Its morphology puts it in the rastrata group of millipede hunters. (Lattke 1995)

Identification
A member of the rastrata complex (in the rastrata subgroup of the rastrata species group). Relatively small eyes; clypeal lamella medianly concave; Promesonotal suture vestigial and small denticles on the propodeum; node elongate, with transverse costulate. Kempf (1968:377) reports a series with transverse costulate on the anterior pronotal face, differing from the longitudinal sculpture of the type series. (Lattke 1995)

Biology
Not much is known about the the biology of Gnamptogenys lanei. 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.
