Colour dark metallic green, shiny, underside piceous; labrum, palpi, antennae, marginal channel of prothorax, a pattern on elytra, and legs testaceous. The marginal channel of the elytra is testaceous throughout (rarely interrupted at middle). Head moderately convex, closely punctate, more sparsely on middle of front, clypeus bisetose, a few punctures at its base, suture rounded, mentum uneven and pitted, lobes rounded, epilobes projecting. Prothorax very wide, moderately convex, trans-versely depressed in front of base, moderately and rather closely punctate, sides gently and evenly rounded, with fairly wide, smooth, refiexed margin, hind angles right, median line obsolete. Elytra oval, convex, base unbordered, sides hardly widened behind shoulder, with refiexed border a little narrower than that of prothorax; 15-striate-punctate, intervals quite flat and very smooth, no microsculpture. The elytral pattern is as presented in Fig. 2.5 . Comparisons: The pattern on the elytra of O. oberthueri Gestro is similar to that of O. piceopictum Wrase , but O. oberthueri is much smaller in size, it has denser and coarser puncturation on the pronotum and deeper elytral striae.
