Nazeris damingshanus Hu & Li , sp. n.

( Figs. 1–6 )

Type material. Holotype: CHINA: male: labeled ‘ China : Guangxi Prov., Wuming County, Damingshan N. R., 1200 m, 28-VII-2012, Hu & Song leg. ’. Paratypes: 2 males, 2 females, same label data as holotype ; 3 males, 1 female, same data, except ‘ 1300 m, 29-VII-2012 ’; 2 males, 3 females, same data, except ‘ 1500 m, 29-VII-2012 ’; 11 males, 12 females, same data, except ‘ 1200–1300 m, 30-VII-2012 ’.

Diagnosis. Body reddish brown, small in size; head with umbilicate punctation; abdominal tergites lacking microsculpture; aedeagal median lobe with round apex, and with a pair of round processes near apical 1/4.

Description. Body length 4.1–4.7 mm; forebody length 2.3–2.5 mm.

Male. Body ( Fig. 1 ) reddish brown, with abdominal segments 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 1.72 times as long as eye length; with umbilicate punctation coarse and dense.

Pronotum longer than wide (length/width = 1.15), narrower than (pronotum/head = 0.88) and as long as head; prosternum with strong longitudinal median carina extending to anterior margin. Elytra shorter than wide (length/ width = 0.89), shorter than (elytra/pronotum = 0.77) and as wide as pronotum.

Abdomen elongate, tergites lacking microsculpture. Sternite VII ( Fig. 2 ) with posterior margin slightly emarginated at middle, area anterior to emargination not depressed. Sternite VIII ( Fig. 3 ) with posterior margin triangularly concaved at middle. Aedeagus ( Figs. 4–6 ) well sclerotized; median lobe short and wide, with round laminae near apical 1/4 on ventral side; dorso-lateral apophysis strong, slightly curved mesally in dorsal or ventral view, 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 Hu & Li and N. tani Hu & Li in general appearance, but can be separated by the slightly darker coloration, and the different aedeagal structure.

Etymology. The specific name is derived from the name of the type locality, Daming Shan.
