Lasius pogonogynus

This ant nests under stones. Dealate females were collected loose on the ground during June and July, and early August. Flights occurred from June to July. In New Mexico, nests have been found in a range of habitats, from residential areas to meadows and deciduous forests. (Mackay and Mackay 2002)

The apex of the petiole is blunt (when viewed in profile) and convex or straight as seen from the front (rarely slightly concave).
