What makes this species remarkable?
Its scientific trail begins with the vague type locality “Florida”; modern catalogue work narrowed that historic point to Cedar Key, anchoring a 170-year-old name to one precise Gulf-coast landscape.
A female photographed at a coastal salt marsh came to ultraviolet light and immediately crushed another beetle, manipulating the prey with mouthparts while the mandibles reduced it to fragments.
The female pronotum bears a specialised mating-coupling groove that receives the male mandible, while expanded adhesive pads on the male forelegs help lock the pair together on exposed ground.
