Adapted from Wood 1982, p. 667-705


Species within the genus Ips are distinguished from Orthotomicus Ferrari and Pseudips Cognato by the flat club with bisinuate sutures (except from Orthotomicus latidens and spinifer).


Species in this genus range from 2.1 to 6.9 mm in length and are approximately 2.4 to 2.8 times as long as wide. Their color ranges from yellowish brown to almost black. The pronotum is as long as wide and asperate anteriorly. The scutellum is large and flushed with the elytra. The declivity is concave, with the lateral margins bearing spines, the third always being the largest and often capitate. The vestiture consists of long and erect hair-like setae. The anterior margin of the compound eye is emarginated. The scape is longer than the 5-segmented funicle. The club is oval to near circular, strongly flattened, with two bisinuate sutures on the anterior face. The procoxae are contiguous.
