In addition, the combination of the following characters is diagnostic: antennae reaching base of prothorax, with second funicular article scarcely longer than first; widened frontal groove; pronotum as wide as long, granulate; elytra triangularly shaped; tibiae not crenulated or dentate within; scutellum protruding; and aedeagal apex slightly acute.
