Description.
Male. Length 6.0 mm, width 3.4 mm.
Head, pronotum and scutellum blackish green, antennae, legs, and ventral surface of body brown, elytra and apex of each abdominal segment yellow; each elytron with seven black spots of different sizes, basal, middle and subapex each with one pair of spots, apex with one spot.
Vertex densely covered with punctures; frontal tubercles distinctly raised, each separated from each other by a deep furrow; antennae short, robust, extending to the middle of the elytra; antennomere 2 shortest, antennomere 3 slightly longer than 2, 1.2 × as long as second; antennomere 4 longest, twice as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than 4; antennomere 11 slightly longer than 10, pointed.
Pronotum approximately 1.9 × as wide as long, with rounded lateral margins; disc slightly convex, sparsely covered in middle with small punctures with large punctures on other parts. The interstices between punctures slightly narrower than diameter of individual punctures and lightly covered with small punctures in interstices.
Scutellum triangular, densely covered with punctures.
Bases of both elytra wider than the pronotum, gradually widen posteriorly and rounded at apex; dorsal surface slightly convex, irregularly covered with large and deep punctures, the interstices between punctures slightly narrower than diameter of individual punctures and lightly covered with small punctures in interstices.
Metasternum twice 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 3, three lobes.
Aedeagus slender, rounded laterally, basally widened, with triangular apex, slightly pointed. In lateral view moderately bent.
Female. Length 5.8 mm, width 3.3 mm.
Antennal antennomere 2 shortest, antennomere 3 slightly longer than 2, 1.4 × as long as second; apical sternite flatted.
Differential diagnosis.
This species can be distinguished from other species by the blackish green pronotum and blackish green spots of the elytra.
