Redescription. male: Body 12.5−17.5 mm long and 2.5−3.0 mm wide, predominantly yellowish-brown to reddishbrown, except apex of mandibles dark brown and compound eyes black, and antennae with dark brown and slightly paler flagellum. Entire body and appendages clothed with short golden pubescence; presence of scattered dark hairs on undersides of basal antennomeres, and some erect yellow hairs on pronotum and elytra. Head, pronotal disc, metepisternum and sides of abdominal segments finely and densely punctured. Elytra with basal half of disc bearing six longitudinal rows of coarse and deep punctures, latter becoming gradually finer and disorganized towards apex.

Head nearly as long as wide, slightly wider than prothorax, with surface finely and densely punctured. eyes very large, with inferior lobes 3 times longer than genae; depression between base of antennae and head with a medial groove. Antennae approximately as long as body; third antennomere longest, longer than scape and fourth, latter becoming shorter.

Pronotum in dorsal view about as long as wide, slightly constricted basally and apically; apical and basal margins shallowly emarginate in middle; central disc slightly raised. Scutellum trapezoidal, with posterior margin shallowly emarginate in middle. elytra approximately 4.3 times longer than combined humeral width, and 3.0 times longer than head and pronotum combined, in dorsal view slightly constricted on basal third; apex obliquely truncate with acute sutural and marginal angles. Posterior legs with femora reaching level of posterior edge of abdominal ventrite iv and tibiae approximately 2 times as long as tarsi.

Abdominal ventrite vii with shallow medial depression extended on entire length.

Male genitalia: Tergite VIII densely clothed with short hairs, transverse, apex truncated and shallowly emarginate, broadly ( Fig. 6 a). Tegmen curved in lateral view, lateral lobes elongate with round apex, dorsal surface mostly covered with long setae; base of each lateral lobe transversely and obliquely ridged ventrally, those ridges densely furnished with fine hairs ( Fig. 6 b–e). Median lobe 0.8 times as long as tegmen and curved in lateral view; median struts 0.6 times as long as median lobe; ventral plate with apex rounded, and median foramen rounded ( Fig. 6 f); endophallus with 2 pairs of slender subapical sclerites, both very slender, baculiform and long pair 1.2 times as long as short one ( Fig. 6 g).

Female: Body 13.0–17.0 mm long and 2.5–3.0 mm wide. Frons wider than that of male. inferior lobes of eyes 1.5 times as long as genae. Abdominal ventrite vii with a narrow medial groove.

Remarks. A careful examination of the type specimens shows that O. hanoiensis Pic ( Fig. 5 ) is a junior synonym of O. fuscipennis ( Fig. 1).
