Belongs within: Scolytinae.

Scolytus is a genus of phloeophagous beetles found in Eurasia, northern Africa and the Americas. The greater number of species are monogamous with a smaller number of bigynous species, mostly found in the Neotropics (Wood 1986).

Characters (from Wood 1986): Eye oval, entire; antenna with funicle 7-segmented, club rather large, flattened; pronotum unarmed, lateral margins costate; scutellum depressed, subtriangular, apically (posteriorly) pointed; elytral bases depressed in scutellar area, appearing emarginate in median area; costal margin of elytra normal (straight) and overlapping metepisternum; protibia unarmed on lateral margin, outer apical angle extending into spine curving toward and exceeding inner apical angle, socketed denticles never present; metapleural suture descending subvertically to groove receiving groove on costal margin of elytra then turning abruptly and continuing parallel to groove to near metacoxal process; abdomen flexed upward from anterior margin of segment 2.
