( Figs 3 , 14–19 ) Type material. Holotype : China : male: ‘ China : Guangxi , Jinxiu County , Yinshan Conservation Station , 24°10′01″N , 110°14′38″E , mixed leaf litter, sifted, 1200 m , 10–11.VII.2014 , Peng , Song , Yu & Yan leg.’ ( SNUC ). Description. Body length 7.8 mm ; forebody length 4.1 mm . Body ( Fig. 3 ) dark brown; antennae and legs yellowish brown. Head ( Fig. 14 ) 1.07 times as long as wide; punctation very dense, moderately coarse, non-umbilicate, interstices lacking microsculpture; postocular portion approximately twice as long as eye length. Pronotum ( Fig. 14 ) 1.21 times as long as wide, 0.96 times as long and 0.84 times as broad as head; punctation non-umbilicate, moderately dense and as coarse as that of head; midline posteriorly with long and very narrow impunctate elevation; interstices without microsculpture. Elytra ( Fig. 14 ) 0.61 times as long as wide, 0.51 times as long and as broad as pronotum; punctation as dense and coarse as 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. 15 ) with posterior margin nearly truncate in the middle. Sternite VIII ( Fig. 16 ) with triangular posterior excision. Aedeagus ( Figs 17, 18 ) well sclerotized, ventral process wide at base, with small triangular excision at apex in ventral view, with pair of curved basal laminae ventrally; dorso-lateral apophyses widened in apical half in ventral view, curved to dorsal side and slightly widened at apex in lateral view, extending beyond apex of ventral process. Distribution and habitat data. The species is known only from the Dayao Mountains in middle Guangxi . The specimens were collected by sifting mixed leaf litter at an altitude of 1,200 m . Comparative notes. The new species is similar to N. inaequalis Assing (Assing 2014: 26, Figs 53–59; Hu et al. 2018: 183, Figs 4–11 ) in general appearance from Jiangxi , Hunan and Guangdong , but can be separated by the posterior margin of male sternite VIII lacking dense long setae; dorso-lateral apophyses of aedeagus much longer, extending beyond the apex of ventral process. Etymology. The specific epithet is composed of the Latin words ‘curvatus’ and ‘lamina’, indicating the curved basal laminae of the ventral process.
