Cucujus clavipes Fabricius 1777
The only species in the genus in North America.
Adult 10-14 mm

Adult: bright red above; dull red below. Antennae extend to the base of the pronotum. Three elevated ridges on the pronotum. Pronotum coarsely punctate; elytra finely punctate.(1) - contributed by Stephen Cresswell
