Diagnosis. Species of Entimus are easily identified by their large size (12– 45 mm) and the presence of green, blue, and gold iridescent scales. 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.
