Beaverium can be distinguished by the elytral declivity distinctly flattened and posterolaterally broadened; posterolateral declivital costa terminating at interstriae 5; pronotal disc punctatepronotum anterior margin with continuously elevated carinascutellum flat, flush with elytramycangial tufts absent,;and procoxae contiguous.

Gallery system

This appears to have been described only in B. insulindicus (Eggers), a species not found in the study region. Based on observations in Fiji, Roberts (1977) notes a short radial gallery, penetrating 2–4 cm, with several longitudinal galleries parallel to the stem axis, all in the same plane, and without enlarged brood chambers.
