The labrum is broad and shield-shaped, folding back up over the smaller mouthparts when retracted, and often bearing den- ticles near its base, presumably to help in holding prey. The palpi are short, with segmentation ranging from 5, 3 downward, normally the same in both worker and female (with some ex- ceptions)..
