Types. Lectotype ♂ (MNHN), here designated, labeled: “[male aedeagus glued on card] // 686 / 69 [h, w, circle label] // 268 [h, w] // MUSEUM PARIS [p] / Coll. Générale [h, w] // Type [p, r] // Adorium / laticlavum / Farm [h, w]”. Paralectotype. 1♀ (MNHN): “686 / 69 [h, w, circle label] // MUSEUM PARIS [p] / Coll. Générale [h, w] // Type [p, r]”.
Redescription. Length 8.8–13.8 mm, width 7.7–11.1 mm. General color (Figs 19D–19F) yellow; antennomeres VIII–XI black; elytra with wide, longitudinal black bands extending from base to near apex, extending from near suture to epipleuron, transparent between lateral margin to epipleuron; metasternum darker except borders; one pair of black spots at sides of each abdominal ventrite; three apical tarsomeres darker. Antennae filiform in males (Fig. 45A), antennomeres I, III, and IV longest, VI–IX slender, length ratios of antennomeres I–XI 1.0: 0.5: 1.0: 1.0: 0.9: 0.8: 0.8: 0.8: 0.7: 0.7: 0.8, length to width ratios of antennomeres I–XI 3.3: 2.3: 4.2: 4.3: 3.8: 3.4: 3.0: 2.8: 2.6: 2.7: 3.2; similar in females (Fig. 45B) length ratios of antennomeres I–XI 1.0: 0.6: 1.0: 1.1: 0.9: 0.9: 0.7: 0.7: 0.7: 0.7: 0.9, length to width ratios of antennomeres I–XI 3.1: 2.2: 3.6: 3.8: 3.5: 3.1: 2.9: 2.7: 2.6: 2.8: 3.9. Pronotum transverse, 2.3 wider than long, disc convex, baso-laterally flattened, without reticulate microsculpture but with sparse, fine punctures; baso-lateral angles broadly rounded, apico-lateral angles narrowly rounded; lateral margin rounded; apical margin moderately concave. Elytra circular, widest at basal 1/3, as long as wide; disc without reticulate microsculpture but with dense, fine punctures, strongly convex, epipleurae located at 3/5 distance between suture and lateral margins, wide from base to basal 1/5, apically and gradually narrowed, abbreviated near apex; humeral calli reduced but visible, with curved depression posterior to calli. Penis (Figs 45C–45D) slender, 7.9x longer than wide; parallel-sided, apex of dorsal surface bifurcate at apical 1/5; tectum reduced; moderately curved in lateral view, apex hooked or narrowly rounded; ventral surface with shallow, broad and parallel notch from apex to apical 1/5, apices narrowly rounded; internal sac with one apical sclerite, V-shape, with V-shaped process at middle, hooked in lateral view. Apical margin of abdominal ventrite V in female truncate. Gonocoxae reduced. Ventrite VIII (Fig. 45E) transverse, apical margin angularly depressed, with dense, long and short setae along apical margin, with slender lateral processses, spiculum short and apically narrowed. Receptacle of spermatheca (Fig. 45F) apically widened, connected to pump, basally narrow, connected to proximal spermathecal duct; pump strongly curved, apex broadly rounded; proximal spermathecal duct slender.
Variation. Some specimens possess two pairs of black spots on the pronotum. In addition, sometimes the abdominal ventrites are entirely blackish brown. Some females possess acute apical processes on ventrite VIII. A few specimens possess entirely yellow elytra, and were probably teneral when collected.
Diagnosis. Adults of this species and those of O. boreri sp. nov., O. coccinelloides, and O. epipleuralis are easily recognized by the strongly convex elytra (epipleurae located at 3/5 distance between suture and lateral margins). But O. laticlava differs in possessing one pair of longitudinal black stripes on the yellow elytra (with several pairs of small black spots in O. coccinelloides; entirely yellow elytra in O. boreri sp. nov. and O. epipleuralis), and yellow venter (black venter in O. boreri sp. nov.; black metasternum, and one pair of black spots at sides of each abdominal ventrite in O. coccinelloides) and yellowish brown tarsi (black tarsi in O. boreri sp. nov.). In males, the aedeagi of O. laticlava differ from those of other species in the less elongate penis, less than 8.0x longer than wide (extremely elongate in O. boreri sp. nov., 9.3x longer than wide), shallow notch on the ventral surface (moderately deep notch in O. coccinelloides; extremely deep notch in O. boreri sp. nov.), and parallel lateral processes (directed inwards in O. boreri sp. nov. and O. epipleuralis). Moreover, the distributions are allopatric: O. boreri is restricted to Laos, O. cocconelloides is restricted to west China, India, and Myanmar, O. epipleuralis is endemic to Taiwan, and O. laticlava is restricted to other parts of China (Fig. 14).
Host plant. Vitaceae: Vitis spp. (Yu et al. 1996) (Figs 19G–19H).
Remarks. Aston (2009) confused O. bowringii with O. laticlava. Most of specimens collected by him are members of O. laticlava.
