Identification
A combination of characters usually distinguishes Cerambycinae from other subfamilies of Cerambycidae:
  • last segment of the maxillary palp blunt
  • face held slanting forward or nearly vertical
  • pronotum rounded and widest near the middle
Some groups have spines on apices (tips) of elytra. Members of the tribe Elaphidini have antennae with prominent spines.
