Gnamptogenys haenschi

This species inhabitats forest and apparently nests in rotten wood as well as in soil. It has also been taken in oil palm plantations. Some specimens were collected from carrion traps baited with iguana meat. Longino (pers. comm.) reports finding a nest beneath a rotten log; the ants burrowed into the soil on exposure. (Lattke 1995)
