Redescription. Length 11.9–14.9 mm, width 8.4–10.0 mm. General color ( Figs 15A–15D ) yellow; antennae yellow, antennomeres VIII–XI black; elytra metallic blue or green, with yellow wide band along lateral margin; tarsi blackish. Antennae filiform in males ( Fig. 16A ), antennomeres IV longest, III–VII weakly serrate, VIII–XI elongate, length ratios of antennomeres I–XI 1.0: 0.5: 1.0: 1.1: 1.0: 1.0: 1.0: 0.9: 0.8: 0.7: 0.8, length to width ratios of antennomeres I–XI 2.7: 1.6: 3.0: 3.2: 3.0: 2.9: 2.9: 2.7: 2.4: 2.0: 3.0; relatively broader in female ( Fig. 16B ), length ratios of antennomeres I–XI 1.0: 0.4: 1.0: 1.0: 0.9: 0.8: 0.9: 0.7: 0.7: 0.6: 0.7, length to width ratios of antennomeres I–XI 3.0: 1.7: 3.8: 3.8: 3.1: 2.6: 2.7: 2.3: 2.2: 2.0: 2.7. Pronotum transverse, 2.2 wider than long, disc convex but sides flattened, without microsculpture but with dense, fine punctures; basolateral angles broadly rounded, apico-lateral angles narrowly rounded; lateral margin rounded; apical margin weakly concave. Elytra elongate oval, widest at middle, 1.2x longer than wide, disc without reticulate microsculpture but with dense, fine punctures; moderately convex, epipleurae near lateral margins, located 9/10 distance between suture and lateral margins. Penis ( Figs 16C–16E ) slender, 7.2 x longer than wide; parallel-sided; bifurcate at apical 1/7, lateral process directed mesally and apically, apices of lateral processes rounded, apices approximate; tectum small and apically tapering; slightly curved in lateral view, apices hooked, concave at apical 1/5; ventral surface with shallow, broad but apically narrowed notch at apex; endophallic sac with one pair of elongate sclerites, weakly sclerotized. Apical margin of abdominal ventrite V in female truncate and with a pair of small rounded processes at middle. Gonocoxae ( Fig. 16F ) separated and hooked, with one row of long setae along apical margins. Ventrite VIII ( Fig. 16G ) transverse, apical margin broadly rounded and medially depressed or forming rounded processes, with extremely dense, long setae at apex, spiculum long and broad. Receptacle of spermatheca ( Fig. 16H ) as wide as pump, connected to pump, basally narrowed; pump strongly curved; proximal spermathecal duct membranous, slender and short, sclerotized area at apex broader than base of receptacle, covered with transverse grooves.

Variation. Some specimens possess yellow bands on the elytra extending into suture; some possess black antennomeres VI–XI and yellowish-brown tarsi. Specimens from Southeast Asia possess wider yellow lateral margins of the elytra ( Fig. 15E ).

Diagnosis. Members of O. bowringii (Baly) and O. metallica Jacoby are easily recognized by their broadly oval, metallic blue elytra, but the former differs from the latter by the presence of yellow lateral margins on the elytra (entirely metallic blue elytra in O. metallica ). Adult males of O. browringii possess a hooked aedeagal apex, a ventral concavity near the apex, and one pair of elongate endophallic sclerites. Those of O. metallica possess a rounded apex, straight venter, and lack endophallic sclerites.

Host plants. Schisandraceae : Kadsura japonica (L.) Dunal. ( Chûjô & Kimoto 1961); Schisandra repanda (Siebold & Zucc.) Radlk (= Schisandra nigra (Maxim.) Nakai , recorded by Chûjô & Kimoto 1961); S. chinensis (Turcz.) Baill ( Yu et al. 1996) .

Distribution. China, Japan, Laos, Myanmar, Vietnam ( Fig. 17 ). The record from Korea ( Fairmaire 1889) is doubtful since no other specimens have been collected from that country ( Lee & An 2001). The population in Japan is supposed to be introduced already before 1913 ( Morimoto & Kiritani, 1995); the species is established and occurs in the wild ( Mito & Uesugi, 2004). It was firstly reported from Hyogo Prefecture ( Seki 1933), then Kyoto ( Tomokuni 1966), Okayama ( Katayama & Fujitani 2005), Osaka ( Takahashi 2012). Oides bowringii is widely distributed in Hyogo pref., and especially common in Rokko-zan. This species is also recorded from Osaka, Kyoto and Okayama prefectures, but is uncommon in these prefectures ( Takahashi 2002).
