Description. Body ( Fig. 8–9 ) entirely black, except slightly reddish antenna, tarsi and tergites.

BL: 7.9–8.9 mm, FL: 6.8–7.6 mm.

HW: 1.47–1.67 mm, PW: 3.53–3.77 mm, EW: 3.53–3.82 mm, AL: 1.86–2.01 mm, PL: 2.01–2.16 mm, EL: 4.02–4.36 mm.

Head transverse; vertex with a pair of glossy patches, micropunctation separated by a cluster of numerous macropunctures; frons glossy and with micropunctation, laterally with punctures; lateral portion behind eye and area near medial margin of eye with very dense and coarse punctation. Antennae short with antennomeres 7–11 strongly dilated and forming a distinct club; antennomeres 4–6 as long as broad; antennomere 7 sub-spherical.

Pronotum approximately 1.7–1.8 times as broad as long and 2.2–2.4 times as broad as head, broadest at posterior third; lateral margins with moderate bead; disc with moderately dense micropunctation; punctation of disc coarse, dense laterally, sparser in the middle and absent on either side of the base.

Elytra approximately 2 times as long as pronotum; shoulders with a small tooth; each elytron with nine finely punctate striae; intervals flat and with micropunctation; posterior margins curved. Scutellum longitudinal. Legs short, outer margin of protibiae curved inwards in apical third and slightly concave between spines.

Abdomen with transverse microsculpture on tergites VII–VIII.

Male. Tergite VIII proximally broad, apically obtusely pointed; aedeagus ( Fig. 10–13 ) 1.7 mm long; parameres of aedeagus slender, apically acute and bent ventrad; median lobe slightly shorter than parameres in ventral view.

Female. Tergite VIII flat, wedge-shaped, apically obtusely pointed.

Distribution. China (Guangxi).

Diagnosis. Nodynus huapingensis sp. nov. can be distinguished from all known congeners by the combination of the following characters: elytra entirely black, the distinctive shape of pronotum and the distribution of pronotal punctation. The comparison summaries of the important characteristics between the new species and all the known species are presented in Table 2 .

Etymology. The species is named after its type locality, Huaping National Nature Reserve.
