Aphaenogaster mexicana

Identification
Aphaenogaster mexicana is rarely collected, but can be distinguished from other species in North America due to the head being narrowed posteriorly into a neck with a collar. The antennal scapes pass the occipital margin by one-half the length of the scape. (DeMarco, 2015)
