couplet 1 of 4
Labrum fused to clypeus and not visible externally.
Tarsomere 4 relatively long, not concealed by lobe on tarsomere 3.
Antennal insertions (antennal foramina) lateral and not visible from above.
Lateral pronotal carinae entire and simple.
. . . . . . Parandrinae
- Labrum separate from clypeus and visible externally.
Tarsomere 4 very short and concealed by lobe on tarsomere 3.
Antennal insertions (antennal foramina) variable but they are clearly visible from above.
Lateral pronotal carinae absent, incomplete or complete.
