The Mesoptillinae are weevils whose larvae bore in wood or in stems of herbaceous plants (Anderson 2002).

Characters (from Anderson 2002): Mouthparts with labial palpi of three distinct articles, elongate, not telescoping, dorsally situated at apex of prementum; pronotum only slightly narrower than base of elytra; elytra with basal margin from intervals 2–4 extended anteriorly, overlapping base of pronotum; large hook-like apical tooth on hind tibia, larger than tarsal claw.
