( Figs 9 , 25–30 ) Type material. Holotype : CHINA : male: " China : Guangxi Prov., Lingui County , Huaping N. R. , Anjiangping , 1200 m , 13.VII.2011 , Zhu , Chen & Ma leg." ( SNUC ). Description. Body length 6.7 mm ; forebody length 3.2 mm . Body ( Fig. 9 ) dark brown; antennae and legs yellowish brown. Head ( Fig. 25 ) 1.03 times as long as wide; punctation very dense, moderately coarse, distinctly umbilicate, interstices without microsculpture; postocular portion approximately twice as long as eye length. Pronotum ( Fig. 25 ) 1.18 times as long as wide, approximately as long and 0.89 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with very short and narrow impunctate elevation; interstices without microsculpture. Elytra ( Fig. 25 ) 0.69 times as long as wide, 0.59 times as long and as broad as pronotum; punctation as dense as, and less coarse than that of pronotum; interstices without microsculpture. Abdomen with punctation dense and rather coarse on tergites III, dense and less coarse on tergite VI–V, moderately dense and fine on tergites VII–VIII; interstices lacking microsculpture. Male . Sternite VII ( Fig. 26 ) with posterior margin truncate at middle. Sternite VIII ( Fig. 27 ) with V-shaped posterior excision. Aedeagus ( Figs 28, 29 ) moderately sclerotized; ventral process long, dorsal parts widened near middle and at apex in ventral view, with pair of triangular basal laminae ventrally; dorso-lateral apophyses slender, extending slightly beyond apex of ventral process. Distribution and habitat data. The species is known only from Huaping in northeast Guangxi ( Fig. 30 ). The specimen was collected by sifting leaf litter at an altitude of 1200 m . Comparative notes. The new species is similar in general appearance and aedeagal characters to N. shaanxiensis Hu, Li & Zhao , but can be separated by denser and coarser punctation of the pronotum a wider ventral process of the aedeagus ( Fig. 28 ), and by narrower and longer dorso-lateral apophyses ( Figs 28 ). Etymology. The species is named in honor of Yan Chen, who collected some of the type specimens.
