Nazeris tani Hu & Li , sp. n.

( Figs. 13–18 )

Type material. Holotype: male, labeled China: Guangxi Province / Jinxiu County / Dayaoshan N. R. / Lianhuashan / alt. 1100 m, 30-VII-2011 / HU Jia-Yao leg. Paratypes: 5 males, 3 females, same label data as holotype; 2 male, 1 female, same data, except PENG Zhong leg.

Description. Body length 4.0– 4.7 mm; forebody length 2.4–2.6 mm.

Male. Body ( Fig. 13 ) reddish brown, with abdominal segments VI and VII somewhat darker, antennal segments (except for basal two ones), maxillary palpi and legs (except for coxae) yellow.

Head about as long as wide; postocular portion 1.77 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 36.0 (9.0): 12.0 (6.0): 20.0 (4.5): 17.0 (4.5): 17.0 (4.5): 17.0 (4.5): 15.0 (4.0): 14.0 (4.0): 13.5 (4.0): 12.0 (5.0): 16.0 (5.5).

Pronotum longer than wide (length/width = 1.18), narrower than (pronotum/head = 0.87) and as long as head; prosternum with strong longitudinal median carina extending to anterior margin. Elytra shorter than wide (length/ width = 0.92), shorter than (elytra/pronotum = 0.78) and as wide as pronotum.

Abdomen elongate, tergites lacking microsculpture. Sternite VII ( Fig. 14 ) with posterior margin slightly emarginated at middle, area anterior to emargination not depressed. Sternite VIII ( Fig. 15 ) with posterior margin triangularly concaved at middle. Aedeagus ( Figs. 16–18 ) well sclerotized; median lobe with lateral margins angularly expanded laterally twice below apex in dorsal or ventral view, with crescent laminae near apical fourth on dorsal side, lacking apical tubercles on ventral side, and with apex nearly truncate; dorso-lateral apophysis strong, slightly narrowed below apices, slightly curved mesally in dorsal or ventral view and distinctly curved dorsally in lateral view, extending much beyond apex of median lobe.

Female. Sternites VII and VIII simple. Other characters similar to those of male.

Distribution. South China: Guangxi.

Remarks. The new species highly resembles N. luoi in general appearance, and can be separated only by the different aedeagal structure: the median lobe lacks apical tubercles, with a pair of crescent laminae near apical fourth, while in N. luoi the median lobe has a pair of apical tubercles and round laminae on the ventral side.

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