Genus: Phloeonemus

• Description: 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, as long as eyes. Eyes large, 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. Procoxal cavities open. Metacoxae narrowly separated, separation less than metacoxal length. Elytra carinate, with two rows of punctures between carinae. Tarsal formula 4-4-4. Dorsal surface glabrous.

• Similar genus/genera: The genus Phloeonemus is superficially similar in general appearance to Denophloeus and Acolobicus but is immediately distinguished by the deeply emarginate eyes.
