13FBBC52F14952379F422F6DA57AC31E.taxon	description	Description. Male. Body (Fig. 1 A, B) flat, surfaces shiny, sides nearly parallel. Eyes black; ventral surface, antennae and legs generally yellowish brown; head, apices of femora and bases of tibiae metallic green with a brownish sheen; tarsi reddish brown; pronotum yellowish brown with a greenish sheen; lateral margin of pronotum and elytra blackish brown; each elytron with one brownish markings from striae 1 to striae 8, reaching apical one-quarter but not reaching the basal margin; remaining areas yellowish green with metallic reflection. Head triangular, distinctly constricted behind eyes; anterior margin densely covered by tiny punctures and remaining dorsal surface randomly punctate; ventral surface (Fig. 1 D) densely punctured on gular area, with even pubescence coverage, and genal area with dense elliptical punctures. Mentum (Fig. 1 D) transverse, nearly rectangular, with anterior margin concave. Antenna with 11 antennomeres, including a 3 - segmented club. Thorax. Pronotum nearly trapezoidal, widest across posterior one-third; pronotal disc punctate, weakly convex, punctures denser and larger laterally; anterior angles obtuse, moderately protruding anteriad, posterior angles acute; anterior margin convex, slightly concave at middle; lateral margins weakly serrated, posterior margin distinctly bisinuate. Prothoracic hypomera with sparse punctures. Prosternum, meso- and metaventrites smooth, without punctures at middle. Scutellar shield glabrous, nearly semicircular, lateral margins truncate. Elytra oblong, widest at basal two-fifths, parallel-sided at basal three-quarters, then gradually narrowing, with apices rounded; each elytron with 10 punctured striae, intervals flat, evenly covered with micro-punctures; lateral margins weakly bordered, apex of each elytron with 1 – 2 obscure notches (Fig. 1 F); epipleura wide, without punctures. Legs. Femora surfaces smooth, weakly dilated. Protibiae (Fig. 1 E) curved, inner side notched and clothed with sparse pubescence on apical one-third. Tarsi simple, tarsomeres I – IV clothed with dense pubescence on ventral surface, tarsomere V longer than the combined length of tarsomeres I – IV. Abdomen slightly convergent from abdominal ventrite I towards apex; abdominal ventrite V (Fig. 2 D) with sparse short setae at middle; apical margin slightly sinuate, with dense short setae that are densest at the apex. Abdominal tergite VIII (Fig. 2 C) subquadrate, antero-lateral angles rounded; apical margin truncate, with long setae. Male genitalia. Penis (Fig. 2 B) elongate, with rounded lateral margins, narrowing towards the rounded apex, apical orifice elongate, elliptical (from basal fourth to apical fourth), with long subparallel lobes. Tegmen (Fig. 2 A) slender, apical margin with sparse apical setae and a relatively deep notch at middle, basal margin truncate. Internal sac (Fig. 2 E, F) with four sclerites basally, one dorsal sclerite long and slender, strongly curved, hooked at base, one ventral sclerite oblong, two paramedian sclerites short, basally expanded.

Similar to male but with body larger; protibiae straight, without notches; and elytral apices (Fig. 1 G) with 2 – 3 distinct teeth. Ovipositor short; paraproct and proximal gonocoxite moderately sclerotized; and distal gonocoxite and gonostylus elongated, slender, and well sclerotized (Fig. 2 G, H). Measurements (in mm).
