( Figs 2View FIGURES 1–3, 12–16View FIGURES 12–16, 22View FIGURE22)

Type material. Holotype: CHINA: male: " China: W. Jiangxi, Ji'an City, Jinggang Shan , Jingzhu Shan , 26°29′45″N, 114°04′45″E, mixed leaf litter, sifted, 1160 m, 31.VII.2014, Chen, Hu, Lv & Yu leg." ( SNUC)GoogleMaps  . Paratypes: 4 males, 3 females, same data as holotypeGoogleMaps  ; 1 male, 1 female, same data as holotype except " 2.VIII.2011 ".GoogleMaps 

Description. Body length 5.6–6.2 mm; forebody length 3.2–3.5 mm.

Body ( Fig. 2View FIGURES 1–3) dark brown; antennae and legs yellowish brown.

Head ( Fig. 12View FIGURES 12–16) 1.02–1.05 times as long as wide; punctation dense and coarse, not confluent, and nonumbilicate, interstices without microsculpture; postocular portion approximately twice as long as eye length.

Pronotum ( Fig. 12View FIGURES 12–16) 1.13–1.16 times as long as wide, approximately as long and 0.89–0.91 times as broad as head; punctation as dense and as coarse as that of head; midline with narrow and short impunctate elevation in posteriorly third; interstices without microsculpture.

Elytra ( Fig. 12View FIGURES 12–16) 0.63–0.68 times as long as wide, 0.55–0.59 times as long and as broad as pronotum; punctation as dense and as coarse as that of pronotum; interstices without microsculpture.

Abdomen with punctation dense and coarse on tergites III–V, dense and less coarse on tergite VI, moderately dense and fine on tergites VII–VIII; apical third of tergites III–VIII with very fine microsculpture.

Male. Sternite VII ( Fig. 13View FIGURES 12–16) with posterior margin shallowly concave in the middle. Sternite VIII ( Fig. 14View FIGURES 12–16) with triangular posterior excision. Aedeagus ( Figs 15, 16View FIGURES 12–16) moderately sclerotized; ventral process long, constricted near middle, apex divided into two dorsally curved branches in ventral view; dorso-lateral apophyses widened in apical half, not reaching apex of ventral process.

Comparative notes. The new species is similar to N. inaequalis  in general appearance and separated by the following character combination: apical third of tergites III–VIII with very fine microsculpture; ventral process symmetrical and longer in ventral view ( Fig. 15View FIGURES 12–16), dorso-lateral apophyses longer ( Fig. 15View FIGURES 12–16).

Distribution and habitat data. This species is known only from Jinggang Shan in southwestern Guangxi ( Fig. 22View FIGURE22). The specimens were collected by sifting leaf litter at an altitude of 1160 m.

Etymology. This species is dedicated to Yi-Ping Chen, who collected some of the type specimens.
