The pronotum has a bronze-like metallic lustre, and has a small spike at the back corner, in this species it is almost without hair except as a brim along the edge.

The head is relatively small, the antennae have a long, thin shaft but no striking fan.

These beetles live in the Valdivian temperate forests along the west side of the Andes.

The adult beetles move around a lot up in tall trees, where the males fight for the females with the help of their long jaws.

The males' jaws probably prevent them from eating, most likely the females do not feed themselves as adults either.
