Gulo-mental: includes the region covered by the gulag and mentum.
But the -mentum is a mere termination, and has nothing to do with mens at all.
The mentum carries at its extremity a pair of lobes with sharp fangs.

Our Mentum may generally be known by its situation between the hinges and base of the Maxill.
Anthobian: feeding on flowers; applied to certain lamellicorn Coleoptera in which the labium extends beyond the mentum.
Buccal fissure: the mouth slit or opening: the opening on each side of the mentum.

Submental peduncle: in Coleoptera, the prolonged portion of the gula supporting the mentum.
