Adults reach a length of about 12 mm. They are shiny black, the
elytra with a bronze-green or purple shimmer. The frons is rather sparsely punctate and very slightly flattened. The
pronotum is moderately densely covered with fine punctures. The scutellum is almost smooth. The elytra are finely leathery and wrinkled, the punctures on them are not densely spaced, the ribs are only marked by the limiting rows of punctures and are punctate, as are the spaces between them. The punctures have extremely tiny
setae. == References ==
