Redescription. Head blackish; pronotum and abdomen dark brown; elytra pale yellow, but inner and posterior margins darker. Mandibles, maxillary palpi, first 4 antennomeres, and legs light yellow. Length [average] male, 3.7 mm; female, 4.0 mm.

Male. Head ( Fig. 16A) widest at eyes. Disc densely punctate, nearly glabrous. Clypeus subquadrangular, as long as 1/3–2/5 head length, slightly depressed in basal part, surface glabrous and coriaceous, with scattered large punctures (same as those in vertex, but not so dense) in anterior part; anterior margin emarginate, and forward a little beyond anterior margin of supra-antennal ridges. Epistomal suture with lateral portions broadly incurved and running backward to level of anterior margin of eyes. Vertex densely punctate, slightly convex, posterior part welldemarcated from neck by occipital suture; two punctate paralateral sutures running anteriorly to middle level of head. Eyes with fine facets, longer than temples, and obviously protruding laterally. Temples punctate, weakly dilated. Occipital suture continuous in middle; nuchal ridge interrupted in middle, dorsal basal ridge present.

Mandible ( Fig. 16C) curved, with apices pointed; two denticles on inner edge. Antenna (type I) as long as head and pronotum together, with apical antennomere shorter than two preceding together.

Pronotum transverse, broadest at near anterior 1/3, wider than head. Disc 5-sulcate (as Fig. 1I), median sulcus and two paramedial sulci deep and punctate; two paralateral sulci oblique and shorter, each with punctate depression on lateral side. Lateral margins smooth, with posterolateral angles crenulate and prominent. Elytra punctate but not rugose, without lateral longitudinal ridge.

Abdomen coriaceous and pubescent, broadest at segment V. Sternite VII ( Fig. 16E) with two obsolete denticles near middle of posterior margin, weakly emarginate between. Posterior margin of sternite VIII ( Fig. 16F) protruding into subtriangular plate, at base of which with small pointed triangular tooth on each side, apical margin slightly emarginate in middle and with short and fine transverse carina behind. Tergite X ( Fig. 16H) longer than wide, posterior margin shallowly emarginate, with two lines of setae on haired posterior part.

Aedeagus ( Figs. 16K–N). Median lobe ovoid, with internal sac apex lingulate and everted from inside, with sclerite-like or membranous structures inside; apical orifice with ventral brim collar-formed and moderately separated from each side until apico-medial hook; apico-medial hook bent at near base, with apical tip sagitate, sharply pointed; dorsal membranous area covering most of dorsum. Paramere arm-like, with seta on apical 1/4, with apex a little twisted, with dorsal process alatiform.

Female. Head and mandible ( Figs. 16B, D) similar to male.

Abdominal sternite VII without denticles on posterior margin. Sternite VIII ( Fig. 16G) with posterior margin transparent, broadly rounded and obsoletely protruding in middle. Tergite X ( Fig. 16I) with posterior margin truncate.

Spermatheca ( Fig. 16J) ʋ- shaped, right-angled at middle, basal portion lightly bulbous, gradually narrowed apically.

Distribution. China (Hubei, Shaanxi, Sichuan, Xizang); Myanmar; Pakistan; India; Bangladesh.

Remarks. Cameron (1930) described O. discalis and pointed out it resemblance to O. punctipennis but according to the description the secondary male characters are different. We examined the holotype of O. punctipennis and the lectotype and paralectotypes of O. discalis and did not find any differences and therefore we consider O. discalis as a synonym.
