Millipede feeder captured in litter samples from wet forest. Some specimens found in stomach contents of Dendrobates histronicus.

Identification

A member of the rastrata complex (in the rastrata subgroup of the rastrata species group). Promesonotal suture and metanotal groove impressed but not breaking sculpture; propodeal spiracle opening large and round, right behind teeth; me tacoxal teeth long and sharp; occipital carinae wide and visible in frontal view; anterior clypeal lamella laterally rounded and anteriorly straight to very broadly convex. The cephalic sculpture can vary from evenly costulate to roughly rugose and the petiole length vs. width is also variable. (Lattke 1995)

Biology

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