A very small weevil of about 3.5 mm length. It is pale brown (sometimes slightly reddish) with a few paler whitish markings. Orange-brown legs, brown body. Angular rear, patch of warts on rear of each wing-case. Erect oval scales on wing-cases. Rather large pronotum. Patterns of scales when fresh, but in many individuals these have worn away. One of our commonest weevils.
