Until recently included with Ips DeGeer, it can be distinguished from the 3-spined Ips by having the third and largest spine straight and cylindrical as well as strongly procurved club sutures that are never bisinuate.


Species in this genus range from 3.5 to 5.0 mm in length and are approximately 2.5 times as long as wide. Their color varies from light brown to dark reddish brown. The pronotum is as long as wide, and its anterior half is asperate. The scutellum is small. The declivity is concave, the lateral margins armed with 3 pairs of spines, the third spine being the largest and cylindrical. The vestiture consists of long erect hair-like setae. The anterior margin of the compound eye is emarginate. The scape is longer than the 5-segmented funicle. The club is oval with two strongly procurved sutures. The procoxae are contiguous.
