Adults reach a length of about 9.7–13 mm. They have a pitch black head. The pronotum is lustrous, translucent, with a broad irregular black band from the anterior to the posterior margin, wider posteriorly and narrower near middle. The background is bright yellow to light orange with well-defined diagonal orange and brown patches laterally. The scutellum and elytra are pitch black, slightly lustrous. There is a large whitish to pale yellow roundspot at mid-length of each elytron, nearly reaching the lateral borders but not meeting at the suture. The thorax, legs and abdomen are pitch black.
Etymology
The species is named in honour of the late Professor Sergio A. Vanin in appreciation of his enormous and enduringcontribution in the study and teaching of zoology, especially Coleoptera systematics.
