Redescription. Color generally purplish blue, some individuals with elytra golden green or bronzy golden green; abdomen yellowish brown (Figs. 6–8). Head smooth, with traces of microreticulation, vertex impunctate. Pronotum transverse, about 1.9–2.1X wider than long, disc with microreticulation and scattered small and minute punctures; lateral margins rounded; anterior margin moderately concave, posterior margin widely rounded; anterior angles obtuse; posterior angles weakly angulate. Elytra 1.4X longer than wide, widened posteriad, widest at apical 1/3; disc with distinct punctures irregularly arranged into longitudinal rows; interstices between longitudinal rows with scattered minute punctures.
Male. Length 9.0– 9.7 mm, width 5.0– 5.4 mm. Antenna (Fig. 13) 0.8X as long as body, antennomeres IV-XI flattened and laterally widened, ratio of length of antennomeres IV to XI about 1.0: 0.9: 0.9: 0.9: 0.9: 0.9: 0.9: 1.2; ratio of length to width of antennomeres IV to XI about 2.2: 1.6: 1.6: 1.6: 1.5: 1.6: 1.6: 2.6. Posterior margin of last ventrite with 1 pair of shallow depressions near apex. Penis (Fig. 21) slender and tubular, apex widely rounded; in lateral view almost straight, slightly curved at apex; ventral surface flat (Fig. 22). Endophallic sclerites (Fig. 25) composed of 1 median sclerite and 1 pair of lateral sclerites. Median sclerite longitudinal, in lateral view with cluster of short setae at apical 1/3, baso-dorsal apophysis much longer than baso-ventral apophysis; 1 pair of lateral sclerites as long as median one, slender and strongly curved near apices, apex hook-like, with small tooth near apex.
Female. Length 10.4–11.0 mm, width 5.6–5.9 mm. Antenna (Fig. 14) comparatively narrower and shorter than in male, 0.6X as long as body, ratio of length of antennomeres IV to XI about 1.0: 0.9: 0.9: 0.9: 0.8: 0.8: 0.8: 1.2; ratio of length to width of antennomeres IV to XI about 2.8: 2.5: 2.2: 2.0: 1.8: 1.8: 1.8: 2.9. Posterior margin of last ventrite widely rounded. Gonocoxae (Fig. 29) wide and straight, connected from middle to base; apex obliquely truncate, with more than 10 long setae; base widened and weakly sclerotized. Sternite VIII (Fig. 32) with apex weakly sclerotized, apical margin visible and straight; disc with long setae surrounding outer margin; spiculum long. Spermathecal receptaculum (Fig. 35) strongly swollen, pump narrow and strongly curved, spermathecal duct long and slender, shallowly projecting into receptaculum.
Variation. Males from Taiwan have lateral sclerites with shorter hook-like apices and a median sclerite with longer baso-ventral apophysis (Fig. 26) than Chinese ones. Females from Taiwan have wider antennae (ratio of length to width of antennomeres IV to XI from northern Taiwan about 2.1: 1.6: 1.4: 1.3: 1.2: 1.2: 1.2: 2.1 (Fig. 16); from southern Taiwan about 3.0: 2.2: 1.7: 1.5: 1.4: 1.4: 1.4: 2.4 (Fig. 15))
Distribution. China, Indochina, Taiwan.
