Redescription. Length 10.5–13.7 mm, width 7.6–9.9 mm. General color (Figs 22A–22C) yellow; antennae yellow, but antennomeres IX–XI darker; metasternum with one black spot at sides; elytra with five pairs of black spots, arranged into three transverse row, two pairs near base, two pairs at middle, and one near apex. Antennae filiform in males (Fig. 23A), antennomeres III longest, III–VII weakly serrate, VIII–X stout, length ratios of antennomeres I–XI 1.0: 0.6: 0.8: 0.8: 0.7: 0.7: 0.7: 0.6: 0.6: 0.6: 0.7, length to width ratios of antennomeres I–XI 2.5: 1.8: 2.7: 2.7: 2.0: 1.9: 1.9: 1.8: 1.8: 1.7: 2.0; similar in females (Fig. 23B), length ratios of antennomeres I–XI 1.0: 0.5: 0.8: 0.8: 0.7: 0.7: 0.7: 0.6: 0.6: 0.5: 0.7, length to width ratios of antennomeres I–XI 2.7: 2.0: 3.0: 2.8: 2.2: 2.2: 2.2: 1.6: 1.6: 1.5: 2.2. Pronotum transverse, 2.2 wider than long, disc convex, with reticulate microsculpture and dense, fine punctures; baso- and apico-lateral angles broadly rounded; lateral margin rounded; apical margin moderately concave. Elytra elongate oval, widest at middle, 1.2x longer than wide, disc with reticulate microsculpture and dense, coarse punctures; moderately convex, humeral calli reduced but visible, with curved depression behind; epipleurae located at 5/7 between suture and lateral margins. Penis (Figs 23C–23G) relatively wider, 6.3 longer than wide; parallel-sided; apex medially and slight depressed; tectum elonage, ventrally curved at basal 1/3, deeply bifurcate near base, apices projected from penis; slightly curved in lateral view; apex hooked in lateral view; ventral surface apically membranous. Apical margin of abdominal ventrite V in female truncate or slightly concave. Gonocoxae separated and transverse, apically tapering (Fig. 23K). Ventrite VIII (Fig. 23H) transverse, apical margin broadly rounded and with a pair of processes at middle, with short setae along apical margin, extremely dense at processes, spiculum short. Receptacle of spermatheca (Fig. 22J) 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 minute setae.
Variation. Specimens collected from Laos and Vietnam possess one pair of black spots laterally on each abdominal ventrite, and some specimens possess larger spots on the elytra (Fig. 22D), the latter occasionally connected (Fig. 22E). Females in Taiwan possess reduced apical processes of ventrite VIII (Fig. 23I) and longitudinal gonocoxae (Fig. 23L).
Diagnosis. Adults of Oides decempunctata are similar to those of O. coccinelloides, O. duodecimpunctata, and O. maculosa in possessing small, black spots on the elytra arranged into three transverse rows. They differ from others in possessing an entirely yellowish brown pronotum (one pair of lateral black spots at the pronotum in O. coccinelloides, O. duodecimpunctata, and O. maculosa) and scutellum (black scutellum in O. duodecimpunctata and O. maculosa), one pair of black spots near the apices of the elytra (two pairs in O. coccinelloides and O. duodecimpunctata; three pairs in O. maculosa), and the moderately convex elytra (epipleurae located at 5/7 distance between suture and lateral margins; strongly convex elytra in O. coccinelloides, epipleurae located at 3/5 between suture and lateral margins; less convex elytra in O. duodecimpunctata and O. maculosa, epipleurae located at 9/10 between suture and lateral margins). Aedeagi of male O. decempunctata differ from others with possessing a recurved tectum (lacking tectum in O. coccinelloides; small and apically tapering tectum in O. duodecimpunctata; bifurcate and rounded tectum in O. maculosa), membranous apex (deep and broad notch at ventral surface in O. duodecimpunctata and O. maculosa; deep and narrow notch at ventral surface in O. coccinelloides), and lacking endophallic sclerites (one large, hook and erect sclerite in O. maculosa; one elongate and parallel-sided sclerite in O. duodecimpunctata; one small, hooked, and erect endophallic sclerite in O. coccinelloides).
Host plants. Vitaceae: Vitis vinifera (grape) (Gressitt & Kimoto 1963; Lee & Cho 2006); V. coignetiae Pulliat ex Planch (Lee & Cho 2006); V. flexuosa Thunb. (Lee & Cho 2006); V. amurensis Rupr. (Lee & Cho 2006); Vitis sp. (Medvedev & Dang 1982); Ampelopsis brevipedunculata (Maxim.) (present study; Lee & Cho 2006); Parthenocissus tricuspidata (Siebold & Zucc.) Planch (Lee & Cho 2006); Menispermaceae: Cissampelos sp. (Medvedev & Dang 1982).
Biology. Taiwanese populations of Oides decempunctata are presumably univoltine. Some females were found during late January, 2007 in Tainan and transferred to the laboratory for rearing. Eggs were deposited in a single egg mass (Fig. 24A) during late February and required approximately one month to hatch. The larvae (Fig. 24B) fed on leaves and the larval duration was 24–26 days. Mature larvae (Fig. 24C) burrow into soil and pupated within underground chambers. The pupal stage duration was 15–20 days. Newly emerged adults appeared during spring and were active (Fig. 24D) during summer and autumn. A similar life cycle was documented in China (Yu et al. 1996).
