Description.
Body length: 5.8-6.4 mm; forebody length: 3.3-3.5 mm.
Male. Body (Fig. 1) elongate, dark brown, with labrum, coxae, and basal antennomeres reddish yellow, the remaining antennomeres, maxillary palpi and legs yellow, with exception for coxae.
Head suborbicular, longer than wide (length/width = 1.18); postocular portion 1.96 times as long as eye length; punctation coarse, dense, and umbilicate; interstices reduced to narrow ridges. Antennae slender; relative length of each segment from 1 to 11: 42.0: 15.0: 29.0: 23.0: 22.5: 22.0: 19.0: 17.0: 15.5: 14.0: 20.0; relative width of each segment from 1 to 11: 12.0: 7.5: 6.0: 6.0: 6.0: 6.0: 6.0: 6.0: 6.0:7.5: 7.5.
Pronotum convex, oval, longer than wide (length/width = 1.20), narrower (pronotum/head = 0.93) and shorter (pronotum/head = 0.94) than head; prosternum with strong longitudinal median carina, which disappears behind anterior margin. Elytra shorter than wide (length/width = 0.91), distinctly shorter (elytra/pronotum = 0.74) and slightly narrower (elytra/pronotum = 0.97) than pronotum.
Abdomen elongate, tergites without any microsculpture. Seventh sternite (Fig. 3) trapezoidally emarginated in middle of posterior margin and distinctly depressed in front of emargination; 8th sternite (Fig. 4) V-shaped deeply excised in middle of posterior margin. Aedeagus (Figs. 5, 6 and 7) well sclerotized; apical part of me dian lobe in dorsal view tri-lobed, median part cone-shaped, two outer parts acute at apices, with little agnail in each outer side near apex; dorso-lateral apophyses slightly curved inward, distinctly widened near apex, extending beyond apices of median lobe.
Female. Seventh and 8th sternites simple. The other characters are similar to those of male.
Remarks.
The new species is similar to Nazeris daliensis Watanabe (1997: 7) from Yunnan Province in appearance, but it can be distinguished from the latter by the following characters: elytra slightly narrower than pronotum (in Nazeris daliensis nearly as wide as, or slightly broader than pronotum); depth of excision of male 8th sternite nearly half of middle length of sternite (in Nazeris daliensis much shallower, nearly 1/3 of middle length of 8th sternite); apical part of median lobe of aedeagus in dorsal view tri-lobed (in Nazeris daliensis not lobed). The new species can be distinguished from Nazeris coomani Jarrige (1948: 40) from Vietnam by head with umbilicate punctation (in Nazeris coomani punctation of head simple) and distinguished from Nazeris odzisan Watanabe (1996: 1) from Vietnam by elytra shorter than wide (in Nazeris odzisan elytra longer than wide); dorso-lateral apophyses of aedeagus extending beyond apices of median lobe (in Nazeris odzisan not extending to apices of median lobe).
Etymology.
The specific name is derived from the name of the type locality: Nabanhe Nature Reserve.
