Identification
They resemble Cerambycinae in having the terminal segment of the maxillary palps blunt or truncate at the apex. They differ from them in having the coxae conical and the bases of the antennae are usually not surrounded by the eyes. Many Lepturinae have the elytra tapering posteriorly and/or the pronotum narrower than the base of the elytra, giving them a rather broad shouldered appearance.
They differ from flat faced longhorns (Lamiinae) in that their face slants forward or is nearly vertical.
