Adults reach a length of about 11 mm. They are lighter or darkerbrown, with the head sometimes blackish. The head is coarsely punctate, the punctures with brown setae. The antennae are yellowish-brown. The pronotum is dull and has punctures that are rather widely spaced and partly weak, partly strong. The stronger punctures, which are mainly located behind the anteriormargin and next to the lateral margins, are covered with yellow hairs. The elytra are quite densely punctured and there are bristle-like yellow hairs arranged in rows, particularly along the lateral margins.
