This small, elongate-cylindrical beetle is about 1.8 to 2.0 mm long. This weevil can be identified by the declivital face with interstriae 2 which is unarmed by tubercles. Elytral apex is attenuate, with three pairs of large flattened tubercles. The declivital interstriae is flat, and the interstriae 2 is not impressed.[3][4]
A polyphagous species, it is found from many host plants.[1][5]
