Type material. Holotype: CHINA: male, ‘ China: Xizang, Dinggyê County, pass to Zhêntang Town , 27°53′58″N, 87°27′21″E, 3060 m, 28.vi.2021, Peng, Yin & Zhang leg. (ƱAEṪDZƂḴaefflẅøṁ⁂ḩ)’ ( SNUC) GoogleMaps . Paratypes: 2 males, 1 female, same data as holotype GoogleMaps ; 1 female, same data GoogleMaps , except ‘ Zhêntang Town , Xiuxiongma Vill., 27°54′11″N, 87°22′42″E, 2700–3000 m, 25.vi.2021.

Diagnosis. Body reddish brown to dark brown; head with non-umbilicate punctation, shaped like sunflower seed; abdominal tergites lacking microsculpture; aedeagal ventral process distinctly narrowed near apical third in ventral view; dorso-lateral apophyses with wide apex in ventral view, not reaching apex of ventral process.
Description. Body length 6.2–6.4 mm; forebody length 3.3–3.4 mm.
Body ( Fig. 1B View FIGURE 1 ) reddish brown to dark brown; antennae and legs yellowish brown.
Head ( Fig. 2B View FIGURE 2 ) 1.05–1.11 times as long as wide; punctation very dense, moderately coarse and non-umbilicate, shaped like sunflower seed; interstices lacking microsculpture; postocular portion 2.2–2.3 times as long as eye length.
Pronotum ( Fig. 2B View FIGURE 2 ) 1.15–1.24 times as long as wide, 0.90–0.95 times as long and 0.80–0.87 times as broad as head; punctation non-umbilicate, moderately dense, slightly coarser than that of head; midline posteriorly with very short and narrow impunctate elevation; interstices lacking microsculpture.
Elytra ( Fig. 2B View FIGURE 2 ) 0.65–0.72 times as long as wide, 0.56–0.65 times as long and 1.01–1.07 times as broad as pronotum; punctation similar to that of pronotum; interstices lacking microsculpture.
Abdomen ( Fig. 1B View FIGURE 1 ) with punctation dense and rather coarse on tergites III–IV, dense and less coarse on tergites V–VI, moderately dense and fine on tergites VII–VIII; interstices lacking microsculpture ( Fig. 4A View FIGURE 4 ).
Male. Sternite VII ( Fig. 4B View FIGURE 4 ) with posterior margin shallowly concaved in the middle. Sternite VIII ( Fig. 4C View FIGURE 4 ) with V-shaped posterior excision. Aedeagus ( Figs 4D–G View FIGURE 4 ) weakly sclerotized; ventral process distinctly narrowed near apical third in ventral view; dorso-lateral apophyses slender, with wide apex in ventral view, not reaching apex of ventral process.
Distribution and habitat data. The species in known only from Dinggyê County in southern Xizang ( Fig. 10H View FIGURE 10 ). The specimen was collected by sifting leaf litter at attitudes of 2700–3060 m.
Comparative notes. The new species is very similar to N. mirabilis in general appearance, especially the punctation of head, but can be separated by abdominal tergites lacking microsculpture ( Fig. 4A View FIGURE 4 ) and distinctly slender ventral process of aedeagus in ventral view ( Figs 4D, E View FIGURE 4 ).
Etymology. The specific epithet is derived from the name of the type locality: Dinggyê.
