( Figs. 2 , 9–13 , 20 ) Type material. Holotype : CHINA : male: " China : Xizang A. R., Cuona County , Lebu , 2450–2700 m , 19.VIII.2010 , Jian-Qing Zhu leg." ( SNUC ) . Paratypes : 2 females , same data as holotype ( SNUC ) . Description. Body length 4.4–4.7 mm ; forebody length 2.7–2.9 mm . Body ( Fig. 2 ) brown to reddish brown; antennae and legs brown. Head ( Fig. 9 ) 1.05 times as long as wide; punctation moderately dense and coarse, non-umbilicate and not confluent, interstices without microsculpture; postocular portion 2.07 times as long as eye length. Pronotum ( Fig. 9 ) 1.20 times as long as wide, 0.82 times as broad and 0.94 times as long 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. 9 ) 0.72 times as long as wide, 0.63 times as long and 1.05 times as broad as pronotum; punctation as dense and as coarse as that of pronotum; interstices without microsculpture. FIGURES 9–13 . Nazeris zhujianqingi 9—forebody; 10—male sternite VII; 11—male sternite VIII; 12—aedeagus, in ventral view; 13—aedeagus, in lateral view. Scale bars: 9: 1 mm, 10–13: 0.5 mm Abdomen with punctation dense and 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 ) with shallow and broad posterior excision at middle. Sternite VIII ( Fig. 11 ) with shallow median impression, this impression with a cluster of dense long setae, posterior excision V-shaped. Aedeagus ( Figs. 12, 13 ) with ventral process narrowed apically, laterally compressed, sharply edged ventrally; dorso-lateral apophyses short and slender, strongly curved subapically in ventral view, not reaching apex of ventral process. Distribution and habitat data. The species is known only from Cuona in southern Xizang ( Fig. 20 ). The specimens were collected at altitude of 2450–2700 m . Comparative notes. Based on the moderately coarse punctation of the head, the transverse male sternite VII with a broadly concave posterior margin, and the impressed male sternite VIII with modified pubescence, N. zhujianqingi belongs to the N. flavocaudatus group. The new species is similar to N. flavapicalis Assing, 2014 in general appearance and aedeagal characters, but can be separated by the less dense and coarse punctation of the head ( Fig. 9 ), by the shorter and wider ventral process of the aedeagus in lateral view ( Fig. 13 ), and by the more strongly curved dorso-lateral apophyses of the aedeagus in ventral view ( Fig. 12 ). Etymology. The species is named in honor of Jian-Qing Zhu, collector of the new species.
