Description. Male. Length 7.7-8.4 mm, width 5.2-5.8 mm. Head, pronotum and elytra green, antennae, scutellum, legs, and ventral surface of thorax dark blue, abdomen yellowish brown. Some individuals with blue or red head, pronotum, and elytra. Vertex finely and sparsely covered with punctures; frontal tubercle distinctly raised, separated from each other by a deep furrow; antennae short, robust, extended to the middle of elytra; antennomeres 1-3 thin, shiny; antennomeres 4-11 wide and flat, with short hairs, antennomere 4 approximately twice as long as wide; antennomeres 5-11, each approximately 1.5 x as long as wide; antennomere 2 shortest, antennomere 3 slightly longer than 2, 1.2 x as long as second; antennomere 4 longest, 1.2 x as long as antennomeres 2 and 3 combined; antennomeres 5-10 unequal in length, shorter than 4; antennomere 11 slightly longer than 10, pointed. Pronotum approximately 2 x as wide as long, with rounded lateral margins; disc slightly convex, sparsely covered with punctures. Scutellum triangular, with rounded apex, smooth, impunctate. Bases of both elytra wider than pronotum, gradually widen posteriorly and rounded at apex; dorsal surface slightly convex, irregularly covered with punctures, densely covered with large punctures on humeral angle and sparsely covered in small punctures on other parts. The interstices between punctures wider than diameter of individual punctures on apex of the elytra, 2 x as wide as the diameter of individual punctures. Metasternum 2.5 x as long as mesosternum; prothoracic legs shortest, mesothoracic legs slightly longer, metathoracic legs longest. Ventral surface of abdomen with five segments, segment 1 longest, segments 2-4 gradually shortened, apical segment slightly longer than segment 4, with three lobes. Aedeagus slender, parallel-sided, basally widened, apically rounded, slightly pointed. In lateral view strongly bent. Female. Length 7.8-8.4 mm, width 5.3-5.8 mm. Antennae antennomeres 1-3 thin, antennomeres 7-11 wide and flat, with short hairs, antennomere 7, twice as long as wide; antennomeres 8-11 each approximately 1.6 x as long as wide; antennomere 2 shortest, antennomere 3 longer than 2 slightly, 1.5 x as long as second; antennomere 4 longest, slightly longer than antennomeres 2 and 3 combined; apical sternite flatted. Differential diagnosis. This species can be distinguished from other species by metallic green, red, or blue coloration of the body. Distribution. China: Henan, Zhejiang, Jiangxi, Hunan, Fujian, Taiwan, Guangdong, Guangxi, Sichuan, Guizhou, Xizang; Indo-China. Host plant. Rubiaceae . Figure 5.
