Genus: Pseudocorticus

• Description: Antennae 10-segmented with a distinct, 1-segmented club composed of 2 connate segments. Antennal setation dense, covered in short, flattened, scale-like setae at base and thin, hair-like setae for terminal segments. Subantennal grooves absent. Eyes well-developed, round, coarsely faceted and densely setose. Pronotal disc with pair of median tubercles. Pronotal lateral margins widest anteriorly, distinctly explanate. Procoxal cavities open. Metacoxae narrowly separated, separation less than metacoxal length. Tarsal formula 4-4-4. Dorsal surface sparsely covered with short, scale-like, light and dark colored setae.

• Similar genera: The genus Pseudocorticus superficially resembles the genera Rhagodera and Namunaria. The distinctly carinate elytra and weak, 3-segmented antennal club serve to distinguish Rhagodera. The lack of scale-like setae on the antennae, presence of antennal grooves, a distinctly 2-segmented antennal club, and closed procoxal cavities and serve to distinguish Namunaria.

• 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 club segments are often difficult to count due to dense, scale-like setae. The antennae 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.
