric tergum II smooth and shining; metacoxal spine absent and declivitous face of propodeum with small superolateral lobes, spiracles lateral and not elevated; metanotal suture absent. Nearest relative is apparently Gnamptogenys relicta. (Lattke 1995)

Biology

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