Identification
Clytus planifrons can be distinguished from related Clytus by its flattened (forehead), which is the source of its specific epithet "planifrons" (flat-fronted). The species exhibits the typical Clytus pattern of yellow and black banding on the . It can be separated from the similar Clytus ruricola by differences in antennal length and the precise configuration of elytral markings. The pronotum lacks the strong spines or projections found in some other cerambycid .
