Redescription. Body slender, elongate, dark brown, larger than O. anogeissi and O. bilobus , ornamented with various spots and patches of pale whitish pubescence ( Fig. 1A ); vertex with longitudinal band of pale whitish pubescence, starting between antennal tubercles and obliquely running downwards along inner margin of eyes ( Fig. 1E ); frons densely pubescent with white setae ( Fig. 1F ); antenna 11-segmented ( Fig. 1A ), granulations on antennomere I dense and coarse in male ( Fig. 2B ), very sparse basally and extending slightly more towards apex in female ( Fig. 2C ), antennomere III almost 2 times longer than antennomere IV ( Fig. 1G ); elytral surface densely punctate, punctation gradually finer towards apex, ornamented with various large and small pale whitish patches, 1 semioval, elongate, close behind scutellum on either side of and close to suture, a series of small spots along the suture behind postscutellar patch and extending to tip of elytra ( Fig. 1D ), in some specimens these spots are continuous ( Fig. 2A ), second series of small spots forming a short line before middle and including 2 or 3 small spots near middle, third series of 2 pairs of large spots laterally on disc – 1 before middle and 1 after and including a small spot at base and 3 spots near apex, fourth series of elongate spots on extreme lateral margin;, elytral apex rounded ( Fig. 1D ); continuous band of broad, white pubescence along lateral margin of thoracic and abdominal sterna, interrupted by dark, rounded areas without pubescence on each abdominal segment ( Fig. 1B, C ), last abdominal segment of female longer than that of male; mesocoxal cavities closed, mesosternal process broad ( Fig. 1C ); legs elongate, tarsal claws diverging by more than 90° ( Fig. 1H ). Median lobe longer than median struts ( Fig. 3A, B ), medial part larger and longer than tegmen. Apex of median lobe almost rounded, smooth throughout ( Fig. 3C ). Ring portion of tegmen long, converging, tip extended and pointed ( Fig. 3A ), lobes of parameres very close, base almost united, tip sparsely covered with long setae, ( Fig. 3C ). Endophallus elongate, attached between bifurcated parts of median lobe ( Fig. 3A, B ).
