Imaging technique: 

A groove, impression, or excavation in the side of the head, which runs above or below the eye to accommodate at least the antennal scape, but often the entire antenna when folded back. Antennal scrobes vary in development from simple broad shallow grooves to extensive deep trenches. Distinguishes among myrmicine genera.
