Nazeris qini Hu & Li , sp. n.

( Figs. 19–24 )

Type material. Holotype: male, labeled China: Guangxi Province / Jinxiu County / Dayaoshan N. R. / Shengtangshan / alt. 1900 m, 26-VII-2011 / PENG Zhong leg.

Description. Body length 4.2 mm; forebody length 2.3 mm.

Male. Body ( Fig. 19 ) reddish brown, with apical half of each abdominal segment darker, antennal segments (except for basal two ones) and maxillary palpi yellow, legs (except for coxae) yellowish brown.

Head longer than wide (length/width = 1.07); postocular portion 2.14 times as long as eye length; with umbilicate punctation coarse and dense. Antennae slender; relative length (width) of each antennomere from I to XI as 26.0 (8.0): 10.0 (5.5): 15.0 (4.0): 12.0 (4.0): 12.0 (4.0): 12.0 (4.5): 11.0 (4.5): 10.5 (4.0): 10.0 (4.5): 10.0 (5.0): 13.0 (5.5).

Pronotum longer than wide (length/width = 1.20), narrower than (pronotum/head = 0.89) and as long as head; prosternum with strong longitudinal median carina extending to anterior margin. Elytra as long as wide, shorter (elytra/pronotum = 0.78) and narrower (elytra/pronotum = 0.92) than pronotum.

Abdomen elongate, with fine microsculpture on all tergites. Sternite VII ( Fig. 20 ) with posterior margin slightly emarginated at middle, area anterior emargination not depressed. Sternite VIII ( Fig. 21 ) with posterior margin triangularly concaved at middle. Aedeagus ( Figs. 22–24 ) well sclerotized; median lobe with lateral margins slightly arcuate, gradually narrowed toward apex in dorsal or ventral view, with pair of nearly round laminae at middle on dorsal side; dorso-lateral apophysis slender, slightly curved mesally in dorsal or ventral view and nearly straight in lateral view, extending slightly beyond apex of median lobe.

Female. Unknown.

Distribution. South China: Guangxi.

Remarks. The new species is similar to N. zhangi Watanabe & Xiao from Yunnan in appearance, but can be distinguished by the following characters: abdomen with fine microsculpture on all tergites (without microsculpture in N. zhangi ); the median lobe with a pair of nearly round laminae on dorsal side (lacking processes in N. zhangi ) ( Watanabe & Xiao 1993: 132, fig. 3).

Etymology. The species is named in honor of Kun Qin (Administration of Dayaoshan National Nature Reserve) who helped a lot during our collecting in Guangxi.
