Type material. Holotype: China: male:‘ China: Guangxi, Jinxiu County, Shengtang Shan , 23°59′32″N, 110°06′26″E, mixed leaf litter, sifted, 1150 m, 23.VII.2014, Zhong Peng leg.’ ( SNUC) GoogleMaps . Paratypes: 2 males, same data as holotype GoogleMaps ; 1 male, 2 females, same data, except ‘ 23°57′37″N, 110°06′46″E, beech forest, mixed leaf litter, humus, sifted, 1300 m, 20.VII.2014, Peng, Song, Yu & Yan leg. GoogleMaps ; 1male, 5 females, same data, except ‘ 1200–1400 m, 25.VII.2012, Hu & Yin leg. GoogleMaps ’.

Description. Body length 4.2–4.9 mm; forebody length 2.5–2.7 mm.

Body ( Fig. 1 View FIGURES 1–3 ) reddish brown; antennae and legs yellowish brown.

Head ( Fig. 4 View FIGURES 4–8 ) 1.02–1.09 times as long as wide; punctation very dense, moderately coarse, distinctly umbilicate and partly confluent, interstices lacking microsculpture; postocular portion approximately twice as long as eye length.

Pronotum ( Fig. 4 View FIGURES 4–8 ) 1.16–1.21 times as long as wide, 0.99–1.05 times as long and 0.88–0.92 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with short and narrow impunctate elevation; interstices without microsculpture.

Elytra ( Fig. 4 View FIGURES 4–8 ) 0.52–0.59 times as long as wide, 0.43–0.49 times as long and 0.95–1.00 times as broad as pronotum; punctation as dense and coarse as that of pronotum; interstices lacking microsculpture.

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

Male. Sternite VII ( Fig. 5 View FIGURES 4–8 ) with posterior margin shallowly emarginated in the middle. Sternite VIII ( Fig. 6 View FIGURES 4–8 ) with triangular posterior excision.Aedeagus ( Figs 7, 8 View FIGURES 4–8 ) moderately sclerotized, ventral process wide in ventral view, roundly protruding at apex, with pair of subtriangular basal laminae ventrally; dorso-lateral apophyses moderately slender in ventral view, distinctly curved, with narrow apex in lateral view, extending beyond apex of ventral process.

Distribution and habitat data. The species is known only from the Dayao Mountains in middle Guangxi. The specimens were collected by sifting leaf litter at altitudes of 1,150 –1,400 m.

Comparative notes. The new species is very similar to N. dayaoensis (in Hu et al. 2012: 36, Figs 1–6 View FIGURES 1–3 View FIGURES 4–8 ) in general appearance from the same locality, but can be separated by the aedeagal characters: ventral process wider and shorter in ventral view; dorso-lateral apophyses wider, extending beyond apex of ventral process. The new species is also similar to N. damingshanus Hu & Li (in Hu et al. 2013: 87, Figs 1–6 View FIGURES 1–3 View FIGURES 4–8 ), but can be separated by the aedeagal characters: ventral process longer, roundly protruding at apex in ventral view; dorso-lateral apophyses with narrow apex in lateral view.

Etymology. The specific epithet is derived from the name of the type locality: Shengtang Shan.
