MATERIAL EXAMINED. 1♂, 1♀: Vietnam: [I.R.Sc. N.B/ Vietnam: Tam Dao N.P., 21.31 N / 105.33 E; 25- 30.VII.2011, Malaise trap, leg. J. Constant & J. Bresseel, I.G. 31.933 GTI project]( RBINS); 1♀: ibid ( MNHN) .

DIAGNOSIS. It is close to O. carinatus Tian & Deuve, 2013 , but eyes distinctly larger, labrum straight at frontal margin (convex in the latter); lateral expanded margin of pronotum much wider near base than front; inner angle of elytra finely denticulate; and middle tibiae slightly expanded medially instead of thin and curved medially (as in O. carinatus ).

Length of male: 14.5 mm; habitus of male as in Fig.19 .

Male genitalia ( Figs 20–21 ): median lobe of aedeagus stout, bisinuate ventrally, gently arcuate at apical 1/3, evidently expanded in middle portion; dorsal opening large, gently and gradually narrowed from subapex towards apex, broadly obtuse at apex; in dorsal view, apical lamella thin, longer than wide, gradually narrowed towards apex which is blunt.

SEXUAL DIMORPHISM. Male smaller than female; labrum straight at frontal margin (convex in female); densely punctate on head, and also on pronutum and elytra (only on head in female); middle tibiae slightly expanded medially in male.

DISTRIBUTION. Northern Vietnam.
