Eurypleura bicornis is a large Southeast Asian tessaratomid bug. The expanded front corners of the pronotum form a matched pair of horn-like projections, producing one of the most dramatic silhouettes among true bugs.

What makes this species remarkable?
Bicornis means “two-horned”: the huge lateral points are extensions of the pronotum, not separate horns attached to the head.
The original nineteenth-century description gives a body length of about 35 millimetres — enormous for a terrestrial true bug.
Its broad shield, powerful shoulders and plant-piercing beak combine beetle-like armour with the feeding machinery of a true bug.
