Antennaeantennae:
paired, segmental appendages, borne one on each side of head, functioning as sense organs and bearing a large number of sensilla.
10-segmented with a distinct, 1-segmented club composed of 2 connateconnate:
united at base, or along the entire length; fused.
segments. Antennal setation dense, covered in short, flattened, scale-like setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.
at base and thin, hair-like setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.
for terminal segments. Subantennal groovessubantennal groove:
groove or concavity lying below the antennal insertion and housing the base of the antenna. Placed between the eye (if present) and the mandibular articulation, and sometimes extends below or behind the eye.
absent. Eyes well-developed, round, coarsely faceted and densely setose. Pronotal discpronotal disc:
the area of the pronotum which is visible dorsally and usually delimited laterally by the two lateral carinae. Contrasted with the paired pronotal hypomera, which extend onto the ventral surface.
with pair of median tuberclestubercle:
a small knoblike or rounded protuberance.
. Pronotal lateral margins widest anteriorly, distinctly explanateexplanate:
spread out and flattened; applied to a margin.
. Procoxal cavitiesprocoxal cavities:
external closure: Externally closed when the postcoxal processes of the hypomera meet the prosternal process or meet one another.
open. Metacoxaemetacoxae:
the coxae of the metathorax.
narrowly separated, separation less than metacoxal length. Tarsal formulatarsal formula:
the number of tarsomeres on the fore, mid, and hind tarsi, respectively.
4–4–4. Dorsal surface sparsely covered with short, scale-like, light and dark colored setaeseta:
a sclerotized, hairlike (or scalelike) projection of cuticula arising from a single trichogen cell and surrounded at the base by a small cuticular ring.

The genus Pseudocorticus superficially resembles the genera Rhagodera and Namunaria. The distinctly carinate elytra and weak, 3-segmented antennal clubantennal club:
an enlarged portion of the antennal apex, consisting of a variable number of antennomeres (often 3). In an incrassate, antenna the antennomeres gradually enlarge towards to apex, but if there is an abrupt change in length or width at some point, then the antennomeres beyond this are considered to be part of the club.
serve to distinguish Rhagodera. The lack of scale-like setae on the antennaeantennae:

Pseudocorticus blairi Hinton, 1935
South Central (TX), Southwestern (NM) USA.
Likely occurs in Southwestern (AZ) USA.
Members of this genus have been found under the bark of dead hackberry (Celtis reticulata) and oak (Quercus muhlenbergii).
Abundance: Rare.
Antennal segments and antennal clubantennal club:
an enlarged portion of the antennal apex, consisting of a variable number of antennomeres (often 3). In an incrassate, antenna the antennomeres gradually enlarge towards to apex, but if there is an abrupt change in length or width at some point, then the antennomeres beyond this are considered to be part of the club.
segments are often difficult to count due to dense, scale-like setae. The antennaeantennae:
paired, segmental appendages, borne one on each side of head, functioning as sense organs and bearing a large number of sensilla.
appears to be 10-segmented with a one-segmented club composed of apparently 2 fused (connate) segments, denoted by an annulation, or 11-segmented with a composite, 2-segmented club.
