Description of female. Habitus as in Fig. 13B ; body slightly convex, TBL 7.44–8.14 mm, FBL 5.32–5.46 mm; head and elytra black, antennomeres1–4 yellowish--brown, 5–11 yellow, elytra, pronotal disc, and most parts of legs reddish-brown. Head sub-pentagon, HL 1.03–1.17 mm, HW 1.36–1.41 mm, with microsculpture consisting of small isodiametric or nearly isodiametric meshes; posterolateral and posterior margins with microsculpture consisting of transverse waves; eyes prominent, EyL 0.37–0.42 mm; antennae elongate, AnL 2.72–3.02 mm, relative lengths of antennomeres 1–11: 2.0: 1.0: 1.6: 1.2: 1.2: 1.4: 1.4: 1.4: 1.2: 1.2: 1.6. Pronotum strongly transverse, PL 1.74–1.88 mm, PW 3.15–3.20 mm, PL/PW 0.55–0.58, with microsculpture as of head. Elytra transverse, EL 2.26–2.35 mm, EW 3.10–3.15 mm, EL/EW 0.72–0.74, with microsculpture consisting of transverse waves, and each elytron with five complete and one shorter rows of punctures. Abdominal surface with coarse punctures, and with microsculpture as elytra; tergite VIII ( Fig. 14K ) with five lobes, inner lobes longer than others, width of inner lobes sub-equal to middle ones, outer lobes short; sternite VIII ( Fig. 14L ) with six lobes, fimbriate lobes longer than others; styli as in Fig. 14M . Comments. The male ( Fig. 13A ) of Olophrinus nepalensis was originally described from Nepal, and this species is here proved to be widely spread in China (Guangxi, Yunnan, Xizang). The populations from China ( Figs 13–14 ) can be readily identified as conspecific with that from Nepal by each elytron with five complete rows of punctures, and the nearly identical forms of male terminal segments and aedeagus. Note the number of spiniform setae medially at the apical margin of male sternite VI may vary from four to eight. The female of this species is here described and illustrated for the first time.

Distribution. China: Guangxi, Yunnan, Xizang (new country record); Nepal ( Fig. 18 ).
