Adapted from Cognato, A, I. 2000, p. 362–366

Diagnosis

Until recently included with Ips DeGeer, it can be distinguished from the 3-spined Ips by having the third and largest spinespine:
a stiff, pointed, tapered process on the surface of the integument, usually long
straight and cylindrical as well as strongly procurvedprocurved:
pertaining to structure (antennae, setae) which is basally perpendicular to the body and whose apical part is curved anteriorly
clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
sutures that are never bisinuatebisinuate:
displaying two sinuations
.

Description

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 pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is as long as wide, and its anterior half is asperateasperate:
of a surface or texture which is rough
. The scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
is small. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is concave, the lateral margins armedarmed:
having a sclerotized surface structure, giving a rough texture; may serve as defense
with 3 pairs of spines, the third spinespine:
a stiff, pointed, tapered process on the surface of the integument, usually long
being the largest and cylindrical. The vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
consists of long erect hair-like setaehair-like setae:
setae that are thin and similar to a hair
. The anterior margin of the compound eye is emarginateemarginate:
notched or indented
. The scapescape:
the first and basal segment of the insect's antennae
is longer than the 5-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
. The clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
is oval with two strongly procurvedprocurved:
pertaining to structure (antennae, setae) which is basally perpendicular to the body and whose apical part is curved anteriorly
sutures. The procoxaeprocoxae:
extra segment occasionally preceding coxa (hip joint) of the first or anterior pair of legs of arthropods
are contiguouscontiguous:
sharing an edge or boundary; touching
.
