Paratypes: 5 males, 6 females, same data as holotype; 2 males, 4 females, same data, except " 26°18′10″N, 114°00′12″E, 1620 m, 26.V.2014 "; 14 males, 6 females, " China: Hunan Province, Guidong Co., Bamian Shan, 25°59′33″N, 113°42′25″E, mixed forest, leaf litter, wood, sifted, 1510 m, 01.VI.2014, Peng, Shen, Yu & Yan"; 1 male, " China: Hunan Province, Guidong Co., Bamian Shan, 25°58′53″N, 113°42′43″E, mixed forest, shrub, flower, sifted & beating, ca. 1100 m, 04.VI.2014, Peng, Shen, Yu & Yan".
Description. Body length 4.2–4.6 mm; forebody length 2.4–2.5 mm.
Body (Fig. 3) reddish brown; antennae and legs yellowish brown.
Head (Fig. 17) approximately as long as wide; punctation very dense, rather coarse, not confluent, and nonumbilicate, interstices without microsculpture; postocular portion approximately twice as long as eye length.
Pronotum (Fig. 17) 1.09–1.12 times as long as wide, 1.01–1.03 times as long and 0.89–0.93 times as broad as head; punctation non-umbilicate, moderately dense and coarse; midline with or without very narrow impunctate elevation in posterior half; interstices without microsculpture.
Elytra (Fig. 17) 0.65–0.73 times as long as wide, 0.56–0.63 times as long and 0.94–0.97 times as broad as pronotum; punctation as coarse and as dense as that of pronotum; interstices with fine microsculpture.
Abdomen with punctation dense and coarse on tergites III–IV, less dense and finer on tergites V–VI, sparse and fine on tergites VII–VIII; interstices with fine microsculpture.
Male. Sternite VII (Fig. 18) with posterior margin shallowly concave in the middle. Sternite VIII (Fig. 19) with triangular posterior excision. Aedeagus (Figs 20, 21) well sclerotized; ventral process short, gradually narrowed apically in ventral view, with pair of wing-like basal laminae ventrally; dorso-lateral apophyses slightly curved, narrowed in apical half and with truncate apex in ventral view, curved ventrally and slightly widened at apex in lateral view, extending beyond apex of ventral process.
Comparative notes. This new species is highly similar to N. rufus Hu & Li, 2015 from Luoxiao Mountains in general appearance and separated only by aedeagal characters: apex of the ventral process in lateral view much broader (Fig. 21), dorso-lateral apophyses much narrower in ventral view (Figs 20), and curved ventrally in lateral view (Fig. 21).
Distribution and habitat data. This species was found in two adjacent localities in southeastern Hunan (Fig. 22). The specimens were collected by sifting leaf litter at altitudes of 1100–1730 m.
Etymology. The species is dedicated to Jia-Wei Shen, who collected some of the type specimens.
