Description. Body length 4.2–4.9 mm; forebody length 2.4–2.7 mm.

Body ( Fig. 8 View Figure ) reddish brown; antennae and legs yellowish brown.

Head ( Fig. 19 View Figure ) approximately as long as wide; punctation very dense, moderately coarse, non-umbilicate and not confluent, interstices with very fine microsculpture; postocular portion approximately twice as long as eye length.

Pronotum ( Fig. 19 View Figure ) 1.06–1.20 times as long as wide, approximately as long and 0.87–0.94 times as broad as head; punctation similar to that of head; midline posteriorly with short and very narrow impunctate elevation; interstices lacking microsculpture.

Elytra ( Fig. 19 View Figure ) 0.63–0.69 times as long as wide, 0.54–0.61 times as long and 0.95–0.99 times as broad as pronotum; punctation as dense as, and slightly less coarse than that of pronotum; interstices lacking microsculpture.

Abdomen with punctation dense and moderately coarse on tergites III–IV, dense and less coarse on tergite V– VI, moderately dense and fine on tergites VII–VIII; interstices with fine microsculpture.

Male. Sternite VII ( Fig. 20 View Figure ) with posterior margin small excision in the middle. Sternite VIII ( Fig. 21 View Figure ) with Vshaped posterior excision. Aedeagus ( Figs 22, 23 View Figure ) with ventral process gradually narrowed apically in ventral view, with pair of wing-like basal laminae ventrally; dorso-lateral apophyses short, distinctly slender in apical half in ventral view, not reaching apex of ventral process.

Distribution and habitat. The species is known from Nanling in northern Guangdong and Mangshan in southern Hunan. The specimens were collected by sifting leaf litter at altitudes of 1260 –1820 m.

Comparative notes. The new species is very similar to N. jiaweii Hu, Liu & Li  in general appearance and aedeagal characters, but can be separated by the narrower posterior excision of male sternite VIII ( Fig. 21 View Figure ), and much shorter dorso-lateral apophyses of the aedeagus ( Figs 22 View Figure ).

Etymology. The specific epithet is dedicated to Lei Gao, who collected some of the type specimens.
