What makes this species remarkable?
The dorsal surface is an almost continuous lacquered green, but the underside and terminal abdominal plate can flash copper-red when the beetle turns or takes flight.
The outer rear corners of the elytra are expanded, giving the otherwise oval beetle a sharply truncated, almost shield-like posterior profile.
Its compact antennal club unfolds into multiple thin sensory leaves, allowing a small structure to become a broad chemical-detection array in seconds.
