Redescription. Size: Total length (without labrum) 7.5–9.6mm (mean = 8.6mm, n = 30). Head: Black coppery above; greenish ventrally, surface glabrous, with each two setigerous punctures next to the eyes in front and at the centre; with very strong transverse striae on frons and very strong longitudinal striae on orbital plates, furrows on vertex wrinkled; genae finely striated transversally, brassy near the eyes, the remaining greenish. Ratio of width of head to width of elytra = 0.9 in medium. Labrum (male Fig. 8 , female Fig. 9 ) wider than long, ratio of length to width = 0.7 in medium; with a medial carina, a blunt short tooth in the middle of front edge in males, a longer pointed tooth in female, and with six marginal setae; color yellow, anterior margin and anterior part of carina black, setigerous punctures black; mandibles yellowish, with four black teeth. Labial and maxillary palpi testaceous, apical segment black, penultimate segment of labial palpi dilated, with long erected white setae. Antennae slender, long, reaching behind the basal third of the elytra in males, behind the shoulders in females; antennomeres one to four dark, with metallic luster; scape with one long apical seta, the other three antennomeres almost glabrous; antennomeres five to eleven dark blackish brown, dull, finely and evenly pubescent. Thorax: Pronotum as wide as long (ratio of length to width = 1.0 in medium), sides somewhat rounded between the transversal constrictions; glabrous, covered with white setae laterally; with shallow wrinkled furrows; color blackish coppery. Sternae and episternae coppery; proepisternum with several white setae; mesepisternum glabrous, smooth, without distal furrow in the female; metepisternum setose. Elytra: ( Fig. 10-12 ) parallel-sided, slightly extended laterally; blackish brown with greenish and coppery reflec- tions laterally; deeply punctuate with some metallic coppery or green foveae along suture and at inner humeral angle, punctures shallower towards apical suture; surface slightly unevenly contoured on disc with longitudinal ridge on basal two thirds near the metallic foveae; elytral apex rounded, microserrulate, with retracted tiny sutural tooth; elytral testaceous maculation consists of three roundish dots, a variable (small to nearly extinct) marginal one, a tiny central one and a larger apical one, which shows an apical extension. Epipleurae dark brownish. Ventral aspect: Venter setose, coppery; coxae with white setae; trochanters testaceous; coxae and femora shiny green, knee brownish yellow; tibiae brownish yellow, darkened apically; tarsi brownish black; legs covered with some with setae, mesotibiae more densely setose. Aedeagus: ( Fig. 13 ) moderately bulky and wide on middle third, gradually tapering towards apex, apex slender and evenly extracted, forming a fine hook (total length 2.6mm).
