Body length 7.26 mm to 8.42 mm (X‒ = 7.84 mm, s = 0.82, n = 2). Integument black. Dorsum densely covered with fine brownish black appressed scales with purple and gold metallic reflectance, reflectance particularly pronounced laterally and posteriorly. Femora and tibiae with appressed scales dense, unicolorous, concolorous with elytral scales. Tarsi with integument strong red. Rostrum.

Epifrons with appressed scales tessellate; setae piliform, decumbent, pale; median and lateral carinae not evident. Dorsal carinae arched over antennal insertions. Lateral area ventral of antennal insertions with fine setae and appressed scales. Antennae. Fig. 36. Scapes in repose reaching hind margin of eyes; covered with appressed scales and setae.

Anterior margin entire, posterior margin straight. Disc in dorsal view evenly curved; appressed scales imbricate; setae piliform, decumbent, concolorous. Postocular lobes moderately developed. Elytra. Length 4.90 mm to 5.70 mm (X‒ = 5.30 mm, s = 0.57, n = 2), width 2.85 mm to 3.53 mm (X‒ = 3.19 mm, s = 0.48, n = 2), length/width ratio 1.61 to 1.72 (X‒ = 1.67, s = 0.07, n = 2). Anterior margin almost straight, humeral angles rounded. Appressed scales imbricate. Setae piliform, erect, pale. Striae moderately impressed; interstriae flat; interstriae 1 at elytral declivity flat in males, with small tubercle in females. Apex in lateral view square in males, produced posteriad in females. Thoracic ventrites. Mesoventral process acutely rounded in males, broadly rounded in females. Metaventrite densely covered with appressed scales. Abdomen. Ventrites densely covered with appressed scales. Apex rounded. Males with ventrite 1 depressed medially; ventrite 5 flat. Females with ventrite 1 flat; ventrite 4 posterior margin curved anteriad in middle, with narrow laminae laterally (Figs 110, 111); ventrite 5 swollen medially, posterior margin broadly emarginate. Male genitalia. Figs 76-79. Hemisternites with spiculum relictum slender. Penis with apex narrowly rounded, upturned; ostial region normally developed. Endophallus with gonoporial sclerite small, posterior lobes reduced. Temones 0.63 times as long as pedon. Female genitalia. Figs 80-84. Distal gonocoxites stout, 1.4 times longer than high. Bursa copulatrix stout; constricted anterior of proximal gonocoxite; sclerite large, pear-shaped. Sternite 8 broad, rounded at apex, membranous laterally. DNA sequences. No DNA sequences obtained.
