Specimen Label

Kempf (1970) notes a nest preference for pre-existing cavities in plants. It is also a frequent forager on trees and shrubs. Usually found in lowland to premontane humid forests.

Identification

A member of the porcata subgroup (in the striatula species group). Pronotum with concentric costulae; mesonotum with longitudinal costulae, sometimes surrounded by concentric costulae; anterior postpetiolar face with 3-4 transverse costulae and dorsal face with longitudinal costulae; metacoxal tooth acicular. Body dark brown, legs brown. An occasional specimens may have vertical costulation on the dec1ivitous propodeal face, as in Gnamptogenys striatula, but the backwards tilt of the petiolar node and its brief anterior peduncle will identify pleuradon. (Lattke 1995)

Biology

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