( Figs 7 , 15–19 , 30 ) Type material. Holotype : CHINA : male: " China : Guangxi Prov., Lingui County , Huaping N. R. , Anjiangping , 1780 m , 17.VII.2011 , Zhu Jian-Qing leg. " ( SNUC ) . Paratypes : 3 females , same data as holotype except " 1700 m , 17.VII.2011 , Peng Zhong leg." . Description. Body length 5.6–6.1 mm ; forebody length 3.1–3.3 mm . Body ( Fig. 7 ) dark brown; antennae and legs yellowish brown. Head ( Fig. 15 ) approximately as long as wide; punctation dense and coarse, non-umbilicate, interstices without microsculpture; postocular portion approximately twice as long as eye length. Pronotum ( Fig. 15 ) 1.14–1.19 times as long as wide, 0.93–0.96 times as long and 0.80–0.83 times as broad as head; punctation as dense and as coarse as that of head; midline with narrow impunctate elevation in posteriorly half; interstices without microsculpture. Elytra ( Fig. 15 ) 0.64–0.67 times as long as wide, 0.54–0.57 times as long and as broad as pronotum; punctation as dense and slightly coarser than that of pronotum; interstices without 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. 16 ) with posterior margin truncate at middle. Sternite VIII ( Fig. 17 ) with wide posterior excision. Aedeagus ( Figs 18, 19 ) well sclerotized; ventral process very short, with parallel sides, with distinctly incised apex in ventral view, and with pair of wing-shaped basal laminae ventrally; dorso-lateral apophyses slender, with acute apex, extending much beyond apex of ventral process. Distribution and habitat data. The species is known only from Huaping in northeast Guangxi ( Fig. 30 ). The specimens were collected by sifting leaf litter at altitudes of 1700–1780 m . FIGURES 15–19. Nazeris alatus 15–forebody; 16–male sternite VII; 17–male sternite VIII; 18–aedeagus, in ventral view; 19– aedeagus, in lateral view. Scale bars: 15: 1 mm, 16–19: 0.5 mm Comparative notes. The new species is distinguished from all the known species of Nazeris from Guangxi and adjacent regions by the following combination of characters: punctation of head non-umbilicate ( Fig. 15 ); ventral process of the aedeagus very short ( Fig. 18 ); dorso-lateral apophyses long and apically acute ( Fig. 18 ). Etymology. The specific epithet (Latin, adjective: with wings) alludes to the wing-shaped basal laminae of ventral process of the aedeagus.
