Type material.

Holotype: China: ♂: "China: Hunan Prov., Yongzhou County, Dupangling N. R., 25°26'12.45"N, 111°20'23.29"E, 448 m, 29.viii.2020, sifted, Chong Li leg." (SNUC).

Description.

Body length 4.7 mm; forebody length 2.4 mm.

Body (Fig. 4 ) reddish brown; antennae and legs yellowish brown.

Head (Fig. 22 ) 0.97 times as long as wide; punctation very dense, moderately coarse, distinctly umbilicate and partly confluent, interstices lacking microsculpture; postocular portion approximately 1.6 times as long as eye length.

Pronotum (Fig. 22 ) 1.17 times as long as wide, as long as and 0.83 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with short and very narrow impunctate elevation; interstices lacking microsculpture.

Elytra (Fig. 22 ) 0.77 times as long as wide, 0.66 times as long and as broad as pronotum; punctation as dense as, and slightly coarser than that of pronotum; interstices lacking microsculpture.

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

Male. Sternite VII (Fig. 23 ) with posterior margin shallowly emarginate in the middle. Sternite VIII (Fig. 24 ) with triangular posterior excision. Aedeagus (Figs 25 , 26 ) with broad ventral process, slightly widened in apical half, with round apex in ventral view, with pair of heart-like basal laminae; dorso-lateral apophyses slender, distinctly curved in ventral view, curved dorsally and slightly widened at apices in lateral view, extending beyond apex of ventral process.

Distribution and habitat data.

The species is known only from Dupangling in southern Hunan (Fig. 27 ). The specimen was collected by sifting leaf litter at an altitude of 448 m.

The new species is similar in general appearance and aedeagal characters to N. rubidus and N. nanlingensis , but can be separated by the slightly dorsally curved dorso-lateral apophyses of the aedeagus in lateral view (Fig. 26 ), and by the heart-like basal laminae of the ventral process (Fig. 25 ).

Etymology.

The species is named in honor of Chong Li, who collected some of the type specimens.
