Characteristics

Characteristic to Histeroidea are an accessory posterior ridge (locking device) behind the hind margin and presence of medial loop and apical hinge of wing. Elytra truncate, 1 ot 2 abdominal segments visible, abdominal 8th segment completely invaginated in the 7th segment. Antennae have 8 (seldom 7) segments preceding a club of fused segments. Ventral body surface glabrous.^[1]
