Description. Body length 3.9–5.2 mm; forebody length 2.3–2.6 mm.

Body ( Fig. 6 View FIGURES 6–8 ) reddish brown to dark reddish brown; antennae and legs yellowish brown.

Head ( Fig. 9 View FIGURES 9–13 ) approximately 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. 9 View FIGURES 9–13 ) 1.15–1.22 times as long as wide, approximately as long and 0.82–0.92 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. 9 View FIGURES 9–13 ) 0.63–0.66 times as long as wide, 0.51–0.56 times as long and 0.94–1.03 times as broad as pronotum; punctation similar to 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. 10 View FIGURES 9–13 ) with posterior margin shallowly concave in the middle. Sternite VIII ( Fig. 11 View FIGURES 9–13 ) with triangular posterior excision. Aedeagus ( Figs 12, 13 View FIGURES 9–13 ) with ventral process broad in apical half and apex widely rounded in ventral view, with pair of wing-like basal laminae ventrally; dorso-lateral apophyses moderately slender, distinctly curved near apex in ventral view, nearly straight in lateral view, extending beyond apex of ventral process.

Distribution and habitat. The species is known from Nanling in northern Guangdong and Mangshan in southern Hunan. The specimens were collected by sifting leaf litter at altitudes of 700–1820 m.

Comparative notes. The new species is very similar to N. huapingensis Hu & Li in general appearance and aedeagal characters, but can be separated by the following combination of characters: posterior excision of male sternite VIII wider ( Fig. 11 View FIGURES 9–13 ); apex of ventral process of aedeagus widely rounded in ventral view ( Fig. 12 View FIGURES 9–13 ); dorsolateral apophyses nearly straight in lateral view ( Fig. 13 View FIGURES 9–13 ).

Etymology. The specific epithet (Latin, adjective: reddish) alludes to the body coloration.
