Gnamptogenys regularis

J. Longino (pers. comm.) reports observing a short linear column of workers walk to an apparent nest entrance on the ground. He excavated it before any activity had begun and found a small colony of Pseudomyrmex boopis. The related Gnamptogenys horni has a dietary preference for ants and beetles (Lattke, 1990). One specimen was removed from the stomach of a Tamandua tetradactylus.

Identification
Declivitous propodeal face abruptly separated from dorsal face, superolaterally with small angulate lobes; metacoxal tooth apically rounded and not triangular; dark brown body, testaceous legs. Transverse costulation can be totally absent or occupy all of the anterior nodal face. Females tend to have the anterior nodal face to tally transversely costulate. (Lattke 1995)
