Notes.

One of the few species of the genus restricted to conifers. Distinguished from other Xyleborus by the steep declivity which occupies the apical ¼ of the elytra, and broadly rounded posterolateral margin of the declivity. It is distinguished from X. pubescens by the larger declivital denticles and smaller, deeply impressed declivital strial punctures.
