Gnamptogenys

Gnamptogenys forms small colonies with less than 100 workers in rotten logs on the ground. Workers are general predators on arthropods and forage in leaf litter.



Worker of G. biroi from Queensland.

Identification
The forward sections of the frontal lobes and the antennal sockets are separated by the broadly rounded or triangular rearward extension of the clypeus. When viewed from above, the pronotum and mesonotum form a single, uninterrupted plate. The first segment (coxa) of the hind leg has a tooth or spine on its upper surface near the body. The node of the petiole has distinct front, top and rear faces.

While these ants share many features with Heteroponera and Rhytidoponera, the fused pronotum and mesonotum and the spine on the coxa of the hind leg (near the body) are unique and will separate these ants from all others.
