Males ( Figs 5 View FIGURE 5 A–5C). Length 6.2–6.7 mm; width 3.7–3.9 mm. Antenna ( Fig. 6 View FIGURE 6 A) long, filiform, about 1.1x longer than body, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 1.0: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.9, length to width ratios of antennomeres I–XI 3.3: 1.8: 3.1: 4.6: 4.4: 4.4: 4.5: 5.5: 6.1: 5.4: 7.0. Elytra apically weakly broadened; about 1.2-1.3x longer than wide; surface with sparse, coarse punctures and several indistinct longitudinal ridges. Apical margin of last abdominal ventrite with two well developed incisions. Penis ( Figs 6 View FIGURE 6 C– 6D) elongate, about 5.1x longer than wide, gradually narrowed towards middle, apex lanceolate, strongly curved in lateral view; endophallic sclerite long, about 0.8x as long as penis, slender and longitudinal, apical margin rounded, with dense short hairs along lateral margin at middle, bifurcate at basal 1/6.

Females ( Figs 5 View FIGURE 5 D–5F). Length 6.9–7.3 mm, width 4.5–4.7 mm. Antenna ( Fig. 6 View FIGURE 6 B) long, filiform, as long as body, length ratios of antennomeres I–XI 1.0: 0.3: 0.7: 0.9: 0.9: 0.8: 0.8: 0.8: 0.8: 0.8: 0.8, length to width ratios of antennomeres I–XI 4.0: 1.5: 3.1: 4.6: 4.9: 5.5: 5.3: 5.6: 6.5: 5.8: 7.1. Elytra strongly broadened apically; about 1.0–1.1x longer than wide; surface with sparse, fine punctures and several indistinct longitudinal ridges. Apical margin of last abdominal ventrite subtruncate. Gonocoxae ( Fig. 6 View FIGURE 6 E) longitudinal and narrow, 3.2x longer than wide, conjoined from base to middle, slightly narrowed in apical 1/3, apices rounded, each gonocoxa with eight elongate setae. Ventrite VIII ( Fig. 6 View FIGURE 6 F) with only apical area and spiculum sclerotized; with dense elongate setae inside apical sclerotized area, apical margin rounded; spiculum elongate and broad. Receptacle of spermatheca ( Fig. 6 View FIGURE 6 G) slender, as wide as pump, hardly separated from pump; pump broad and strongly curved, apex broadly rounded, apex with transverse, broad sclerite ( Fig. 6 View FIGURE 6 H), size variable; proximal spermathecal duct hardly separated from receptacle, apically narrowed.
