Gnamptogenys annulata (Mayr, 1887) Specimen Label

J. Longino (pers. comm.) reports from a nest midden chitinous fragments of Coleoptera, aradid bug nymphs, an unidentified male ant, and a Camponotus worker. An apparently recently killed Pheidole (cephalica?) queen was also found in a nest chamber. (Lattke 1995)

Identification

A member of the annulata complex (in the regularis subgroup of the mordax species group). Finely striate species; longitudinal striae on head, promesonotum and gastric segments 2 and 3; petiolar dorsum with transversely arched striae; mandibles subtriangular; metacoxal spine absent; body reddish brown; coxae ferruginous yellow; tibiae and femora yellow to testaceous but apically ferruginous yellow to ferruginous. The gauge of costulation can vary from striate to finely costulate, but coloration is fairly stable.(Lattke 1995)

Biology

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