Adapted from Wood 1982, p. 141-142

Diagnosis

Within the Tomicina, Hylurgopinus can be distinguished from the similar Xylechinus Chapuis by its 7-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
.

Description

This monospecificmonospecific:
a genus that only contains one known species
genus ranges from 2.2 to 2.5 mm in length and is approximately 2.3 times as long as wide. The color is dark brown. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is wider than long. 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 convex with small granulesgranules:
a small grain-like elevation
. The vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
consists of abundant scale-like setaescale-like setae:
setae that are wider than hair
and rows of erect bristles in the elytraelytra:
the two external and hardened or sclerotized forewings of adult Coleoptera, often appearing leather-like in texture
and declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
alike. The anterior margin of the compound eye is entire. The scapescape:
the first and basal segment of the insect's antennae
is usually as long as its 7-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
. The ovateovate:
egg shaped, with the narrow end apically
clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
has three straight suturessutures:
a seam or seam-like line of contact between two sclerites or hardened body parts immovably connected
. The procoxaeprocoxae:
extra segment occasionally preceding coxa (hip joint) of the first or anterior pair of legs of arthropods
are widely separated.

Distribution

The sole and endemic species Hylorgupinus rufipes occurs east of the Rocky Mountains in temperate North America.
