Redescription. Length 8.5–11.1 mm, width 5.0– 6.7 mm. General color ( Figs 8A–8C View FIGURE8 ) yellow; elytra metallic blue but with wide yellow lateral margin and suture, blue area apically tapering and abbreviated near apex. Antennae filiform in males ( Fig. 9A View FIGURE 9 ), antennomeres IV longest, VI–IX slender, length ratios of antennomeres I–XI 1.0: 0.6: 0.9: 1.3: 1.1: 0.9: 0.9: 0.8: 0.7: 0.6: 0.7, length to width ratios of antennomeres I–XI 2.3: 1.8: 2.5: 3.7: 3.1: 2.7: 2.9: 2.9: 2.6: 2.6: 3.3; more slender in female ( Fig. 9B View FIGURE 9 ), length ratios of antennomeres I–XI 1.0: 0.5: 0.9: 1.4: 1.1: 1.0: 0.9: 0.8: 0.7: 0.6: 0.7, length to width ratios of antennomeres I–XI 2.7: 1.8: 2.8: 4.4: 3.6: 3.4: 3.2: 3.4: 3.1: 2.8: 3.7. Pronotum transverse, 2.1x wider than long, disc slightly convex, with lateral fovea, lateral margins flattened, with reticulate microsculpture and sparse, coarse punctures; baso-lateral angles angular, apico-lateral angles broadly rounded; lateral margin rounded; apical margin slightly concave. Elytra elongate oval, widest at middle, 1.4x longer than wide; disc without reticulate microsculpture but with dense, coarse punctures, slightly convex, epipleurae near lateral margins, located 9/10 distance between suture and lateral margins, wide from base to basal 1/5, apically narrowed and abbreviated at middle; humeral calli prominent. Penis ( Figs 9C–9E View FIGURE 9 ) slender, 8.8x longer than wide; parallel-sided, apex of dorsal surface deeply bifurcate at apical 1/4, apical processes narrowly rounded; tectum reduced; slightly curved in lateral view, apex narrowly rounded; apex of ventral surface with extremely deep and subapically broadened notch from apex to basal 1/5. Apical margin of abdominal ventrite V in female broadly rounded. Gonocoxae reduced. Ventrite VIII ( Fig. 9F View FIGURE 9 ) transverse, apical margin broadly rounded and weakly depressed at middle, with row of long setae along apical margin; spiculum extremely short. Receptacle of spermatheca ( Fig. 9G View FIGURE 9 ) as wide as pump, connected to pump; pump strongly curved; proximal spermathecal duct membranous, slender and short, sclerotized area at apex covered with transverse lows of short teeth.

Variation. Some individuals possess entirely yellow head and antennae, and only basal half of metallic blue areas on the elytra ( Fig. 8D View FIGURE8 ). Some specimens possess black head and dark spots on the pronotum but the metallic blue stripes on elytra not developed well ( Fig. 8E View FIGURE8 ). Few specimens possess the metallic blue area on elytra extending into suture, presence of one pair of large dark spots on the pronotum, and the entire dark brown antennae, which were described as Oides maculicollis ( Fig. 8F View FIGURE8 ).

Diagnosis. Adults of this species are characterized by the wide metallic blue stripes on the elytra that are abbreviated apically. However, a few specimens possess metallic blue stripes that extend to the apex, similar to those of Oides cyanella Jacoby but differing in possessing wide, yellow lateral margins on elytra. The aedeagi of adult males of O. apicalis lack a tectum and endophallic sclerites, and possess rounded apices of the penis, but those of O. cyanella possesses an elongate tectum and one pair of curved endophallic sclerites, and hooked apices of the penis.
