- Description: Antennae 11-segmented with a 2-segmented club. Antennal setation sparse. Subantennal grooves present, short, not reaching past eyes. Eyes round, well-developed, finely faceted. Eyes deeply emarginate anteriorly by projection of frons, forming a distinct canthus. Pronotal disc convex, without distinguishing sculpture. Pronotal lateral margins widest at middle, distinctly explanate, finely serrate. Procoxal cavities closed. Metacoxae narrowly separated, separation less than metacoxal length. Tarsal formula 4-4-4. Dorsal surface with patches of dark and pale, flattened, curved setae.
- Similar genera: The genus Namunaria is superficially similar in general appearance to Pseudocorticus. Pseudocorticus can be readily distinguished by the open procoxal cavities, antennae covered in dense, short, scale-like setae, antennal club one-segmented, lack of antennal grooves on head, and dorsum covered in short, scale-like setae.
