Description. Male ( Figs 10A View FIGURE 10 , 11A – H View FIGURE 11 ). Body elongate, black, convex and dull-shiny.

Head ( Fig. 11A View FIGURE 11 ) distinctly transverse, dorsal surface finely covered with small punctures and short hair. Labrum narrower than clypeus, covered with bristles of medium length in apical portion. Antennal tubercles weak, antenna ( Fig. 11B View FIGURE 11 ) shorter than the combined length of head and pronotum, clubs loosely formed by apical four antenno-meres. Antennomere I slightly expanded; II shortest, longer than wide; III longest, about 2.5 times as long as II, IV-VII similar, shorter than III, apical four dark brown, expanded, XI with rounded apex.

Pronotum ( Fig. 11A View FIGURE 11 ) about as long as wide, widest at basal 1/3, dorsal surface finely covered with small punctures and short hair. Groove of pronotum much deep at base and lacking at anterior part, the back angle oblique indentation slightly short, deep, curved forward and upward, median line shallow.

Elytra about twice as long as wide, widest at apical 1/3, shoulders strong, Disc with regular rows of orderly foveolate punctures, scutellum transverse, near triangular. Hind wings fully developed.

Femora obvious expended at middle, all tibiae covered with brown setae at apex, protibiae ( Fig. 11C View FIGURE 11 ) straight and with a small expanded projection at middle, mesotibiae slightly curved, metatibiae straight.

Aedeagus ( Figs 11 View FIGURE 11 D–F), near symmetrical, abdominal ventrite VIII ( Fig. 11H View FIGURE 11 ) deeply split medially at posterior margin and with long dense hair at hind margin. Spiculum gastrale ( Fig. 11G View FIGURE 11 ) dissymmetrical, short, with large apical lobes.

Measurements. AnL 3.61–4.10 mm, BL 13.32–14.35 mm, HL 1.58–1.65 mm, HW 2.14–2.41 mm, PL 2.77–3.33 mm, PW 2.98–3.35 mm, EL 8.90–9.41 mm, EW 4.50–5.18 mm, AL 1.89 mm.

Female ( Figs 10B View FIGURE 10 , 11I – J View FIGURE 11 ). Similar to males, protibiae lack modification. Ventrite VIII ( Fig. 11I View FIGURE 11 ) split medially at posterior margin and covered with long dense hairs. Spiculum ( Fig. 11I View FIGURE 11 ) near straight, apex rounded and slightly dilated. Apex of ovipositor ( Fig. 11J View FIGURE 11 ) with one long hair and two much shorter hairs.

Measurements. AnL 3.10–4.09 mm, BL 12.28–14.36 mm, HL 1.34–1.63 mm, HW 1.97–2.42 mm, PL 2.60–3.30 mm, PW 2.72–3.33 mm, EL 8.34–9.43 mm, EW 4.30–5.20 mm.

Comparative Notes. The new species is similar to Hexarhopalus (Leprocaulus) bisinuatus Ren & Xu, 2011 ( Figs 18–19 View FIGURE 18 View FIGURE 19 ) in its general appearance, but can be separated from the latter by: 1) sparse foveolate punctures on the elytra; 2) less and short setae on the apex of protibia; 3) inner projection situated at the middle of protibia; 4) lateral groove of pronotum much shallow and not obvious at anterior part. Furthermore, the localities of the two species are distant (over 500 km).

Distribution. China: Yunnan.

Biology. The adult was collected by light trap.

Etymology. This species is named in honor of our friend Dr. Jian-Yue Qiu, the collector of the holotype.
