Types. Lectotype ♂ (BMNH), here designated, labeled: “[aedeagus glued on card] // SYN- TYPE [p, w, circle label with blue border] // Thibet [h, w] // Jacoby Coll. / 1909-28 a, [p, w] // Oides / thibettana / Jac. [h, b]”. Paralectotype. 1♀ (BMNH), same data as lectotype.

Redescription. Length 8.8–9.9 mm, width 7.3–8.0 mm. General color yellow; antennae yellow, but antennomeres VI–XI darker; meso- and metathoracic and abdominal ventrites blackish brown; legs yellow. Antennae filiform in males ( Fig. 66A View FIGURE66 ), antennomeres III longest, III–VII slightly serrate, VIII–XI elongate, length ratios of antennomeres I–XI 1.0: 0.5: 1.0: 0.8: 0.8: 0.8: 0.8: 0.7: 0.7: 0.6: 0.8, length to width ratios of antennomeres I–IX 2.8: 1.8: 3.5: 2.7: 2.8: 2.8: 2.5: 2.4: 2.2: 2.1: 2.8; a little broader in female ( Fig. 66B View FIGURE66 ), length ratios of antennomeres I–XI 1.0: 0.5: 1.0: 0.9: 0.8: 0.8: 0.7: 0.7: 0.7: 0.6: 0.8, length to width ratios of antennomeres I–IX 2.4: 1.7: 3.6: 3.0: 2.7: 2.6: 2.5: 2.2: 2.1: 2.0: 2.6. Pronotum transverse, 2.1x wider than long, disc without reticulate microsculpture but with dense, fine punctures, baso-lateral angles rounded, apicolateral angles rectangular, apical margin moderately concave. Elytra elongate oval, widest at middle, 1.1x longer than wide, disc without reticulate microsculpture but with dense, fine punctures; moderately convex, epipleurae located 7/10 distance between suture and lateral margins; humeral calli visible, surrounded by curved depression.

Penis ( Figs 66C–66G View FIGURE66 ) broad, 6.0x longer than wide; widest at apical 1/6, narrowest at basal 1/3, narrowed from apical 1/6 to basal 1/3; apically bifurcate, apices approximate; tectum reduced; slightly curved in lateral view, apex hooked; ventral surface with shallow and narrow notch at apex, inside apex membranous; endophallic sclerite complex comprising one pair of lateral sclerites, apex acute and base swollen, base connected with dorsal surface of penis. Apical margin of abdominal ventrite V in female slightly concave, depressed at middle. Gonocoxae reduced. Ventrite VIII ( Fig. 66H View FIGURE66 ) transverse, medial area projecting anteriorly and erect, apical margin truncate or medially depressed, with long setae along apical margin, much denser at medially; disc with circular depression near middle of apical margin, spiculum long. Receptacle of spermatheca ( Fig. 66I View FIGURE66 ) as wide as pump, connected to pump, basally narrowed; pump strongly curved; proximal spermathecal duct short, with narrowed apical sclerotized area at apex and covered densely with minute spines.

Diagnosis. This species is a member of the O. tarsata species group. For differences between species see diagnosis of O. geiseri sp. nov.
