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) . Paratypes: 4 males, 3 females, same data as holotype; 1 male, 1 female, same data as holotype except " 2.VIII.2011 ".

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

Body (Fig. 2) dark brown; antennae and legs yellowish brown.

Head (Fig. 12) 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. 12) 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. 12) 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. 13) with posterior margin shallowly concave in the middle. Sternite VIII (Fig. 14) with triangular posterior excision. Aedeagus (Figs 15, 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. 15), dorso-lateral apophyses longer (Fig. 15).

Distribution and habitat data. This species is known only from Jinggang Shan in southwestern Guangxi (Fig. 22). 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.
