Type material.

Holotype: China: ♂: "China: Guangdong Prov., Shixing County, Chebaling N. R., 24°43'22"N, 114°15'22"E, 357 m, 19.viii.2020, Liang Tang leg." (SNUC). Paratypes: 1 ♂, same data as holotype; 1 ♂, 2 ♀♀, "China: Jiangxi Prov., Longnan County, Jiulianshan N. R., 24°30'59.23"N, 114°24'52.98"E, alt. 587 m, 16.viii.2020, Liang Tang leg." (SNUC).

Description.

Body length 6.4-7.5 mm; forebody length 3.2-3.4 mm.

Body (Fig. 1 View Figures 1–4 ) dark brown; legs yellowish brown; antennae dark brown to light brown.

Head (Fig. 5 View Figures 5–9 ) 1.02-1.12 times as long as wide; punctation very dense, moderately coarse, non-umbilicate, interstices lacking microsculpture; postocular portion approximately 1.6-2.1 times as long as eye length.

Pronotum (Fig. 5 View Figures 5–9 ) 1.18-1.22 times as long as wide, 0.95-1.02 times as long and 0.83-0.91 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. 5 View Figures 5–9 ) 0.59-0.67 times as long as wide, 0.50-0.57 times as long and 0.96-1.09 times 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. 6 View Figures 5–9 ) with posterior margin truncate at middle. Sternite VIII (Fig. 7 View Figures 5–9 ) with wide triangular posterior excision. Aedeagus (Figs 8 View Figures 5–9 , 9 View Figures 5–9 ) well sclerotized; with ventral process narrowed near middle in ventral view, with U-shaped excision at apex in ventral view, with pair of wing-like basal laminae ventrally; dorso-lateral apophyses moderately strong, 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 from Chebaling in northern Guangdong and Jiulianshan in southern Jiangxi (Fig. 27 View Figure 27 ). The specimens were collected by sifting leaf litter at altitudes of 357-587 m.

Comparative notes.

The new species is very similar to N. inaequalis Assing, 2014 in general appearance and separated only by the aedeagal characters: the apex of the ventral process is symmetric in ventral view (Fig. 8 View Figures 5–9 ); dorso-lateral apophyses extending beyond the apex of the ventral process.

Etymology.

The species is named in honor of Xing-Min Wang (South China Agricultural University) who helped a lot during our collection in Nanling.
