Genus: Denophloeus

• Description: Body larger (6-7mm), elongate, somewhat cylindrical. Surfaces opaque, very dark in color (dark brown to black). Antennae 11-segmented with a 2-segmented club (club may appear 3-segmented due to slightly enlarged antennomere 9). Antennal setation sparse. Subantennal grooves present, wide, longer than eyes. Eyes small, round, well-developed, finely faceted. Eyes deeply emarginate anteriorly by projection of frons, forming a distinct canthus. Pronotal disc convex, with a pattern of sinuate carinae. Pronotal lateral margins widest anteriorly, distinctly explanate. Procoxal cavities open. Metacoxae narrowly separated, separation less than metacoxal length. Elytra with irregularly shaped, blunt carinae and several small tubercles near apical declivity. Tarsal formula 4-4-4. Dorsal surface sparsely pubescent, composed of short, curved, thin setae. Body usually encrusted with dirt or debris.

• Similar genera: The genus Denophloeus is superficially similar in general appearance to Phloeonemus and Acolobicus but is immediately distinguished by the larger body size, sculpturing of the pronotum and elytra, and distribution.
