The pronotum is distinctly elongated with long paired serrations along the anterior edge and emarginate sides.

Instead, the female seeks out the newly excavated gallery of another ambrosia beetle, often a Dryocetoides species, enters it, and consumes the original occupant.

[2] Taxonomy[3] Detailed Description: Eyes are shallowly emarginated, with the upper portion smaller than the lower.

The anterior edge of the pronotum features two distinct flat denticles protruding anteriad, and the entire margin extends forward, forming a noticeable "hood" over the head.

The pronotal disc is shiny or smoothly alutaceous, with small punctures, while the lateral edge is obliquely costate.

The bases of the elytra are straight with an oblique edge, and the elytral disc is longer than the declivity, being convex or bulging.

The dorsal profile of the elytral apex is prolonged, appearing attenuated, angulate, or concave, and emarginate.

The posterolateral declivital costa is elevated, reaching beyond the fifth interstriae and often completely surrounding the entire declivity.
