Diagnosis: Female 3.0– 3.5 mm long; derm fuscorufous; female with rostrum longer than body, male with rostrum not as long as body, abruptly emerging from frons, not as broad as frons at base; prosternum with process separating procoxae, pronotum with median vittae of golden clavate scales flanked by shorter lateral vittae with two lateral macula at anterior margin, scutellum moderate sized clothed with golden scales; elytra with vittae on intervals 1–2 extending from scutellum to midpoint, two macula past midpoint straddling intervals 2–3 of golden scales, crosshatch setae long and piceous; legs long and willowy, metafemur exceeds apex of elytra, tooth small, tibiae straight, female without uncus or murco, male with long inner bifid process extending well beyond tibial apex on metatibia; venter essentially glabrous except for lateral golden macula on ventrite 2.

Differental diagnosis: This species is very close to Curculio nobilior (Heller) and perhaps conspecific with this species as it also occurs on Borneo as well Sumatra and Banguey Heller (1927). It is distinguished from all other Curculionini by the prosternal process separating the procoxae.

Distribution: Only found on Malaysian Borneo.
